Risks related to our business and industry

We have a history of operating losses, and we may not be able to generate sufficient revenue to achieve and sustain profitability.

We have not yet achieved profitability. We incurred net losses of $42.6 million and $4.0 million for the year ended December 31, 2019 and the three months ended March 31, 2020, respectively, as compared to $38.9 million and $10.5 million for the year ended December 31, 2018 and the three months ended March 31, 2019, respectively. As of March 31, 2020, we had an accumulated deficit of $280.7 million. While we have experienced significant revenue growth over recent periods, we may not be able to sustain or increase our growth or achieve profitability in the future. We intend to continue to invest in sales and marketing efforts, research and development, and expansion into new geographies. In addition, we expect to incur significant additional legal, accounting, and other expenses related to our being a public company as compared to when we were a private company. While our revenue has grown in recent years, if our revenue declines or fails to grow at a rate faster than these increases in our operating expenses, we will not be able to achieve and maintain profitability in future periods. As a result, we may continue to generate losses. We cannot assure you that we will achieve profitability in the future or that, if we do become profitable, we will be able to sustain profitability. Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays, and other unknown factors that may result in losses in future periods. If these losses exceed our expectations or our revenue growth expectations are not met in future periods, our financial performance will be harmed.

We have experienced strong growth in recent periods, and our recent growth rates may not be indicative of our future growth.

We have experienced strong growth in recent years. Our revenue was $112.1 million and $33.2 million for the year ended December 31, 2019 and the three months ended March 31, 2020, respectively, as compared to $91.9 million and $25.6 million for the year ended December 31, 2018 and the three months ended March 31, 2019, respectively. In future periods, we may not be able to sustain revenue growth consistent with recent history, or at all. We believe our revenue growth depends on a number of factors, including:

22

We may not accomplish any of these objectives and, as a result, it is difficult for us to forecast our future revenue or revenue growth. If our assumptions are incorrect or change in reaction to changes in our market, or if we are unable to maintain consistent revenue or revenue growth, our stock price could be volatile, and it may be difficult to achieve and maintain profitability. You should not rely on our revenue for any prior periods as any indication of our future revenue or revenue growth.

In addition, the catalyst for our revenue growth rate acceleration during the first quarter of 2020 was partner and service revenue, which increased 51.8% versus the same quarter in 2019. We may not be able to sustain such growth rates in the future.

Our future revenue and operating results will be harmed if we are unable to acquire new customers, retain existing customers, expand sales to our existing customers, or develop new functionality for our platform that achieves market acceptance.

To continue to grow our business, it is important that we continue to acquire new customers to purchase and use our platform. Our success in adding new customers depends on numerous factors, including our ability to: (1) offer a compelling ecommerce platform, (2) execute our sales and marketing strategy, (3) attract, effectively train and retain new sales, marketing, professional services, and support personnel in the markets we pursue, (4) develop or expand relationships with partners, payment providers, systems integrators, and resellers, (5) expand into new geographies and market segments, (6) efficiently onboard new customers on to our platform, and (7) provide additional paid services that complement the capabilities of our customers and their partners.

Our ability to increase revenue also depends in part on our ability to retain existing customers and to sell more functionality and adjacent services to our existing and new customers. Our customers have no obligation to renew their subscriptions for our solutions after the expiration of their initial subscription period. In order for us to maintain or improve our results of operations, it is important that our customers renew their subscriptions with us on the same or more favorable terms to us. Our ability to increase sales to existing customers depends on several factors, including their experience with implementing and using our platform, their ability to integrate our platform with other technologies, and our pricing model.

Our ability to generate revenue may be inconsistent across SMB, mid-market, and large enterprise customers. If we experience limited or inconsistent growth in any of these customer sets, particularly our mid-market and large enterprise customers, our business, financial condition, and operating results could be adversely affected.

If we are unable to provide enhancements, new features, or keep pace with current technological developments, our business could be adversely affected. If our new functionality and services initiatives do not continue to achieve acceptance in the market, our competitive position may be impaired, and our potential to generate new revenue or to retain existing revenue could be diminished. The adverse effect on our financial results may be particularly acute because of the significant research, development, marketing, sales, and other expenses we will have incurred in connection with the new functionality and services.

We face intense competition, especially from well-established companies offering solutions and related applications. We may lack sufficient financial or other resources to maintain or improve our competitive position, which may harm our ability to add new customers, retain existing customers, and grow our business.

The market for ecommerce solutions is evolving and highly competitive. We expect competition to increase in the future from established competitors and new market entrants. With the introduction of new technologies

23

and the entry of new companies into the market, we expect competition to persist and intensify in the future. This could harm our ability to increase sales, maintain or increase renewals, and maintain our prices. We face intense competition from other software companies that may offer related ecommerce platform software solutions and services. Our competitors include larger companies that have acquired ecommerce platform solution providers in recent years. We also compete with custom software internally developed within ecommerce businesses. In addition, we face competition from niche companies that offer point products that attempt to address certain of the problems that our platform solves.

Merger and acquisition activity in the technology industry could increase the likelihood that we compete with other large technology companies. Many of our existing competitors have, and our potential competitors could have, substantial competitive advantages such as greater name recognition, longer operating histories, larger sales and marketing budgets and resources, greater customer support resources, lower labor and development costs, larger and more mature intellectual property portfolios, and substantially greater financial, technical and other resources.

Some of our larger competitors also have substantially broader product lines and market focus and will therefore not be as susceptible to downturns in a particular market. Conditions in our market could change rapidly and significantly as a result of technological advancements, partnering by our competitors, or continuing market consolidation. New start-up companies that innovate, and large companies that are making significant investments in research and development, may invent similar or superior products and technologies that compete with our platform. In addition, some of our competitors may enter into new alliances with each other or may establish or strengthen cooperative relationships with agency partners, technology and application providers in complementary categories, or other parties. Furthermore, ecommerce on large marketplaces, such as Amazon, could increase as a percentage of all ecommerce activity, thereby reducing customer traffic to individual merchant websites. Any such consolidation, acquisition, alliance or cooperative relationship could lead to pricing pressure, a loss of market share, or a smaller addressable share of the market. It could also result in a competitor with greater financial, technical, marketing, service, and other resources, all of which could harm our ability to compete.

Some of our larger competitors use broader product offerings to compete, including by selling at zero or negative margins, by bundling their product, or by closing access to their technology platforms. Potential customers may prefer to purchase from their existing suppliers rather than a new supplier regardless of product performance or features. Furthermore, potential customers may be more willing to incrementally add solutions to their existing infrastructure from competitors than to replace their existing infrastructure with our platform. These competitive pressures in our market, or our failure to compete effectively, may result in price reductions, fewer orders, reduced revenue and gross margins, increased net losses, and loss of market share. Any failure to meet and address these factors could harm our business, results of operations, and financial condition.

The COVID-19 pandemic could materially adversely affect our business, financial condition and results of operations.

The COVID-19 pandemic, the measures attempting to contain and mitigate the effects of the COVID-19 pandemic, including stay-at-home, business closure, and other restrictive orders, and the resulting changes in consumer behaviors, have disrupted our normal operations and impacted our employees, suppliers, partners, and customers. We expect these disruptions and impacts to continue. In response to the COVID-19 pandemic, we have taken a number of actions that have impacted and continue to impact our business, including transitioning employees across all our offices (including our corporate headquarters) to remote work-from-home arrangements and imposing travel and related restrictions. While we believe these actions were reasonable and necessary as a result of the COVID-19 pandemic, they were disruptive to our business and could adversely impact our results of operations. Given the continued spread of COVID-19 and the resultant personal, economic, and governmental reactions, we may have to take additional actions in the future that could harm our business, financial condition, and results of operations. While we have a distributed workforce and our employees are accustomed to working

24

remotely or working with other remote employees, our workforce has not historically been fully remote. Prior to the COVID-19 pandemic, certain of our employees traveled frequently to establish and maintain relationships with one another and with our customers, partners, and investors. We continue to monitor the situation and may adjust our current policies as more information and guidance become available. Suspending travel and doing business in-person on a long-term basis could negatively impact our marketing efforts, our ability to enter into customer contracts in a timely manner, our international expansion efforts and our ability to recruit employees across the organization. These changes could negatively impact our sales and marketing in particular, which could have longer-term effects on our sales pipeline, or create operational or other challenges as our workforce remains predominantly remote, any of which could harm our business. In addition, our management team has spent, and will likely continue to spend, significant time, attention, and resources monitoring the COVID-19 pandemic and associated global economic uncertainty and seeking to manage its effects on our business and workforce.

The degree to which COVID-19 will affect our business and results of operations will depend on future developments that are highly uncertain and cannot currently be predicted. These development include but are not limited to the duration, extent, and severity of the COVID-19 pandemic, actions taken to contain the COVID-19 pandemic, the impact of the COVID-19 pandemic and related restrictions on economic activity and domestic and international trade, and the extent of the impact of these and other factors on our employees, suppliers, partners, and customers. The COVID-19 pandemic and related restrictions could limit our customers’ ability to continue to operate (limiting their abilities to obtain inventory, generate sales, or make timely payments to us). It could disrupt or delay the ability of employees to work because they become sick or are required to care for those who become sick, or for dependents for whom external care is not available. It could cause delays or disruptions in services provided by key suppliers and vendors, increase vulnerability of us and our partners and service providers to security breaches, denial of service attacks or other hacking or phishing attacks, or cause other unpredictable effects.

The COVID-19 pandemic also has caused heightened uncertainty in the global economy. If economic conditions further deteriorate, consumers may not have the financial means to make purchases from our customers and may delay or reduce discretionary purchases, negatively impacting our customers and our results of operations. Uncertainty from the pandemic may cause prospective or existing customers to defer investment in ecommerce. Our SMB customers may be more susceptible to general economic conditions than larger businesses, which may have greater liquidity and access to capital. Uncertain and adverse economic conditions also may lead to increased refunds and chargebacks. Since the impact of COVID-19 is ongoing, the effect of the COVID-19 pandemic and the related impact on the global economy may not be fully reflected in our results of operations until future periods. Volatility in the capital markets has been heightened during recent months and such volatility may continue, which may cause declines in the price of our Series 1 common stock.

Further, to the extent there is a sustained general economic downturn and our software is perceived by customers and potential customers as costly, or too difficult to deploy or migrate to, our revenue may be disproportionately affected by delays or reductions in general information technology spending. Competitors, many of whom are larger and more established than we are, may respond to market conditions by lowering prices and attempting to lure away our customers. In addition, the increased pace of consolidation in certain industries may result in reduced overall spending on our subscription offerings and related services. We cannot predict the timing, strength, or duration of any economic slowdown, instability, or recovery, generally or within any particular industry. If the economic conditions of the general economy or markets in which we operate worsen from present levels, our business, results of operations, and financial condition could be materially and adversely affected.

If we fail to adapt and respond effectively to rapidly changing technology, evolving industry standards, and changing customer needs or preferences, our platform may become less competitive.

The software industry is subject to rapid technological change, evolving industry standards and practices, and changing customer needs and preferences. The success of our business will depend, in part, on our ability to

25

adapt and respond effectively to these changes on a timely basis. If we are unable to develop and sell new technology, features, and functionality for our platform that satisfy our customers and that keep pace with rapid technological and industry change, our revenue and operating results could be adversely affected. If new technologies emerge that deliver competitive solutions at lower prices, more efficiently, more conveniently, or more securely, it could adversely impact our ability to compete.

Our platform must also integrate with a variety of network, hardware, mobile, and software platforms and technologies. We need to continuously modify and enhance our platform to adapt to changes and innovation in these technologies. If businesses widely adopt new ecommerce technologies, we would have to develop new functionality for our platform to work with those new technologies. This development effort may require significant engineering, marketing and sales resources, all of which would affect our business and operating results. Any failure of our platform to operate effectively with future technologies could reduce the demand for our platform. If we are unable to respond to these changes in a cost-effective manner, our platform may become less marketable and less competitive or obsolete, and our operating results may be negatively affected.

Our success depends in part on our partner-centric strategy. Our business would be harmed if we fail to maintain or expand partner relationships.

Strategic technology partners are essential to our open strategy. A significant percentage of our customers choose to integrate our ecommerce platform with third-party application providers using our open APIs and software development kits. The functionality and popularity of our platform depends, in part, on our ability to integrate our platform with third-party applications and platforms, including marketplaces and social media sites. We are dependent on strategic technology partner solutions for major ecommerce categories, including payments, shipping, tax, accounting, ERP, marketing, fulfillment, cross-channel commerce, and POS. We will continue to depend on various third-party relationships to sustain and grow our business. Third-party application providers’ sites may change the features of their applications and platforms or alter their governing terms. They may restrict our ability to add, customize or integrate systems, functionality and shopper experiences. Such changes could limit or terminate our ability to use these third-party applications and platforms and provide our customers a highly extensible and customizable experience. This could negatively impact our offerings and harm our business. Marketplaces or social networks that have allow limited integration into their platforms, such as Amazon, eBay, Facebook and Instagram, may discontinue our access or allow other platforms to integrate or integrate more easily. This would increase competition for ecommerce platforms across their solutions. Our business will be negatively impacted if we fail to retain these relationships for any reason, including due to third parties’ failure to support or secure their technology or our integrations; errors, bugs, or defects in their technology; or changes in our platform. Any such failure could harm our relationship with our customers, our reputation and brand, our revenue, our business, and our results of operations.

Strategic technology partners and third parties may not be successful in building integrations, co-marketing our platform to provide a significant volume and quality of lead referrals, or continuing to work with us as their products evolve. Identifying, negotiating and documenting relationships with additional strategic technology partners requires significant resources. Integrating third-party technology can be complex, costly and time-consuming. Third parties may be unwilling to build integrations. We may be required to devote additional resources to develop integrations for business applications on our own. Providers of business applications with which we have integrations may decide to compete with us or enter into arrangements with our competitors, resulting in such providers withdrawing support for our integrations. Any failure of our platform to operate effectively with business applications could reduce the demand for our platform, resulting in customer dissatisfaction and harm to our business. If we are unable to respond to these changes or failures in a cost-effective manner, our platform may become less marketable, less competitive, or obsolete, and our results of operations may be negatively impacted.

We have strategic technology partnerships with third parties that pay us a revenue share on their gross sales to our joint customers and/or collaborate to co-sell and co-market BigCommerce to new customers. Certain of

26

those strategic technology partners generate significant revenue for us, including PayPal, Google, and Stripe. While our contracts with strategic technology partners generally limit the ability of such partners to terminate the contract for convenience on short notice, certain of our strategic technology partners have termination for convenience clauses in their contracts with us. If our relationships with our strategic technology partners are disrupted, we may receive less revenue and incur costs to form other revenue-generating strategic technology partnerships. If our strategic technology partners were to be acquired by a competitor or were to acquire a competitor, it could compromise these relationships. This could harm our relationship with our customers, our reputation and brand, and our business and results of operations.

We are unable to track revenue-sharing on a real-time basis for some strategic technology partners, which can lead to delays and inaccuracies in reporting in accounting and revenue. In the past we have had, and could have in the future, disagreements with certain of our strategic technology partners on the amount of revenue share we are owed. Our forecasts for revenue-sharing arrangements and collaborations may be inaccurate. If we fail to accurately forecast the amount of revenue generated from our strategic technology partner relationships, our business and results of operations may be negatively impacted.

We leverage the sales and referral resources of agency and referral partners through a variety of programs. If we are unable to effectively utilize, maintain and expand these relationships, our revenue growth would slow, we would need to devote additional resources to the development, sales, and marketing of our platform, and our financial results and future growth prospects would be harmed. Our referral partners may demand greater referral fees or commissions.

We have a limited operating history, which makes it difficult to forecast our future results of operations.

We launched in 2009 and in 2015 expanded our strategic focus to include mid-market and large enterprise customers. We have a limited operating history and limited time implementing our strategic focus on the mid-market and large enterprise segments. As a result, our ability to accurately forecast our future results of operations is limited and subject to a number of uncertainties, including our ability to plan for and model future growth. The market for our ecommerce platform is relatively new and evolving, which makes our business and future prospects difficult to evaluate. It is difficult to predict customer demand for our platform, customer retention and expansion rates, the size and growth rate of the market, the entry of competitive products, or the success of existing competitive products. Our historical revenue growth should not be considered indicative of our future performance. In future periods, our revenue growth could slow or our revenue could decline for a number of reasons, including slowing demand for our services, increasing competition, changing technology, decreasing growth of our market, or our failure, for any reason, to take advantage of growth opportunities. We will continue to encounter risks and uncertainties frequently experienced by growing companies in rapidly changing industries. If our assumptions regarding these risks, uncertainties, or future revenue growth are incorrect, or if we do not address these risks successfully, our operating and financial results could differ materially from our expectations, and our business could suffer.

The estimates of market opportunity and forecasts of market growth included in this prospectus may prove to be inaccurate. Even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.

The market for ecommerce solutions is relatively new and will experience changes over time. Ecommerce market estimates and growth forecasts are uncertain and based on assumptions and estimates that may be inaccurate. Our addressable market depends on a number of factors, including businesses’ desire to differentiate themselves through ecommerce, partnership opportunities, changes in the competitive landscape, technological changes, data security or privacy concerns, customer budgetary constraints, changes in business practices, changes in the regulatory environment, and changes in economic conditions. Our estimates and forecasts relating to the size and expected growth of our market may prove to be inaccurate and our ability to produce accurate estimates and forecasts may be impacted by the economic uncertainty associated with the COVID-19 pandemic.

27

Even if the market in which we compete meets the size estimates and growth forecasted in this prospectus, our business could fail to grow at similar rates, if at all.

If we fail to manage our growth effectively, we may be unable to execute our business plan, maintain high levels of service and customer satisfaction or adequately address competitive challenges.

We may continue to experience rapid growth and organizational change, which may continue to place significant demands on our management and our operational and financial resources. We have also experienced growth in the number of customers, the amount of transactions we process, and the amount of data that our hosting infrastructure supports. Our success will depend in part on our ability to manage this growth effectively. We will require significant capital expenditures and valuable management resources to grow without undermining our culture of innovation, teamwork, and attention to customer success, which has been central to our growth so far. If we fail to manage our anticipated growth and change in a manner that preserves our corporate culture, it could negatively affect our reputation and ability to retain and attract customers and employees.

We intend to expand our international operations in the future. Our expansion will continue to place a significant strain on our managerial, administrative, financial, and other resources. If we are unable to manage our growth successfully, our business and results of operations could suffer.

It is important that we maintain a high level of customer service and satisfaction as we expand our business. As our customer base continues to grow, we will need to expand our account management, customer service, and other personnel. Failure to manage growth could result in difficulty or delays in launching our platform, declines in quality or customer satisfaction, increases in costs, difficulties in introducing new features, or other operational difficulties. Any of these could adversely impact our business performance and results of operations.

Failure to effectively develop and expand our marketing and sales capabilities could harm our ability to increase our customer base and achieve broader market acceptance of our platform. If we are not able to generate traffic to our website through digital marketing our ability to attract new customers may be impaired.

Our ability to increase our customer base and achieve broader market acceptance of our ecommerce platform will depend on our ability to expand our marketing and sales operations. We plan to continue expanding our sales force and strategic partners, both domestically and internationally. We also plan to dedicate significant resources to sales and marketing programs, including search engine and other online advertising. The effectiveness of our online advertising may continue to vary due to competition for key search terms, changes in search engine use, and changes in search algorithms used by major search engines and other digital marketing platforms. Our business and operating results will be harmed if our sales and marketing efforts do not generate a corresponding increase in revenue. We may not achieve anticipated revenue growth from expanding our sales force if we are unable to hire, develop, and retain talented sales personnel, if our new sales personnel are unable to achieve desired productivity levels in a reasonable period of time, or if our sales and marketing programs are not effective.

If the cost of marketing our platform over search engines or other digital marketing platforms increases, our business and operating results could be adversely affected. Competitors also may bid on the search terms that we use to drive traffic to our website. Such actions could increase our marketing costs and result in decreased traffic to our website.

Furthermore, search engines and digital marketing platforms may change their advertising policies from time to time. If these policies delay or prevent us from advertising through these channels, it could result in reduced traffic to our website and subscriptions to our platform. New search engines and other digital marketing platforms may develop, particularly in specific jurisdictions, that reduce traffic on existing search engines and digital marketing platforms. If we are not able to achieve prominence through advertising or otherwise, we may

28

not achieve significant traffic to our website through these new platforms and our business and operating results could be adversely affected.

To the extent our security measures are compromised, our platform may be perceived as not being secure. This may result in customers curtailing or ceasing their use of our platform, our reputation being harmed, our incurring significant liabilities, and adverse effects on our results of operations and growth prospects.

Our operations involve the storage and transmission of customer and shopper data or information. Cyberattacks and other malicious internet-based activity continue to increase, and cloud-based platform providers of services are expected to continue to be targeted. Threats include traditional computer “hackers,” malicious code (such as viruses and worms), employee theft or misuse and denial-of-service attacks. Sophisticated nation-states and nation-state supported actors now engage in such attacks, including advanced persistent threat intrusions. Despite significant efforts to create security barriers to such threats, it is virtually impossible for us to entirely mitigate these risks. If our security measures are compromised as a result of third-party action, employee or customer error, malfeasance, stolen or fraudulently obtained log-in credentials, or otherwise, our reputation could be damaged, our business may be harmed, and we could incur significant liability. We may be unable to anticipate or prevent techniques used to obtain unauthorized access or to compromise our systems because they change frequently and are generally not detected until after an incident has occurred. As we rely on third-party and public-cloud infrastructure, we will depend in part on third-party security measures to protect against unauthorized access, cyberattacks, and the mishandling of customer data. A cybersecurity event could have significant costs, including regulatory enforcement actions, litigation, litigation indemnity obligations, remediation costs, network downtime, increases in insurance premiums, and reputational damage. Many companies that provide cloud-based services have reported a significant increase in cyberattack activity since the beginning of the COVID-19 pandemic.

We depend on third-party data hosting and transmission services. Increases in cost, interruptions in service, latency, or poor service from our third-party data center providers could impair the delivery of our platform. This could result in customer or shopper dissatisfaction, damage to our reputation, loss of customers, limited growth, and reduction in revenue.

We currently serve the majority of our platform functions from third-party data center hosting facilities operated by Google Cloud Platform, located in Iowa. We serve ancillary functions for our customers from third-party data center hosting facilities operated by Amazon Web Services, located in Virginia. Our platform is deployed to multiple data centers within these geographies, with additional geographies available for disaster recovery. Our operations depend, in part, on our third-party providers’ protection of these facilities from natural disasters, power or telecommunications failures, criminal acts, or similar events (such as the COVID-19 pandemic). If any third-party facility’s arrangement is terminated, or its service lapses, we could experience interruptions in our platform, latency, as well as delays and additional expenses in arranging new facilities and services.

A significant portion of our operating cost is from our third-party data hosting and transmission services. If the costs for such services increase due to vendor consolidation, regulation, contract renegotiation or otherwise, we may not be able to increase the fees for our ecommerce platform or professional services to cover the changes. As a result, our operating results may be significantly worse than forecasted. Our servers may be unable to achieve or maintain data transmission capacity sufficient for timely service of increased traffic or order processing. Our failure to achieve or maintain sufficient and performant data transmission capacity could significantly reduce demand for our platform.

Our customers often draw many shoppers over short periods of time, including from new product releases, holiday shopping seasons and flash sales. These events significantly increase the traffic on our servers and the volume of transactions processed on our platform. Despite precautions taken at our data centers, spikes in usage volume, or a natural disaster, an act of terrorism, vandalism or sabotage, closure of a facility without adequate

29

notice, or other unanticipated problems (such as the COVID-19 pandemic) could result in lengthy interruptions or performance degradation of our platform. Any damage to, or failure of, the systems of our third-party providers could result in interruptions to our platform. Even with current and planned disaster recovery arrangements, our business could be harmed. If we experience damage or interruption, our insurance policies may not adequately compensate us for any losses that we may incur. These factors in turn could further reduce our revenue, subject us to liability, cause us to issue credits, or cause customers to terminate their subscriptions, any of which could materially adversely affect our business.

If there are interruptions or performance problems associated with our technology or infrastructure, our existing customers may experience service outages, and our new customers may experience delays in using our platform.

Our continued growth depends, in part, on the ability of our existing and potential customers to access our platform 24 hours a day, seven days a week, without interruption or performance degradation. We have experienced and may, in the future, experience disruptions, data loss, outages, and other performance problems with our infrastructure. These can be due to a variety of factors, including infrastructure changes, introductions of new functionality, human or software errors, capacity constraints, denial-of-service attacks, or other security-related incidents, any of which may be recurring. As we continue to add customers, expand geographically, and enhance our platform’s functionality, the additional scale may increase complexity and our average uptime for future periods may decrease. We may not be able to identify the cause or causes of these performance problems promptly. If our platform is unavailable or if our customers are unable to access our platform within a reasonable amount of time, our business would be harmed. Any outage on our platform would impair the ability of our customers to engage in ecommerce, which would negatively impact our brand, reputation and customer satisfaction. We provide service credits to our customers for downtime they experience using our platform. Any downtime or malfunction could require us to issue a significant amount of service credits to customers. At times, we issue service credits to customers that we are not able to identify as having been affected by an incident. Issuing a significant amount of service credits would negatively impact our financial position. We depend on services from various third parties to maintain our infrastructure and any disruptions to these services, including from causes outside our control, would significantly impact our platform. In the future, these services may not be available to us on commercially reasonable terms, or at all. Loss of any of these services could decrease our platform’s functionality until we develop equivalent technology or, if equivalent technology is available from another party, we identify, obtain, and integrate it into our infrastructure. If we do not accurately predict our infrastructure capacity requirements, our customers could experience service shortfalls. We may also be unable to address capacity constraints, upgrade our systems, and develop our technology and network architecture to accommodate actual and anticipated technology changes.

Any of the above circumstances or events may harm our reputation, cause customers to terminate their agreements with us, impair our ability to grow our customer base, subject us to financial liabilities under our SLAs, and otherwise harm our business, results of operations, and financial condition.

We anticipate that our operations will continue to increase in complexity as we grow, which will create management challenges.

Our business has experienced strong growth and is complex. We expect this growth to continue and for our operations to become increasingly complex. To manage this growth, we continue to make substantial investments to improve our operational, financial, and management controls as well as our reporting systems and procedures. We may not be able to implement and scale improvements to our systems and processes in a timely or efficient manner or in a manner that does not negatively affect our operating results. For example, we may not be able to effectively monitor certain extraordinary contract requirements or individually negotiated provisions as the number of transactions continues to grow. Our systems and processes may not prevent or detect all errors, omissions, or fraud. We may have difficulty managing improvements to our systems, processes and controls or in connection with third-party software. This could impair our ability to provide our platform to our customers,

30

causing us to lose customers, limiting our platform to less significant updates, or increasing our technical support costs. If we are unable to manage this complexity, our business, operations, operating results and financial condition may suffer.

As our customer base continues to grow, we will need to expand our services and other personnel, and maintain and enhance our partnerships, to provide a high level of customer service. Extended stay-at-home, business closure, and other restrictive orders may impact our ability to identify, hire, and train new personnel. We also will need to manage our sales processes as our sales personnel and partner network continue to grow and become more complex, and as we continue to expand into new geographies and market segments. If we do not effectively manage this increasing complexity, the quality of our platform and customer service could suffer, and we may not be able to adequately address competitive challenges. These factors could impair our ability to attract and retain customers and expand our customers’ use of our platform.

We depend on our senior management team and the loss of one or more key employees or an inability to attract and retain highly skilled employees could adversely affect our business.

Our success depends largely upon the continued services of our executive officers. We rely on our leadership team for research and development, marketing, sales, services, and general and administrative functions, and on mission-critical individual contributors. From time to time, our executive management team may change from the hiring or departure of executives, which could disrupt our business. We do not have employment agreements with our executive officers or other key personnel that require them to continue to work for us for any specified period; therefore, they could terminate their employment with us at any time. The loss of one or more of our executive officers or key employees (including any limitation on the performance of their duties or short term or long term absences as a result of COVID-19) could have a serious adverse effect on our business.

To execute our growth plan, we must attract and retain highly qualified personnel. Competition for these personnel is intense, especially for experienced software engineers and senior sales executives. If we are unable to attract such personnel in cities where we are located, we may need to hire in other locations, which may add to the complexity and costs of our business operations. We expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Extended stay-at-home, business closure, and other restrictive orders may impact our ability to identify, hire, and train new personnel. Many of the companies with which we compete for experienced personnel have greater resources than we have. If we hire employees from competitors or other companies, their former employers may attempt to assert that these employees or BigCommerce have breached legal obligations, resulting in a diversion of our time and resources. In addition, job candidates and existing employees often consider the value of the stock awards they receive in connection with their employment. If the perceived value of our stock awards declines, it may adversely affect our ability to recruit and retain highly skilled employees. If we fail to attract new personnel or fail to retain and motivate our current personnel, it could adversely affect our business and future growth prospects.

If we are unable to maintain our corporate culture as we grow, we could lose the innovation, teamwork, passion and focus on execution that we believe contribute to our success, and our business may be harmed.

We believe a critical component to our success has been our corporate culture. We have invested substantial time and resources in building our team. As we grow and develop the infrastructure of a public company, our operations may become increasingly complex. We may find it difficult to maintain these important aspects of our corporate culture. If we are required to maintain work-from-home arrangements for a significant period of time, it may impact our ability to preserve our corporate culture. Any failure to preserve our culture could negatively affect our future success, including our ability to retain and recruit personnel, and to effectively focus on and pursue our corporate objectives.

We may need to reduce or change our pricing model to remain competitive.

We price our subscriptions based on a combination of GMV order volume, and feature functionality. We expect that we may need to change our pricing from time to time. As new or existing competitors introduce

31

products that compete with ours or reduce their prices, we may be unable to attract new customers or retain existing customers. We also must determine the appropriate price to enable us to compete effectively internationally. Mid-market and large enterprise customers may demand substantial price discounts as part of the negotiation of sales contracts. As a result, we may be required or choose to reduce our prices or otherwise change our pricing model, which could adversely affect our business, operating results, and financial condition.

Our sales cycle with mid-market and large enterprise customers can be long and unpredictable, and our sales efforts require considerable time and expense.

The timing of our sales with our mid-market and large enterprise customers and related revenue recognition is difficult to predict because of the length and unpredictability of the sales cycle for these customers. Mid-market and large enterprise customers, particularly those in highly regulated industries and those requiring customized applications, may have a lengthy sales cycle for the evaluation and implementation of our platform. If these customers maintain work-from-home arrangements for a significant period of time, it may cause a lengthening of these sales cycles. This may cause a delay between increasing operating expenses for such sales efforts and, upon successful sales, the generation of corresponding revenue. We are often required to spend significant time and resources to better educate our potential mid-market and large enterprise customers and familiarize them with the platform. The length of our sales cycle for these customers, from initial evaluation to contract execution, is generally three to six months but can vary substantially. On occasion, some customers will negotiate their contracts to include a trial period, delayed payment or a number of months on a promotional basis.

As the purchase and launch of our platform can be dependent upon customer initiatives, infrequently, our sales cycle can extend to up to twelve months. As a result, much of our revenue is generated from the recognition of contract liabilities from contracts entered into during previous periods. Customers often view a subscription to our ecommerce platform and services as a strategic decision with significant investment. As a result, customers frequently require considerable time to evaluate, test, and qualify our platform prior to entering into or expanding a subscription. During the sales cycle, we expend significant time and money on sales and marketing and contract negotiation activities, which may not result in a sale. Additional factors that may influence the length and variability of our sales cycle include:

Given these factors, it is difficult to predict whether and when a sale will be completed, and when revenue from a sale will be recognized. Consequently, a shortfall in demand for our solutions and services or a decline in new or renewed contracts in a given period may not significantly reduce our revenue for that period but could negatively affect our revenue in future periods.

If we fail to maintain or grow our brand recognition, our ability to expand our customer base will be impaired and our financial condition may suffer.

We believe maintaining and growing the BigCommerce brand is important to supporting continued acceptance of our existing and future solutions, attracting new customers to our platform, and retaining existing

32

customers. We also believe that the importance of brand recognition will increase as competition in our market increases. Successfully maintaining our brand will depend largely on the effectiveness of our marketing efforts, our ability to provide a reliable and useful platform to meet the needs of our customers at competitive prices, our ability to maintain our customers’ trust, our ability to continue to develop new functionality and solutions, and our ability to successfully differentiate our platform. Additionally, our partners’ performance may affect our brand and reputation if customers do not have a positive experience. Brand promotion activities may not generate customer awareness or yield increased revenue. Even if they do, any increased revenue may not offset the expenses we incurred in building our brand. If we fail to successfully promote and maintain our brand, we may fail to attract enough new customers or retain our existing customers to realize a sufficient return on our brand-building efforts, and our business could suffer.

If we fail to offer high quality support, our business and reputation could suffer.

Our customers rely on our personnel for support related to our subscription and customer solutions. High-quality support is important for the renewal and expansion of our agreements with existing customers. The importance of high-quality support will increase as we expand our business and pursue new customers, particularly mid-market and large enterprise customers. If we do not help our customers quickly resolve issues and provide effective ongoing support, our ability to sell new software to existing and new customers could suffer and our reputation with existing or potential customers could be harmed.

We store personal information of our customers and their shoppers. If the security of this information is compromised or is otherwise accessed without authorization, our reputation may be harmed and we may be exposed to liability and loss of business.

We transmit or store personal information, credit card information and other confidential information of our partners, our customers, and their shoppers. Third-party applications available on our platform and mobile applications may also store personal information, credit card information, and other confidential information. We do not proactively monitor the content that our customers upload or the information provided to us through the applications integrated with our ecommerce platform; therefore, we do not control the substance of the content on our servers, which may include personal information.

We use third-party service providers and subprocessors to help us deliver services to customers and their shoppers. These service providers and subprocessors may store personal information, credit card information and/or other confidential information. Such information may be the target of unauthorized access or subject to security breaches as a result of third-party action, employee error, malfeasance or otherwise. Many companies that provide these services have reported a significant increase in cyberattack activity since the beginning of the COVID-19 pandemic. Any of these could (a) result in the loss of information, litigation, indemnity obligations, damage to our reputation and other liability, or (b) have a material adverse effect on our business, financial condition, and results of operations.

Because the techniques used to obtain unauthorized access or sabotage systems change frequently and generally are not identified until they are launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Even if such a data breach did not arise out of our action or inaction, or if it were to affect one or more of our competitors or our customers’ competitors, rather than us, the resulting concern could negatively affect our customers and our business. Concerns regarding data privacy and security may cause some of our customers to stop using our platform and fail to renew their subscriptions. In addition, failures to meet our customers’ or shoppers’ expectations with respect to security and confidentiality of their data and information could damage our reputation and affect our ability to retain customers, attract new customers, and grow our business.

Our failure to comply with legal or contractual requirements around the security of personal information could lead to significant fines and penalties, as well as claims by our customers, their shoppers, or other

33

stakeholders. These proceedings or violations could force us to spend money in defense or settlement of these proceedings, result in the imposition of monetary liability or injunctive relief, divert management’s time and attention, increase our costs of doing business, and materially adversely affect our reputation and the demand for our platform.

If our security measures fail to protect credit card information adequately, we could be liable to our partners, the payment card associations, our customers, their shoppers and consumers with whom we have a direct relationship. We could be subject to fines and higher transaction fees, we could face regulatory or other legal action, and our customers could end their relationships with us. The limitations of liability in our contracts may not be enforceable or adequate or would otherwise protect us from any such liabilities or damages with respect to any particular claim.

Our insurance coverage, including coverage for errors and omissions, may not continue to be available on acceptable terms or may not be available in sufficient amounts to cover one or more large claims. Our insurers could deny coverage as to any future claim. The successful assertion of one or more large claims against us, or changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have an adverse effect on our business, financial condition, and results of operations.

We are also subject to federal, state, and foreign laws regarding cybersecurity and the protection of data. Many jurisdictions have enacted laws requiring companies to notify individuals of security breaches involving certain types of personal information. Our agreements with certain customers and partners require us to notify them of certain security incidents. Some jurisdictions and customers require us to safeguard personal information or confidential information using specific measures. If we fail to observe these requirements, our business, operating results, and financial condition could be adversely affected.

Evolving global internet laws, regulations and standards, privacy regulations, cross-border data transfer restrictions, and data localization requirements may limit the use and adoption of our services, expose us to liability, or otherwise adversely affect our business.

Federal, state, or foreign governmental bodies or agencies have in the past adopted, and may in the future adopt, laws and regulations affecting the use of the internet as a commercial medium. These laws and regulations could impact taxation, internet neutrality, tariffs, content, copyrights, distribution, electronic contracts and other communications, consumer protection, and the characteristics and quality of services. Legislators and regulators may make legal and regulatory changes, or apply existing laws, in ways that require us to incur substantial costs, expose us to unanticipated civil or criminal liability, or cause us to change our business practices. These laws and regulations and resulting increased costs could materially harm our business, results of operations, and financial condition.

Laws and regulations governing data privacy are constantly evolving. Many of these laws and regulations, including the European Union’s GDPR and the California Consumer Protection Act (the “CCPA”), contain detailed requirements regarding collecting and processing personal information, restrict the use and storage of such information, and govern the effectiveness of consumer consent. They could restrict our ability to store and process personal data (in particular, our ability to use certain data for purposes such as risk or fraud avoidance, marketing or advertising), to control our costs by using certain vendors or service providers, and to offer certain services in certain jurisdictions. Further, the CCPA requires covered companies to provide new disclosures to California consumers, provide such consumers new ways to opt-out of certain sales of personal information, and allow for a new cause of action for data breaches. Such laws could restrict our customers’ ability to run their businesses; for example, by limiting their ability to effectively market to interested shoppers. This could reduce our revenue and the general demand for our services.

Such laws and regulations are often inconsistent and may be subject to amendment or re-interpretation, which may cause us to incur significant costs and expend significant effort to ensure compliance. For example, the European Court of Justice recently invalidated the U.S.-EU Privacy Shield as a basis for transfers of personal

34

data from the EU to the U.S. while upholding standard contractual clauses as a mechanism for transfers. Our response to these requirements globally may not meet the expectations of individual customers, their shoppers, or other stakeholders, which could reduce the demand for our services. Some customers or other service providers may respond to these evolving laws and regulations by asking us to make certain privacy or data-related contractual commitments that we are unable or unwilling to make. This could lead to the loss of current or prospective customers or other business relationships.

Certain laws and regulations, like the GDPR, also include restrictions on the transfer of personal information across national borders. Because our services are accessible worldwide, certain foreign jurisdictions may claim that we are required to comply with such laws even in jurisdictions where we have no local entity, employees or infrastructure. Some of these laws include strict localization provisions that require certain data to be stored within a particular region or jurisdiction. We rely on a globally distributed infrastructure in order to be able to provide our services efficiently, and consequently may not be able to meet the expectations of customers who are located in or otherwise subject to such localization requirements, which may reduce the demand for our services.

Our failure to comply with these and additional laws or regulations could expose us to significant fines and penalties imposed by regulators, as well as legal claims by our customers, or their shoppers, or other relevant stakeholders. Similarly, many of these laws require us to maintain an online privacy policy and terms of service that disclose our practices regarding the collection, processing, and disclosure of personal information. If these disclosures contain any information that a court or regulator finds to be inaccurate or inadequate, we could also be exposed to legal or regulatory liability. Any such proceedings or violations could force us to spend money in defense or settlement, result in the imposition of monetary liability or demanding injunctive relief, divert management’s time and attention, increase our costs of doing business, and materially adversely affect our reputation.

Mobile devices are increasingly being used to conduct commerce, and if our platform does not operate as effectively when accessed through these devices, our customers and their shoppers may not be satisfied with our services, which could harm our business.

Ecommerce transacted over mobile devices continues to grow more rapidly than desktop transactions. We are dependent on the interoperability of our platform with third-party mobile devices and mobile operating systems as well as web browsers that are out of our control. Changes in such devices, systems, or web browsers that degrade the functionality of our platform or give preferential treatment to competitive services could adversely affect usage of our platform. Mobile ecommerce is a key element in our strategy and effective mobile functionality is integral to our long-term development and growth strategy. If our customers and their shoppers have difficulty accessing and using our platform on mobile devices, our business and operating results could be adversely affected.

Activities of customers, their shoppers, and our partners could damage our brand, subject us to liability and harm our business and financial results.

Our terms of service prohibit our customers from using our platform to engage in illegal activities and our terms of service permit us to take down a customer’s shop if we become aware of illegal use. Customers may nonetheless engage in prohibited or illegal activities or upload store content in violation of applicable laws, which could subject us to liability. Our partners may engage in prohibited or illegal activities, which could subject us to liability. Furthermore, our brand may be negatively impacted by the actions of customers or partners that are deemed to be hostile, offensive, inappropriate, or illegal. We do not proactively monitor or review the appropriateness of the content of our customers’ stores or our partners’ activities. Our safeguards may not be sufficient for us to avoid liability or avoid harm to our brand. Hostile, offensive, inappropriate, or illegal use could adversely affect our business and financial results.

In many jurisdictions, laws relating to the liability of providers of online services for activities of their shoppers and other third parties are being tested by actions based on defamation, invasion of privacy, unfair

35

competition, copyright and trademark infringement, and other theories. Any court ruling or other governmental regulation or action that imposes liability on customers of online services in connection with the activities of their shoppers could harm our business. We could also be subject to liability under applicable law, which may not be fully mitigated by our terms of service. Any liability attributed to us could adversely affect our brand, reputation, ability to expand our subscriber base, and financial results.

Unfavorable conditions in our industry or the global economy, or reductions in IT spending, could limit our ability to grow our business and negatively affect our results of operations.

Our results of operations may vary based on the impact of changes in our industry or the global economy on us or our customers. The revenue growth and potential profitability of our business depend on demand for our platform. Current or future economic uncertainties or downturns could adversely affect our business and results of operations. Negative conditions in the global economy or individual markets, including changes in gross domestic product growth, financial and credit market fluctuations, political turmoil, natural catastrophes, warfare and terrorist attacks on the United States, Europe, Australia, the Asia Pacific region or elsewhere, could cause a decrease in business investments, including spending on IT and negatively affect our business. In particular, given our investment in our development capabilities in Ukraine, political turmoil, warfare, or terrorist attacks in Ukraine could negatively affect our business.

To the extent our platform is perceived by customers and potential customers as costly, or too difficult to launch or migrate to, it would negatively affect our growth. Our revenue may be disproportionately affected by delays or reductions in general IT spending. Competitors, many of whom are larger and more established than we are, may respond to market conditions by lowering prices and attempting to lure away our customers. In addition, consolidation in certain industries may result in reduced overall spending on our platform. We cannot predict the timing, strength, or duration of any economic slowdown, instability or recovery, generally or within any particular industry. If the economic conditions of the general economy or markets in which we operate worsen from present levels, our business, results of operations and financial condition could be adversely affected.

Natural catastrophic events and man-made problems such as power disruptions, computer viruses, global pandemics, data security breaches and terrorism may disrupt our business.

We rely heavily on our network infrastructure and IT systems for our business operations. An online attack, earthquake, fire, terrorist attack, power loss, global pandemics (such as the COVID-19 pandemic), telecommunications failure, or other similar catastrophic event could cause system interruptions, delays in accessing our service, reputational harm, and loss of critical data. Such events could prevent us from providing our platform to our customers. A catastrophic event that results in the destruction or disruption of our data centers, or our network infrastructure or IT systems, including any errors, defects, or failures in third-party hardware, could affect our ability to conduct normal business operations, and adversely affect our operating results.

In addition, as computer malware, viruses, computer hacking, fraudulent use attempts, and phishing attacks have become more prevalent, we face increased risk from these activities. These activities threaten the performance, reliability, security, and availability of our platform. Any computer malware, viruses, computer hacking, fraudulent use attempts, phishing attacks, or other data security breaches to our systems could, among other things, harm our reputation and our ability to retain existing customers and attract new customers. Many companies that provide cloud-based services have reported a significant increase in cyberattack activity since the beginning of the COVID-19 pandemic.

We could incur substantial costs in protecting or defending our proprietary rights. Failure to adequately protect our rights could impair our competitive position. We could lose valuable assets, experience reduced revenue, and incur costly litigation.

Our success is dependent, in part, upon protecting our proprietary technology. We rely on a combination of trade secret laws, contractual provisions, trademarks, service marks, copyrights, and patents in an effort to

36

establish and protect our proprietary rights. However, the steps we take to protect our intellectual property may be inadequate. While we have been issued a patent in the United States and have an additional patent application pending, we may be unable to obtain patent protection for the technology covered in our patent application. We make business decisions about when to seek patent protection for a particular technology and when to rely upon trade secret protection. The approach we select may ultimately prove to be inadequate.

Our patent or patents issued in the future may not provide us with competitive advantages, or may be successfully challenged by third parties. Any of our patents, trademarks, or other intellectual property rights may be challenged or circumvented by others or invalidated through administrative process or litigation. Others may independently develop similar products, duplicate any of our solutions or design around our patents, or adopt similar or identical brands for competing platforms. Legal standards relating to the validity, enforceability, and scope of protection of intellectual property rights are uncertain. Despite our precautions, it may be possible for unauthorized third parties to copy our platform and use information that we regard as proprietary to create products and services that compete with ours. Some license provisions restricting unauthorized use, copying, transfer, and disclosure of our intellectual property may be unenforceable under the laws of jurisdictions outside the United States.

To the extent we expand our international activities, our exposure to unauthorized copying and use of our platform and proprietary information may increase. Moreover, effective trademark, copyright, patent, and trade secret protection may not be available or commercially feasible in every country in which we conduct business. Further, intellectual property law, including statutory and case law, particularly in the United States, is constantly developing. Changes in the law could make it harder for us to enforce our rights.

We enter into confidentiality and invention assignment agreements with our employees and consultants. We enter into confidentiality agreements with strategic and business partners. These agreements may not be effective in controlling access to and distribution of our proprietary information. These agreements do not prevent our competitors or partners from independently developing technologies that are equivalent or superior to our platform.

We may be required to spend significant resources to monitor, protect, and enforce our intellectual property rights. Litigation may be necessary in the future to enforce our intellectual property rights and protect our trade secrets. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming, and distracting to management. Such litigation could result in the impairment or loss of portions of our intellectual property. Enforcement of our intellectual property rights may be met with defenses, counterclaims, and countersuits attacking the validity and enforceability of our intellectual property. An adverse determination of any litigation proceedings could put our intellectual property at risk of being invalidated or interpreted narrowly. An adverse determination could risk the issuance or cancellation of pending patent and trademark filings. Because of the substantial discovery required in connection with intellectual property litigation, our confidential or sensitive information could be compromised by disclosure in litigation. Litigation could result in public disclosure of results of hearings, motions, or other interim developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our Series 1 common stock.

Our inability to protect our proprietary technology against unauthorized copying or use, as well as any costly litigation or diversion of our management’s attention and resources, could delay further sales or the implementation of our platform, impair the functionality of our platform, delay introductions of new functionality to our platform, result in the substitution of inferior or more costly technologies into our platform, or injure our reputation. We will not be able to protect our intellectual property if we are unable to enforce our rights or if we do not detect unauthorized use of our intellectual property. Policing unauthorized use of our technologies, trade secrets, and intellectual property may be difficult, expensive, and time-consuming, particularly in foreign countries where the laws may not be as protective of intellectual property rights as those in the United States and where mechanisms for enforcement of intellectual property rights may be weak. If we fail to meaningfully

37

protect our intellectual property and proprietary rights, our business, operating results, and financial condition could be adversely affected.

We have been, and may in the future be, subject to legal proceedings and litigation, including intellectual property disputes, which are costly and may subject us to significant liability and increased costs of doing business. Our business may suffer if it is alleged or determined that our technology infringes the intellectual property rights of others.

The software industry is characterized by the existence of a large number of patents, copyrights, trademarks, trade secrets, and other intellectual and proprietary rights. Companies in the software industry are often required to defend against litigation claims based on allegations of infringement or other violations of intellectual property rights. Our technologies may not be able to withstand any third-party claims or rights against their use. These lawsuits are time-consuming and expensive to resolve and they divert management’s time and attention. Our future success depends in part on not infringing the intellectual property rights of others.

Many software companies have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them. Any litigation may also involve patent holding companies or other adverse patent owners that have no relevant product revenue and against which our patent may therefore provide little or no deterrence. We have and may in the future need to enter into settlement agreements that require us to pay settlement fees and that encumber a portion of our intellectual property. Any claims or litigation could cause us to incur significant expenses and, whether or not successfully asserted against us, could require that we pay substantial damages, ongoing royalty or license payments, require us to re-engineer all or a portion of our platform, or require that we comply with other unfavorable terms. If a third party is able to obtain an injunction preventing us from accessing third-party intellectual property rights, or if we cannot license or develop technology for any infringing aspect of our business, we would be forced to limit or stop sales of our software or cease business activities covered by such intellectual property. It could prevent us from competing effectively.

We may be contractually obligated to indemnify our customers for infringement of a third party’s intellectual property rights. Responding to such claims regardless of their merit, can be time-consuming, costly to defend in litigation, and damage our reputation and brand. We also may be required to redesign our platform, delay releases, enter into costly settlement or license agreements, pay costly damage awards, or face a temporary or permanent injunction prohibiting us from marketing or selling our platform. Requiring us to change one or more aspects of the way we deliver our platform may harm our business.

Although we carry general liability insurance and other insurance, our insurance may not cover potential claims of this type. Our insurance may not be adequate to cover us for all liability that may be imposed. We may not be able to maintain our insurance coverage. We cannot predict the outcome of lawsuits, and cannot assure you that the results of any of these actions will not have an adverse effect on our business, operating results or financial condition.

Indemnity provisions in various agreements potentially expose us to substantial liability for intellectual property infringement, data protection, and other losses.

Some of our agreements with customers and other third parties include indemnification provisions under which we agree to indemnify them for losses suffered or incurred as a result of claims of intellectual property infringement, data protection, damages to property or persons, or other liabilities relating to or arising from our platform, services or other contractual obligations. Some of these indemnity agreements provide for uncapped liability for which we would be responsible, and some indemnity provisions survive termination or expiration of the applicable agreement. Large indemnity payments could harm our business, results of operations and financial condition. Although we normally contractually limit our liability with respect to such obligations, we may still incur substantial liability related to them and we may be required to cease use of certain functions of our platform

38

or services as a result of any such claims. Any dispute with a customer with respect to such obligations could have adverse effects on our relationship with that customer, other existing customers, and new customers. Such a dispute could harm our business and results of operations.

We rely on third-party proprietary and open source software for our platform. Our inability to obtain third-party licenses for such software, or obtain them on favorable terms, or any errors or failures caused by such software could adversely affect our business, results of operations and financial condition.

Some of our offerings include software or other intellectual property licensed from third parties. It may be necessary in the future to renew licenses relating to various aspects of these applications or to seek new licenses for existing or new applications. Necessary licenses may not be available on acceptable terms or under open source licenses permitting redistribution in commercial offerings, if at all. Our inability to obtain certain licenses or other rights or to obtain such licenses or rights on favorable terms could result in delays in product releases until equivalent technology can be identified, licensed or developed, if at all, and integrated into our platform. It may have a material adverse effect on our business, results of operations and financial condition. Third parties may allege that additional licenses are required for our use of their software or intellectual property. We may be unable to obtain such licenses on commercially reasonable terms or at all. The inclusion in our offerings of software or other intellectual property licensed from third parties on a non-exclusive basis could limit our ability to differentiate our offerings from those of our competitors. To the extent that our platform depends upon the successful operation of third-party software, any undetected errors or defects in such third-party software could impair the functionality of our platform, delay new feature introductions, result in a failure of our platform, and injure our reputation.

Our use of open source software could subject us to possible litigation or cause us to subject our platform to unwanted open source license conditions that could negatively impact our sales.

A significant portion of our platform incorporates open source software, and we expect to incorporate open source software into other offerings or solutions in the future. Such open source software is generally licensed by its authors or other third parties under open source licenses. Little legal precedent governs the interpretation of these licenses; therefore, the potential impact of these terms on our business is unknown and may result in unanticipated obligations regarding our technologies. If a distributor of open source software were to allege that we had not complied with its license, we could be required to incur significant legal expenses. If we combine our proprietary software with open source software or utilize open source software in a certain manner, under some open source licenses, we could be in breach of the license if we did not release the source code of our proprietary software. Releasing our source code could substantially help our competitors develop products that are similar to or better than ours.

If our platform fails to perform properly, and if we fail to develop enhancements to resolve performance issues, we could lose customers, become subject to performance or warranty claims, or incur significant costs.

Our operations are dependent upon our ability to prevent system interruption. The applications underlying our platform are inherently complex and may contain material defects or errors, which may cause disruptions in availability or other performance problems. Defects, errors, disruptions in service, cyber-attacks, or other performance problems with our software, whether in connection with the day-to-day operation, upgrades or otherwise, could result in: loss of customers; lost or delayed market acceptance and sales of our platform; delays in payment to us by customers; injury to our reputation and brand; legal claims, including warranty and service claims, against us; diversion of our resources, including through increased service and warranty expenses or financial concessions; and increased insurance costs.

We have found defects in our platform and may discover additional defects in the future that could result in data unavailability, unauthorized access to, loss, corruption, or other harm to our customers’ data. We may not be able to detect and correct defects or errors before release. Consequently, we or our customers may discover

39

defects or errors after our platform has been employed. We implement bug fixes and upgrades as part of our regularly scheduled system maintenance. If we do not complete this maintenance according to schedule or if customers are otherwise dissatisfied with the frequency and/or duration of our maintenance services and related system outages, customers could terminate their contracts, or delay or withhold payment to us, or cause us to issue credits, make refunds, or pay penalties. The costs incurred or delays resulting from the correction of defects or errors in our software or other performance problems may be substantial and could adversely affect our operating results.

Payment transactions on our ecommerce platform subject us to regulatory requirements, additional fees, and other risks that could be costly and difficult to comply with or that could harm our business.

We are required by our payment processors to comply with payment card network operating rules and we have agreed to reimburse our payment processors for any fees or fines they are assessed by payment card networks as a result of any rule violations by us or our customers. The payment card networks set and interpret the card rules. We face the risk that one or more payment card networks or other processors may, at any time, assess penalties against us, against our customers, or terminate our ability to accept credit card payments or other forms of online payments from shoppers. This would have an adverse effect on our business, financial condition, and operating results.

If we fail to comply with the payment card network rules, including the Payment Card Industry Data Security Standard (“PCI-DSS”) and those of each of the credit card brands, we would breach our contractual obligations to our payment processors, financial institutions, partners, and customers. Such a failure may subject us to fines, penalties, damages, higher transaction fees, and civil liability. It could prevent us from processing or accepting payment cards or lead to a loss of payment processor partners, even if customer or shopper information has not been compromised.

We provide our ecommerce platform to businesses in highly-regulated industries, which subjects us to a number of challenges and risks.

We provide our ecommerce platform to customers in highly regulated industries such as pharmaceuticals, insurance, healthcare and life sciences, and we may have customers in other highly-regulated industries in the future. Providing our ecommerce platform to such entities subjects us to a number of challenges and risks. Selling to such entities can be highly competitive, expensive, and time-consuming, often requiring significant upfront time and expense without any assurance that these efforts will generate a sale. Customers in highly-regulated industries may demand shorter subscription periods or other contract terms that differ from our standard arrangements, including terms that can lead those customers to obtain broader rights in our offerings than would be standard. Such entities may have statutory, contractual, or other legal rights to terminate contracts with us or our partners due to a default or for other reasons. Any such termination may adversely affect our reputation, business, results of operations and financial condition. Additionally, due to the heightened regulatory environment in which they operate, potential customers in these industries may encounter additional difficulties when trying to move away from legacy ecommerce platforms to an open SaaS platform like the one we provide.

Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.

As of December 31, 2019, we had accumulated federal and state net operating loss (“NOL”) carryforwards of $118.2 million and $37.3 million, respectively. The federal and state NOL carryforwards each will begin to expire in 2036. Certain of the federal losses have no expiration. As of December 31, 2019, we also had total foreign NOL carryforwards of $6.9 million, which do not expire under local law. In general, under Section 382 of the United States Internal Revenue Code of 1986, as amended (the “Code”), a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change NOLs to offset future taxable income. If we undergo an ownership change in connection with this offering, our ability to utilize NOLs could be limited by Section 382 of the Code. Future changes in our stock ownership, some of which are outside of our

40

control, could result in an ownership change under Section 382 of the Code. Furthermore, our ability to utilize NOLs of companies that we have acquired or may acquire in the future may be subject to limitations. Furthermore, our losses in Australia are subject to the change of ownership test rules in that jurisdiction that when applied may limit our ability to fully utilize our Australian NOLs. For these reasons, we may not be able to utilize a material portion of the NOLs, even if we were to achieve profitability.

The Tax Cuts and Jobs Act (the “TCJA”) was enacted on December 22, 2017 and significantly reformed the Code. The TCJA, among other things, generally eliminates the ability to carry back any NOLs to prior taxable years, while allowing post-2017 unused NOLs to be carried forward indefinitely. Recently enacted legislation, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), temporarily reverses the limitations imposed by the TCJA by permitting a corporation to offset without limitation its taxable income in 2019 or 2020 with NOL carryforwards generated in prior years. In addition, under the TCJA, as modified by the CARES Act, the amount of NOLs that we are permitted to deduct in any taxable year beginning after December 31, 2020, is limited to 80% of our taxable income in such year, where taxable income is determined without regard to the NOL deduction itself. It is uncertain if and to what extent various states will conform to the TCJA or the CARES Act. The changes in the carryforward/carryback periods as well as the limitation on use of NOLs in the taxable years beginning after December 31, 2020 may affect our ability to fully utilize our available NOLs.

We may be subject to additional obligations to collect and remit sales tax and other taxes. We may be subject to tax liability for past sales, which could harm our business.

State, local and foreign jurisdictions have differing rules and regulations governing sales, use, value added, and other taxes, and these rules and regulations are subject to varying interpretations that may change over time. In particular, the applicability of such taxes to our ecommerce platform in various jurisdictions is unclear. These jurisdictions’ rules regarding tax nexus are complex and vary significantly. As a result, we could face tax assessments and audits. Our liability for these taxes and associated penalties could exceed our original estimates. Jurisdictions in which we have not historically collected or accrued sales, use, value added, or other taxes could assert our liability for such taxes. This could result in substantial tax liabilities and related penalties for past sales. It could also discourage customers from using our platform or otherwise harm our business and operating results.

Changes in tax laws or regulations that are applied adversely to us or our customers could increase the cost of our ecommerce platform and adversely impact our business.

New income, sales, use, or other tax laws, statutes, rules, regulations, or ordinances could be enacted at any time. Any new taxes could adversely affect our domestic and international business operations and our business and financial performance. Existing tax laws, statutes, rules, regulations, or ordinances could be interpreted, changed, modified or applied adversely to us. These events could require us or customers using our ecommerce platform to pay additional tax amounts on a prospective or retroactive basis. They could require us or our customers to pay fines and/or penalties and interest for past amounts deemed to be due. If we raise our prices to offset the costs of these changes, existing and potential future customers may elect not to continue to subscribe or elect to subscribe to our ecommerce platform in the future. Additionally, new, changed, modified, or newly interpreted or applied tax laws could increase our customers’ and our compliance, operating and other costs, as well as the costs of our platform. Any or all of these events could adversely impact our business and financial performance.

Our current operations are international in scope, and we plan further geographic expansion. This will create a variety of operational challenges.

A component of our growth strategy involves the further expansion of our operations and customer base internationally. In the years ended December 31, 2018 and 2019, revenue generated from customers outside the United States was 18.3% and 18.8% of our total revenue, respectively. We currently have locations in the United States, Australia, the United Kingdom (“UK”), Singapore, and Ukraine. We are continuing to adapt and develop

41

strategies to address international markets, but such efforts may not be successful. In addition, the COVID-19 pandemic and related stay-at-home, business closure, and other restrictive orders and travel restrictions, may pose additional challenges for international expansion and may impact our ability to launch new locations and further expand geographically.

As of December 31, 2019, 14.2% of our full-time employees were located outside of the United States. In addition, 43 private entrepreneurs provide services to us in Ukraine. We expect that our international activities will continue to grow over the foreseeable future as we continue to pursue opportunities in existing and new international markets. This will require significant management attention and financial resources. We may face difficulties, including: (1) costs associated with developing software and providing support in many languages, (2) varying seasonality patterns, (3) potential adverse movement of currency exchange rates, (4) longer payment cycles and difficulties in collecting accounts receivable, (5) tariffs and trade barriers, (6) a variety of regulatory or contractual limitations on our ability to operate, (7) adverse tax events, (8) reduced protection of intellectual property rights, (9) a geographically and culturally diverse workforce and customer base, and (10) travel restrictions associated with the COVID-19 pandemic. Failure to overcome any of these difficulties could negatively affect our results of operations.

Our current international operations and future initiatives involve a variety of risks, including:

42

Our limited experience in operating our business internationally increases the risk that future expansion efforts that we may undertake will not be successful. If we invest substantial time and resources to expand our international operations and are unable to do so successfully, our business and operating results will suffer.

Our international operations may subject us to potential adverse tax consequences.

We are expanding our international operations and staff to better support our growth into international markets. Our corporate structure and associated transfer pricing policies contemplate future growth into the international markets, and consider the functions, risks, and assets of the various entities involved in the intercompany transactions. The amount of taxes we pay in different jurisdictions may depend: on (1) the application of the tax laws of the various jurisdictions, including the United States, to our international business activities, (2) changes in tax rates, (3) new or revised tax laws or interpretations of existing tax laws and policies, and (4) our ability to operate our business in a manner consistent with our corporate structure and intercompany arrangements. Taxing authorities may challenge the pricing methodologies of our intercompany arrangements or disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a challenge or disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest, and penalties. This could result in one-time tax charges, higher effective tax rates, reduced cash flows, and lower overall profitability of our operations. Our financial statements could fail to reflect adequate reserves to cover such a contingency.

The TCJA was enacted on December 22, 2017 and significantly reformed the Code. The TCJA, among other things: (1) includes changes to U.S. federal tax rates, (2) imposes additional limitations on the deductibility of interest, (3) has both positive and negative changes to the utilization of future NOL carryforwards as described above, (4) allows for the expensing of certain capital expenditures, and (5) puts into effect the migration from a “worldwide” system of taxation to a partially territorial system. Our net deferred tax assets and liabilities and valuation allowance was revalued at the newly enacted U.S. corporate rate. We continue to await guidance from the tax authorities on some of the changes that will affect us. Such future guidance could result in significant one-time charges in the current or future taxable years and could increase our future U.S. tax expense. The impact of this tax reform on holders of our Series 1 common stock is uncertain and could be adverse.

Loss of certain tax benefits that we enjoy in Ukraine could have a negative impact on our operating results and profitability.

Substantially all of the persons who provide services used by us in Ukraine are independent contractors who are registered as private entrepreneurs with the tax authorities. They are third-party suppliers operating as independent contractors, for whom we are not required to pay social duties and personal income tax applicable to employees. Nevertheless, Ukrainian tax authorities may take a view that would result in additional financial obligations. Ukrainian tax authorities could assert a position on the classification of our independent contractors contrary to ours. They could claim we had to withhold personal income tax and to accrue single social contribution in relation to employees’ remuneration. If a national authority or court enacts legislation or adopts regulations that change the manner in which employees and independent contractors are classified, or makes any

43

adverse determination with respect to some or all of our independent contractors, we could incur significant costs arising from fines or judgments as a result of tax withholding. All of these factors could in turn result in material adverse effects on our financial condition.

We are subject to governmental export and import controls that could impair our ability to compete in international markets and subject us to liability if we violate the controls.

Our platform is subject to U.S. export controls, including the Export Administration Regulations and economic sanctions administered by the U.S. Treasury Department’s Office of Foreign Assets Control. We incorporate encryption technology into our platform. These encryption products and the underlying technology may be exported outside of the United States only with the required export authorizations, including by license, a license exception or other appropriate government authorizations.

Furthermore, our activities are subject to the U.S. economic sanctions laws and regulations that prohibit the shipment of certain products and services to countries, governments, and persons targeted by U.S. embargoes or sanctions. The current administration has been critical of existing trade agreements and may impose more stringent export and import controls. Obtaining the necessary export license or other authorization for a particular sale may be time-consuming and may result in the delay or loss of sales opportunities even if the export license ultimately may be granted. While we take precautions to prevent our platform from being exported in violation of these laws, including obtaining authorizations for our platform, performing geolocation IP blocking and screenings against U.S. and other lists of restricted and prohibited persons, we cannot guarantee that the precautions we take will prevent violations of export control and sanctions laws. Violations of U.S. sanctions or export control laws can result in significant fines or penalties and possible incarceration for responsible employees and managers could be imposed for criminal violations of these laws.

If our partners fail to obtain appropriate import, export or re-export licenses or permits, we may also be adversely affected, through reputational harm as well as other negative consequences, including government investigations and penalties. We presently incorporate export control compliance requirements into our strategic partner agreements; however, no assurance can be given that our partners will comply with such requirements.

Various countries regulate the import and export of certain encryption and other technology, including import and export licensing requirements. Some countries have enacted laws that could limit our ability to distribute our platform or could limit our customers’ ability to implement our platform in those countries. Changes in our platform or future changes in export and import regulations may create delays in the introduction of our platform in international markets, prevent our customers with international operations from launching our platform globally or, in some cases, prevent the export or import of our platform to certain countries, governments, or persons altogether. Various governmental agencies have proposed additional regulation of encryption technology, including the escrow and government recovery of private encryption keys. Any change in export or import regulations, economic sanctions, or related legislation, or change in the countries, governments, persons, or technologies targeted by such regulations, could limit our ability to export or sell our platform to existing or potential customers with international operations. Any decreased use of our platform or limitation on our ability to export or sell our platform would adversely affect our business, operating results, and prospects.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our operating results.

Our customer subscription and partner and services contracts are primarily denominated in U.S. dollars, and therefore substantially all of our revenue is not subject to foreign currency risk. However, a strengthening of the U.S. dollar could increase the real cost of our platform to our customers outside of the United States, which could adversely affect our operating results. In addition, an increasing portion of our operating expenses is incurred and an increasing portion of our assets is held outside the United States. These operating expenses and assets are denominated in foreign currencies and are subject to fluctuations due to changes in foreign currency exchange

44

rates. If we are not able to successfully hedge against the risks associated with currency fluctuations, our operating results could be adversely affected.

We are subject to anti-corruption, anti-bribery, anti-money laundering, and similar laws. Non-compliance with such laws can subject us to criminal and/or civil liability and harm our business.

We are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the UK Bribery Act of 2010, the UK Proceeds of Crime Act 2002, and other anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption and anti-bribery laws have been enforced aggressively in recent years. These laws are interpreted broadly to prohibit companies and their employees and third-party intermediaries from authorizing, promising, offering, or providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. As we increase our international sales and business and sales to the public sector, we may engage with partners and third-party intermediaries to market our services and to obtain necessary permits, licenses, and other regulatory approvals. In addition, we or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners, and agents, even if we do not explicitly authorize such activities.

While we have policies and procedures to address compliance with such laws, our employees and agents could violate our policies and applicable law, for which we may be ultimately held responsible. As we increase our international sales and business, our risks under these laws may increase.

Noncompliance with anti-corruption, anti-bribery, or anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage, and other collateral consequences. If any subpoenas or investigations are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations, and financial condition could be materially harmed. Responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense costs and other professional fees. Enforcement actions and sanctions could further harm our business, results of operations, and financial condition.

Changes in subjective assumptions, estimates and judgments by management related to complex accounting matters or changes in accounting principles generally accepted in the United States, could significantly affect our financial condition and results of operations.

GAAP and related pronouncements, implementation guidelines, and interpretations apply to a wide range of matters that are relevant to our business, including revenue recognition, stock-based compensation, and deferred commissions. These matters are complex and involve subjective assumptions, estimates, and judgments by our management. Changes in GAAP, these accounting pronouncements or their interpretation or changes in underlying assumptions, estimates, or judgments by our management, the Financial Accounting Standards Board (“FASB”), the Securities and Exchange Commission (the “SEC”), and others could significantly change our reported or expected financial performance, which could impact the market price for our Series 1 common stock.

The terms of the agreements governing our indebtedness restrict, and any future indebtedness would likely restrict, our operations.

Our Second Amended and Restated Loan and Security Agreement (our “Credit Facility”), which we amended and restated in February 2020 (our “A&R Credit Facility”), 2017 Convertible Term Loan, and 2020 Convertible Term Loan, each with Silicon Valley Bank (“SVB”), and our Mezzanine Facility with

45

WestRiver Innovation Lending Fund VIII, L.P., contain, and any future indebtedness would likely contain, a number of covenants that impose significant operating and financial restrictions on us, including restrictions on our ability to take actions that may be in our best interests. Our A&R Credit Facility requires us to satisfy specified financial covenants. Our ability to meet those financial covenants can be affected by events beyond our control, and we may not be able to continue to meet those covenants. A breach of any of these covenants or the occurrence of other events specified in the A&R Credit Facility, 2017 Convertible Term Loan, 2020 Convertible Term Loan, and Mezzanine Facility could result in an event of default under the A&R Credit Facility, 2017 Convertible Term Loan, 2020 Convertible Term Loan, and Mezzanine Facility, as applicable. Upon the occurrence of an event of default, SVB could elect to declare all amounts outstanding under the A&R Credit Facility, 2017 Convertible Term Loan, 2020 Convertible Term Loan, and Mezzanine Facility to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay those amounts, SVB could proceed against the collateral granted to them to secure such indebtedness. We have pledged substantially all of our assets, including our intellectual property, as collateral under the A&R Credit Facility, 2017 Convertible Term Loan, 2020 Convertible Term Loan, and Mezzanine Facility.

If SVB accelerates the repayment of borrowings, if any, we may not have sufficient funds to repay our existing debt. Our outstanding balance for the A&R Credit Facility, 2017 Convertible Term Loan, and 2020 Convertible Term Loan were $22.8 million, $19.0 million, and $35.0 million, respectively, as of March 31, 2020. We had no balance outstanding for the Mezzanine Loan as of March 31, 2020. The revolving line of credit under our A&R Credit Facility is due to mature in October 2021, and the term loan under our A&R Credit Facility is due to mature in September 2021. The 2017 Convertible Term Loan maturity date is in October 2022, the 2020 Convertible Term Loan maturity date is February 28, 2025, and the Mezzanine Facility maturity date is March 1, 2023. We may seek to enter into an extension of such debt arrangements or enter into a new facility with another lender. We may not be able to extend the term or obtain other debt financing on terms that are favorable to us, if at all. If we are unable to obtain adequate financing or financing on satisfactory terms when required, our ability to support our business growth and to respond to business challenges could be significantly impaired, and our business may be harmed.

We may acquire or invest in companies, which may divert our management’s attention and result in additional dilution to our stockholders. We may be unable to integrate acquired businesses and technologies successfully or achieve the expected benefits of such acquisitions.

We may evaluate and consider potential strategic transactions, including acquisitions of, or investments in, businesses, technologies, services, products, and other assets in the future. An acquisition, investment or business relationship may result in unforeseen operating difficulties and expenditures. In particular, we may encounter difficulties assimilating or integrating the businesses, technologies, products, personnel, or operations of the acquired companies. Key personnel of the acquired companies may choose not to work for us, their software may not be easily adapted to work with ours, or we may have difficulty retaining the customers of any acquired business due to changes in ownership, management, or otherwise. We may also experience difficulties integrating personnel of the acquired company into our business and culture. Acquisitions may also disrupt our business, divert our resources and require significant management attention that would otherwise be available for development of our existing business. The anticipated benefits of any acquisition, investment, or business relationship may not be realized or we may be exposed to unknown risks or liabilities.

Negotiating these transactions can be time-consuming, difficult, and expensive, and our ability to close these transactions may often be subject to approvals that are beyond our control. Consequently, these transactions, even if undertaken and announced, may not close. For one or more of those transactions, we may:

Risks related to owning our Series 1 common stock and this offering

There may not be an active trading market for our Series 1 common stock, which may cause shares of our Series 1 common stock to trade at a discount from the initial public offering price and make it difficult to sell the shares of Series 1 common stock you purchase.

Prior to this offering, there has been no public market for our Series 1 common stock. It is possible that after this offering, an active trading market will not develop or, if developed, that any market will not be sustained. This would make it difficult for you to sell your shares of Series 1 common stock at an attractive price or at all. The initial public offering price per share of Series 1 common stock was determined through discussions among the representatives of the underwriters and us. It may not be indicative of the price at which shares of our Series 1 common stock will trade in the public market after this offering.

The market price of shares of our Series 1 common stock may be volatile, which could cause the value of your investment to decline.

Even if an active trading market develops, the market price of our Series 1 common stock may be highly volatile and could be subject to wide fluctuations. Securities markets worldwide experience significant price and volume fluctuations. The securities markets have experienced significant volatility as a result of the COVID-19 pandemic. Market volatility, as well as general economic, market, or political conditions, could reduce the market price of shares of our Series 1 common stock regardless of our operating performance.

Our operating results could be below the expectations of public market analysts and investors due to a number of potential factors, including: (1) variations in our quarterly operating results or dividends, if any, to stockholders, (2) additions or departures of key management personnel, (3) publication of research reports about our industry, (4) litigation and government investigations, (5) changes or proposed changes in laws or regulations or differing interpretations or enforcement of laws or regulations affecting our business, (6) adverse market reaction to any indebtedness we may incur or securities we may issue in the future, (7) changes in market valuations of similar companies, (8) speculation in the press or investment community, (9) announcements by our competitors of significant contracts, acquisitions, dispositions, strategic partnerships, joint ventures, or capital commitments, (10) the impact of the COVID-19 pandemic on our management, employees, partners, customers, and operating results, and (11) adverse publicity about the industries we participate in or individual scandals. In response, the market price of shares of our Series 1 common stock could decrease significantly. You may be unable to resell your shares of Series 1 common stock at or above the initial public offering price.

Following periods of volatility in the overall market and the market price of a company’s securities, securities class action litigation has often been instituted against these companies. Such litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

Our ability to timely raise capital in the future may be limited, or may be unavailable on acceptable terms, if at all. Our failure to raise capital when needed could harm our business, operating results and financial condition. Debt or equity issued to raise additional capital may reduce the value of our Series 1 common stock.

We have funded our operations since inception primarily through equity financings, debt, and payments by our customers for use of our platform and related services. We cannot be certain when or if our operations will generate sufficient cash to fund our ongoing operations or the growth of our business.

47

We intend to continue to make investments to support our business and may require additional funds. Additional financing may not be available on favorable terms, if at all. If adequate funds are not available on acceptable terms, we may be unable to invest in future growth opportunities, which could harm our business, operating results and financial condition. If we incur additional debt, the debt holders could have rights senior to holders of Series 1 common stock to make claims on our assets. The terms of any debt could restrict our operations, including our ability to pay dividends on our Series 1 common stock. If we issue additional equity securities, stockholders will experience dilution, and the new equity securities could have rights senior to those of our Series 1 common stock. Because our decision to issue securities in the future offering will depend on numerous considerations, including factors beyond our control, we cannot predict or estimate the amount, timing or nature of any future issuances of debt or equity securities. As a result, our stockholders bear the risk of future issuances of debt or equity securities reducing the value of our Series 1 common stock and diluting their interest.

Insiders will continue to have substantial control over us after this offering, which may limit our stockholders’ ability to influence corporate matters and delay or prevent a third party from acquiring control over us.

Upon completion of this offering (assuming no exercise of the underwriters’ option to purchase additional shares from us or the selling stockholders), our directors, executive officers, and current beneficial owners of 5% or more of our voting securities and their respective affiliates will beneficially own, in the aggregate, approximately 67% of our outstanding Series 1 common stock compared to approximately 15% represented by the shares sold in this offering excluding any potential purchases in this offering by the foregoing persons and entities. Further, we anticipate that Steven Murray, a member of our board of directors and the operating manager of the ultimate general partner of Revolution Growth, Lawrence Bohn, a member of our board of directors and a partner of General Catalyst Group, and Jeff Richards, a member of our board of directors and managing director of GGV Capital, will beneficially own an aggregate of approximately 14%, 15%, and 5% of our Series 1 common stock, respectively, following this offering excluding any potential purchases in this offering by the foregoing persons and entities. This significant concentration of ownership may adversely affect the trading price for our Series 1 common stock because investors often perceive disadvantages in owning stock in companies with controlling stockholders. In addition, these stockholders will be able to exercise influence over all matters requiring stockholder approval, including the election of directors and approval of corporate transactions, such as a merger or other sale of our company or its assets. This concentration of ownership could limit your ability to influence corporate matters and may have the effect of delaying or preventing a change in control, including a merger, consolidation or other business combination involving us, or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control, even if that change in control would benefit our other stockholders. For information regarding the ownership of our outstanding stock by our executive officers, directors, and current beneficial owners of 5% or more of our voting securities and their respective affiliates, please see the section titled “Principal and Selling Stockholders.”

We have no current plans to pay cash dividends on our Series 1 common stock; as a result, you may not receive any return on investment unless you sell your Series 1 common stock for a price greater than that which you paid for it.

We have no current plans to pay dividends on our Series 1 common stock. Any future determination to pay dividends will be made at the discretion of our board of directors, subject to applicable laws. It will depend on a number of factors, including our financial condition, results of operations, capital requirements, contractual, legal, tax and regulatory restrictions, general business conditions, and other factors that our board of directors may deem relevant. In addition, our ability to pay cash dividends is restricted by the terms of our debt financing arrangements, and any future debt financing arrangement likely will contain terms restricting or limiting the amount of dividends that may be declared or paid on our common stock. As a result, you may not receive any return on an investment in our Series 1 common stock unless you sell your Series 1 common stock for a price greater than that which you paid for it.

48

If our operating and financial performance in any given period does not meet the guidance that we provide to the public or the expectations of investment analysts, the market price of our Series 1 common stock may decline.

We may, but are not obligated to, provide public guidance on our expected operating and financial results for future periods. Any such guidance will comprise forward-looking statements, subject to the risks and uncertainties described in this prospectus and in our other public filings and public statements. Our ability to provide this public guidance, and our ability to accurately forecast our results of operations, may be impacted by the COVID-19 pandemic. Our actual results may not always be in line with or exceed any guidance we have provided, especially in times of economic uncertainty, such as the current global economic uncertainty being experienced as a result of the COVID-19 pandemic. If, in the future, our operating or financial results for a particular period do not meet any guidance we provide or the expectations of investment analysts, or if we reduce our guidance for future periods, the market price of our Series 1 common stock may decline as well. Even if we do issue public guidance, there can be no assurance that we will continue to do so in the future.

We will incur increased costs and become subject to additional regulations and requirements as a result of becoming a public company. This could lower our profits or make it more difficult to run our business.

As a public company, we will incur significant legal, accounting, and other expenses that we have not incurred as a private company, including costs associated with public company reporting requirements. We also have incurred and will continue to incur costs associated with the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”), and related rules implemented by the SEC and Nasdaq. The expenses generally incurred by public companies for reporting and corporate governance purposes have been increasing. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. We are currently unable to estimate these costs with any certainty. These laws and regulations also could make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance. We may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, on our board committees, or as our executive officers. If we are unable to satisfy our obligations as a public company, we could be subject to delisting of our Series 1 common stock, fines, sanctions, and other regulatory action and potentially civil litigation.

We are an “emerging growth company.” The reduced public company reporting requirements applicable to emerging growth companies may make our Series 1 common stock less attractive to investors.

We qualify as an “emerging growth company,” as defined in the JOBS Act. While we remain an emerging growth company, we are permitted and plan to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These provisions include: (1) presenting only two years of audited financial statements, (2) presenting only two years of related selected financial data and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure, (3) an exemption from compliance with the auditor attestation requirement in the assessment of our internal control over financial reporting pursuant to Section 404 of Sarbanes-Oxley, (4) not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, (5) reduced disclosure obligations regarding executive compensation arrangements in our periodic reports, registration statements, and proxy statements, and (6) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, the information we provide will be different than the information that is available with respect to other public companies that are not emerging growth companies.

49

In this prospectus, we have not included all of the executive compensation-related information that would be required if we were not an emerging growth company. We cannot predict whether investors will find our Series 1 common stock less attractive if we rely on these exemptions. If some investors find our Series 1 common stock less attractive as a result, there may be a less active trading market for our Series 1 common stock. The market price of our Series 1 common stock may be more volatile.

We will remain an emerging growth company until the earliest of: (1) the end of the fiscal year in which the fifth anniversary of the closing of this offering occurs, (2) the first fiscal year after our annual gross revenue exceed $1.07 billion, (3) the date on which we have, during the immediately preceding three-year period, issued more than $1.0 billion in non-convertible debt securities, and (4) the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeds $700 million as of the end of the second quarter of that fiscal year.

If we are unable to implement and maintain effective internal control over financial reporting in the future, investors may lose confidence in the accuracy and completeness of our financial reports, and the market price of our Series 1 common stock may decline.

As a public company, we will be required to maintain internal controls over financial reporting and to report any material weaknesses in such internal controls. In addition, beginning with our second annual report on Form 10-K, we will be required to furnish a report by management on the effectiveness of our internal control over financial reporting, pursuant to Section 404 of Sarbanes-Oxley. The process of designing, implementing, and testing the internal control over financial reporting required to comply with this obligation is time-consuming, costly, and complicated.

If we identify material weaknesses in our internal control over financial reporting, if we are unable to comply with the requirements of Section 404 of Sarbanes-Oxley in a timely manner, or if we are unable to assert that our internal control over financial reporting is effective, we will be unable to certify that our internal control over financial reporting is effective. We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition or results of operations. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness or significant deficiency in our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our Series 1 common stock could decline. We could become subject to investigations by the stock exchange on which our securities are listed, the SEC or other regulatory authorities, which could require additional financial and management resources.

Increases in interest rates may cause the market price of our Series 1 common stock to decline.

Interest rates are at or near record lows. Increases in interest rates may cause a corresponding decline in demand for equity investments. Any such increase in interest rates or reduction in demand for our Series 1 common stock resulting from other relatively more attractive investment opportunities may cause the market price of our Series 1 common stock to decline.

If securities or industry analysts do not publish research or reports about our business or publish negative reports, the market price of our Series 1 common stock could decline.

The trading market for our Series 1 common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If regular publication of research reports ceases, we could lose visibility in the financial markets, which in turn could cause the market price or trading volume of our Series 1 common stock to decline. Moreover, if one or more of the analysts who cover us downgrades our Series 1 common stock or if our reporting results do not meet their expectations, the market price of our Series 1 common stock could decline.

50

We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

Our management currently intends to use the net proceeds from this offering in the manner described in “Use of Proceeds” and will have broad discretion in the application of a significant part of the net proceeds from this offering. The failure by our management to apply these funds effectively could result in financial losses that could harm our business, cause the market price of our Series 1 common stock to decline, and delay the development of our operations. We may invest the net proceeds from this offering in a manner that does not contribute to the growth and financial performance of our business, which would negatively impact the value of our Series 1 common stock.

Investors in this offering will experience immediate and substantial dilution.

The initial public offering price per share of Series 1 common stock will be substantially higher than our pro forma net tangible book value per share immediately after this offering. If you purchase shares of our Series 1 common stock in this offering, you will suffer immediate dilution of $21.74 per share, or $21.43 per share if the underwriters exercise their option to purchase additional shares in full. This represents the difference between (1) our pro forma as adjusted net tangible book value per share after giving effect to the sale of Series 1 common stock in this offering, and (2) the initial public offering price of $24.00 per share. See “Dilution.”

You will be diluted by the future issuance of common stock, preferred stock or securities convertible into common or preferred stock, in connection with our incentive plans, acquisitions, capital raises or otherwise.

After this offering we will have outstanding 60,792,991 shares of Series 1 common stock and 5,050,555 shares of Series 2 common stock. Our amended and restated certificate of incorporation, which will become effective prior to the closing of this offering, authorizes us to issue these shares of common stock and options, rights, warrants, and appreciation rights relating to common stock for the consideration and on the terms and conditions established by our board of directors in its sole discretion, whether in connection with acquisitions or otherwise.

In the future, we expect to obtain financing or to further increase our capital resources by issuing additional shares of our capital stock or offering debt or other equity securities, including senior or subordinated notes, or debt securities convertible into equity or shares of preferred stock. Issuing additional shares of our capital stock or other equity securities or securities convertible into equity may dilute the economic and voting rights of our existing stockholders or reduce the market price of our Series 1 common stock or both. Debt securities convertible into equity could be subject to adjustments in the conversion ratio pursuant to which certain events may increase the number of equity securities issuable upon conversion. Shares of preferred stock, if issued, could have a preference with respect to liquidating distributions or a preference with respect to dividend payments that could limit our ability to pay dividends to the holders of our Series 1 common stock. Additional shares of Series 2 common stock, if issued, may further dilute the economic rights of our Series 1 common stock. Holders of our Series 1 common stock are not entitled to receive economic consideration per share for their shares in excess of that payable to the holders of the then outstanding shares of Series 2 common stock in the event of a merger, consolidation or tender or exchange offer. Our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, which may adversely affect the amount, timing, or nature of our future offerings. As a result, holders of our Series 1 common stock bear the risk that our future offerings may reduce the market price of our Series 1 common stock and dilute their stockholdings in us. See “Description of Capital Stock.”

We have initially reserved 3,873,885 shares of Series 1 common stock for issuance under our 2020 Plan, which may be increased by shares that remained available for issuance under our 2013 Plan upon its termination or that are subject to awards granted under our 2013 Plan that may expire or terminate without having been exercised or settled in full. Any Series 1 common stock that we issue, including under our 2013 Plan and 2020

51

Plan or other equity incentive plans that we may adopt in the future, would dilute the percentage ownership held by the investors who purchase Series 1 common stock in this offering. We intend to file one or more registration statements on Form S-8 under the Securities Act of 1933, as amended (the “Securities Act”), to register shares of our Series 1 common stock or securities convertible into or exchangeable for shares of our Series 1 common stock issued pursuant to our 2013 Plan, 2020 Plan, and 2020 ESPP. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market.

If we or the pre-IPO investors sell additional shares of our Series 1 common stock after this offering, the market price of our Series 1 common stock could decline.

The sale of substantial amounts of shares of our Series 1 common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our Series 1 common stock. These sales, or the possibility that these sales may occur, might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. Upon the closing of this offering, we will have a total of 60,792,991 shares of our Series 1 common stock outstanding (or 61,820,491 shares if the underwriters exercise in full their option to purchase additional shares of Series 1 common stock) and an additional 411,268 shares of our Series 1 common stock issuable upon the full exercise of our outstanding warrants. Of the outstanding 60,792,991 shares of Series 1 common stock, the 9,019,565 shares sold in this offering (or 10,372,500 shares if the underwriters exercise in full their option to purchase additional shares of Series 1 common stock) will be freely tradable without restriction or further registration under the Securities Act, except that any shares held by our affiliates, as that term is defined under Rule 144 of the Securities Act, may be sold only in compliance with the limitations described in “Shares Eligible for Future Sale.”

The remaining 51,773,426 outstanding shares of Series 1 common stock held by or issuable to our pre-IPO investors and management after this offering will be subject to certain restrictions on resale. We, our officers, directors, and certain pre-IPO investors that collectively will own substantially all of such shares of Series 1 common stock (including shares issuable on exchange of Series 2 common stock) following this offering have signed lock-up agreements with the underwriters or are subject to comparable lock-up restrictions. Subject to certain customary exceptions, these agreements restrict the sale of the shares of our Series 1 common stock held for 180 days following the date of this prospectus. Morgan Stanley & Co. LLC and Barclays Capital Inc., in their sole discretion, may release the securities subject to these lock-up agreements described above in whole or in part at any time prior to the expiration of the restrictive provisions contained in those lock-up agreements. Upon the expiration of the lock-up agreements, all of such shares of Series 1 common stock will be eligible for resale in a public market, subject, in the case of shares held by our affiliates, to volume, manner of sale, and other limitations under Rule 144. Commencing 180 days following this offering, certain pre-IPO investors will have the right, subject to certain exceptions and conditions, to require us to register their shares of Series 1 common stock under the Securities Act, and they will have the right to participate in future registrations of securities by us. Registration of any of these outstanding shares of Series 1 common stock would result in such shares becoming freely tradable without compliance with Rule 144 upon effectiveness of the registration statement. See “Shares Eligible for Future Sale.”

As restrictions on resale end, the market price of our shares of Series 1 common stock could drop significantly if the holders of these restricted shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our shares of common stock or other securities.

Provisions in our organizational documents and certain rules imposed by regulatory authorities may delay or prevent our acquisition by a third party.

Our amended and restated certificate of incorporation and amended and restated bylaws will contain several provisions that may make it more difficult or expensive for a third party to acquire control of us without the

52

approval of our board of directors. These provisions, which may delay, prevent or deter a merger, acquisition, tender offer, proxy contest, or other transaction that stockholders may consider favorable, include the following:

These provisions of our amended and restated certificate of incorporation and amended and restated bylaws could discourage potential takeover attempts and reduce the price that investors might be willing to pay for shares of our Series 1 common stock in the future, which could reduce the market price of our Series 1 common stock. For more information, see “Description of Capital Stock.”

The provision of our amended and restated certificate of incorporation requiring exclusive venue in the Court of Chancery in the State of Delaware and the federal district courts of the United States for certain types of lawsuits may have the effect of discouraging lawsuits against our directors and officers.

Our amended and restated certificate of incorporation will provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware be the sole and exclusive forum for: (1) any derivative action or proceeding brought on behalf of our company, (2) any action asserting a claim of breach of fiduciary duty owed by any director (including any director serving as a member of the Executive Committee), officer, agent or other employee or stockholder of our company to us or our stockholders, (3) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law (“DGCL”), the amended and restated certificate of incorporation or our bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (4) any action asserting a claim governed by the internal affairs doctrine, in each case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. It will further provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolutions of any complaint asserting a cause of action arising under the Securities Act. The exclusive forum clauses described above shall not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any other claim for which the federal courts have exclusive jurisdiction.

Although we believe these provisions benefit us by providing increased consistency in the application of applicable law in the types of lawsuits to which they apply, the provisions may have the effect of discouraging lawsuits against our directors and officers. The enforceability of similar choice of forum provisions in other

53

companies’ certificates of incorporation has been challenged in legal proceedings and there is uncertainty as to whether a court would enforce such provisions. In addition, investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. It is possible that, in connection with any applicable action brought against us, a court could find the choice of forum provisions contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in such action. If so, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

Special Note Regarding Forward-Looking Statements

This prospectus contains forward-looking statements. Any statements about our expectations, beliefs, plans, predictions, forecasts, objectives, assumptions, or future events or performance are not historical facts and may be forward-looking. These statements are often, but not always, made through the use of words or phrases such as “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will,” and similar words or phrases. These forward-looking statements include statements concerning the following:

Although we believe the expectations reflected in these forward-looking statements are reasonable, these statements are not guarantees of future performance and involve risks and uncertainties which are subject to change based on various important factors, some of which are beyond our control. For more information regarding these risks and uncertainties as well as certain additional risks that we face, refer to “Risk Factors,” as well as factors more fully described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this prospectus.

If one or more of the factors affecting the expectations reflected in our forward-looking information and statements proves incorrect, our actual results, performance, or achievements could differ materially from those expressed in, or implied by, forward-looking information and statements. Therefore, we caution the reader not to place undue reliance on any forward-looking information or statements. The effect of these factors is difficult to predict. Factors other than these also could adversely affect our results, and the reader should not consider these factors to be a complete set of all potential risks or uncertainties. New factors emerge from time to time, and management cannot assess the impact of any such factor on our business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. Any forward-looking statements only speak as of the date of this document, and we undertake no obligation to update any forward-looking information or statements, whether written or oral, to reflect any change, except as required by law. All forward-looking statements attributable to us are expressly qualified by these cautionary statements.

Market, Industry, and Other Data

This prospectus includes estimates regarding market and industry data and forecasts, which are based on publicly available information, industry publications, and surveys, including from eMarketer, Forrester, Gartner, IDC, and Vertical Web Media LLC (publisher of Digital Commerce 360 and Internet Retailer). These estimates are also based on reports from government agencies and our own estimates based on our management’s knowledge of, and experience in, the industry and markets in which we compete. We have not independently verified the accuracy or completeness of the data contained in third-party publications and reports and other publicly available information referred to in this prospectus. None of the third-party publications or reports referred to in this prospectus were prepared on our or on our affiliates’ behalf or at our expense.

The sources of certain statistical data, estimates, and forecasts contained in this prospectus are the following independent industry publications or reports:

The Forrester studies described herein represent data, research, opinions, or viewpoints prepared by Forrester and are not representations of fact. We have been advised by Forrester that its studies speak as of their original date (and not as of the date of this prospectus) and any opinions expressed in the studies are subject to change without notice.

The Gartner reports described herein represent research opinion or viewpoints published, as part of a syndicated subscription service by Gartner, and are not representations of fact. Each Gartner report speaks as of its original publication date (and not as of the date of this prospectus), and the opinions expressed in the Gartner reports are subject to change without notice. Gartner Peer Insights Customers’ Choice constitute the subjective opinions of individual end-user reviews, ratings, and data applied against a documented methodology; they neither represent the views of, nor constitute an endorsement by, Gartner or its affiliates.

Certain of the market research included in this prospectus was published prior to the outbreak of the pandemic and did not anticipate the virus or the impact it has caused on the adoption of ecommerce. We have utilized this pre-pandemic market research in the absence of updated sources. Similarly, our commentary on industry trends and the market opportunity primarily reflects beliefs held before the pandemic occurred. We are still learning from and reacting to this rapidly evolving situation.

56

In presenting this information, we have made certain assumptions that we believe to be reasonable based on such data and other similar sources, and on our knowledge of, and our experience to date in, the markets for our products. Market data is subject to change and may be limited by the availability of raw data, the voluntary nature of the data gathering process, and other limitations inherent in any statistical survey of market data. These data involve a number of assumptions and limitations which are necessarily subject to a high degree of uncertainty. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in “Risk Factors,” that could cause our future performance to differ materially from our assumptions and estimates. In addition, customer preferences are subject to change. Accordingly, you are cautioned not to place undue reliance on such market data.

57

Use of Proceeds

We estimate that our net proceeds from the sale of our Series 1 common stock in this offering will be approximately $149.0 million (or approximately $172.0 million if the underwriters fully exercise their option to purchase additional shares from us in this offering), and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We will not receive any of the proceeds of the sale of shares of Series 1 common stock by the selling stockholders.

The principal purposes of this offering are to increase our financial flexibility, create a public market for our Series 1 common stock, and facilitate future access to the public equity markets. We intend to use a portion of the net proceeds from this offering to pay in cash the Series F Dividend, which is expected to total $14.6 million as of the closing of this offering. As a result of the anticipated payment of the Series F Dividend, holders of our Series F preferred stock are expected to receive approximately $14.6 million of the net proceeds of this offering, including entities affiliated with General Catalyst Group and Lawrence Bohn, a member of our board of directors, and entities affiliated with GGV Capital and Jeff Richards, a member of our board of directors, which are expected to receive approximately $0.1 million and $0.2 million, respectively. We intend to use the remainder of the net proceeds from this offering for working capital and general corporate purposes, including sales and marketing, research and development, general and administrative matters, and capital expenditures. We may also use a portion of the net proceeds from this offering to acquire, license, or invest in products, technologies or businesses that are complementary to our business. However, we currently have no agreements or commitments to complete any such transaction.

Our expected use of net proceeds from this offering represents our current intentions based upon our present plans and business condition. As of the date of this prospectus, we cannot predict with complete certainty all of the particular uses for the net proceeds to be received upon the closing of this offering or the actual amounts that we will spend on the uses set forth above.

The timing and amount of our actual application of the net proceeds from this offering will be based on many factors, including our cash flows from operations and the growth of our business. We may find it necessary or advisable to use the net proceeds for other purposes, and we will have broad discretion in the application of the net proceeds. Pending the uses described above, we plan to invest the net proceeds from this offering in short-term, interest-bearing obligations, investment-grade instruments, certificates of deposit, or direct or guaranteed obligations of the U.S. government.

58

Dividend Policy

We do not anticipate declaring or paying any cash dividends on our capital stock in the foreseeable future, other than the accrued and unpaid Series F Dividend of $14.6 million to be paid in cash immediately prior to the closing of this offering. Any future determination to declare and pay cash dividends, if any, will be made at the discretion of our board of directors and will depend on a variety of factors, including applicable laws, our financial condition, results of operations, contractual restrictions, capital requirements, business prospects, general business or financial market conditions, and other factors our board of directors may deem relevant. In addition, our ability to pay cash dividends is currently restricted by the terms of the agreements governing our A&R Credit Facility, our 2017 Convertible Term Loan, our 2020 Convertible Term Loan, and our Mezzanine Facility. Our ability to pay cash dividends on our capital stock in the future may also be limited by the terms of any preferred securities we may issue or agreements governing any additional indebtedness we may incur.

59

Capitalization

The following table sets forth our cash and cash equivalents and capitalization as of March 31, 2020 on:

60

You should read this table, together with the information contained in this prospectus, including “Use of Proceeds,” “Selected Consolidated Financial Data,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the audited consolidated financial statements and related notes included elsewhere in this prospectus.

The outstanding share information in the table above excludes:

Dilution

If you invest in the initial public offering of our Series 1 common stock, your interest will be diluted to the extent of the excess of the initial public offering price per share of our Series 1 common stock over the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering.

Our historical net tangible book value (deficit) as of March 31, 2020 was $(261.7) million, or $(13.78) per share of common stock. Our historical net tangible book value (deficit) is the amount of our total tangible assets less our total liabilities and the carrying value of our redeemable convertible preferred stock, which is not included within stockholders’ equity (deficit). Historical net tangible book value (deficit) per share represents historical net tangible book value (deficit) divided by the total number of shares of Series 1 common stock and Series 2 common stock outstanding as of March 31, 2020.

Our pro forma net tangible book value as of March 31, 2020 was $(0.9) million, or $(0.02) per share of common stock. Pro forma net tangible book value represents the amount of our total tangible assets less our total liabilities, after giving effect to: (i) the automatic conversion of all outstanding shares of our preferred stock (excluding the shares of Series F preferred stock issuable upon conversion of the 2017 Convertible Term Loan and the exercise of the Purchase Right) into an aggregate of 29,390,733 shares of Series 1 common stock and 5,050,555 shares of Series 2 common stock, (ii) the conversion of our 2017 Convertible Term Loan into shares of our Series F preferred stock, at a conversion price of $3.059 per share, and the automatic conversion of such shares into 2,056,772 shares of Series 1 common stock, (iii) the exercise of the Purchase Right at the option of the lenders under our 2017 Convertible Term Loan for the purchase of shares of our Series F preferred stock at a purchase price of $3.059, and the automatic conversion of such shares into 122,588 shares of Series 1 common stock, (iv) the conversion of our 2020 Convertible Term Loan into 3,070,174 shares of Series 1 common stock, at an as-adjusted conversion price of $11.40 per share, and (v) the payment in cash of the Series F Dividend, which is expected to total $14.6 million as of the closing of this offering, in each case immediately prior to the closing of this offering. Pro forma net tangible book value per share represents pro forma net tangible book value divided by the total number of shares of Series 1 common stock and Series 2 common stock outstanding as of March 31, 2020, after giving effect to the pro forma adjustments described above.

After giving effect to the sale and issuance by us of 6,850,000 shares of Series 1 common stock in this offering, at an initial public offering price of $24.00 per share of Series 1 common stock, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value at March 31, 2020 would have been $148.1 million, or $2.26 per share of common stock. Dilution per share to new investors purchasing shares in this offering is determined by subtracting pro forma as adjusted net tangible book value per share after this offering from the initial public offering price per share of Series 1 common stock paid by new investors purchasing shares in this offering.

The following table illustrates the immediate dilution on a per share basis to new investors purchasing shares in this offering.

63

If the underwriters exercise in full their option to purchase additional shares of Series 1 common stock from us or the selling stockholders in this offering, our pro forma as adjusted net tangible book value after the offering would be $2.57 per share, and the dilution to new investors would be $21.43 per share, in each case at an initial public offering price of $24.00 per share, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

The following table summarizes, on the same pro forma as adjusted basis described above as of March 31, 2020, the total number of shares of common stock purchased from us, the total cash consideration paid to us and the average price per share paid by existing stockholders and by new investors purchasing shares of Series 1 common stock in this offering at an initial stock price of $24.00 per share, before deducting underwriting discounts and commissions and estimated offering expenses payable by us.

Sales by the selling stockholders in this offering will cause the number of shares held by existing stockholders to be reduced to 56,823,981 shares, or 86.3% of the total number of shares of our capital stock outstanding following the completion of this offering, and will increase the number of shares held by new investors to 9,019,565 shares, or 13.7% of the total number of shares of our capital stock outstanding following the completion of this offering.

If the underwriters exercise in full their option to purchase additional shares of Series 1 common stock, the percentage of shares of our common stock held by existing stockholders would be decreased to 84.5% of the total number of our common stock outstanding after this offering, and the number of shares held by new investors participating in this offering would be increased to 15.5% of the total number of shares of our common stock outstanding after this offering.

The foregoing table excludes:

64

To the extent any of the outstanding options or warrants are exercised or new options or other securities are issued under our equity incentive plans, you will experience further dilution as a new investor in this offering. In addition, we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. If we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

65

Selected Consolidated Financial Data

The following tables present selected consolidated financial data for our business. The selected statement of operations data presented below for the years ended December 31, 2018 and 2019 and the selected balance sheet data as of December 31, 2018 and 2019 have been derived from our audited consolidated financial statements appearing at the end of this prospectus. The selected statement of operations data presented below for the three months ended March 31, 2019 and 2020 and the selected balance sheet data as of March 31, 2020 have been derived from our unaudited consolidated financial statements appearing at the end of this prospectus. In the opinion of management, the unaudited data reflects all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the financial information in those statements. Our historical results are not necessarily indicative of the results that should be expected in the future and the results for the three months ended March 31, 2020 are not necessarily indicative of the results to be expected for the full year ending December 31, 2020 or any other future period. The following selected historical consolidated financial data is qualified in its entirety by reference to, and should be read in conjunction with, our audited consolidated financial statements and related notes, and the information under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and other financial information included in this prospectus.
