The story

The company was founded in 2013 by Andrew Bialecki and Ed Hallen. Both Bialecki and Hallen had previously worked at Applied Predictive Technologies.

In August 2022, e-commerce company Shopify announced it was making Klaviyo the recommended email solution partner for its Shopify Plus merchant platform, with a US$100,000,000 strategic investment into the company.

In November 2022, Klaviyo announced its first acquisition, code development firm Napkin.io.

In April 2023, Klaviyo filed for an initial public offering (IPO) for a listing at the New York Stock Exchange. In September, the company went public, raising $576 million in the IPO at a $9.2 billion valuation.

In June 2023, Klaviyo partnered with e-commerce platform Prestashop with the launch of Prestashop Automation with Klaviyo

In 2023, Klaviyo first introduced AI-powered features, which as of 2025 include Marketing Agent, which automates campaign planning and optimization, and Customer Agent, which provides 24/7 customer service automation. The launches reflected the company's expansion from a marketing automation platform toward an AI-powered B2C CRM platform integrating customer data, automation, and omnichannel engagement.

In 2024, the Klaviyo Marketing Platform was localised into six non-English languages, French, German, Spanish, Italian, Korean and Brazilian Portuguese. In 2025 the platform was further localised into Dutch, Polish, Mexican Spanish and Swedish.

In August 2025, Klaviyo announced it had acquired Gatsby, a customer engagement platform. The acquisition expands the Klaviyo platform's capabilities to include social media marketing.

Risk factors and legal proceedings

The risks Klaviyo names in Item 1A of its 10-K filed Feb 10, 2026: 62 risks under these headings, as written.16

  • Risks Relating to Our Business and Industry
  • Our rapid historical revenue growth is not indicative of our future revenue growth, and we may not be able to sustain our historical revenue growth rate, in the near term and in the future.
  • Our business has experienced rapid growth, and if we fail to effectively manage our growth or anticipated growth, our business, results of operations, and financial condition could be adversely affected.
  • We have a limited operating history in a rapidly changing industry, which makes it difficult to evaluate our current business and future prospects and increases the risk of your investment.
  • We operate in a highly competitive industry, and if we do not compete effectively with established companies or new market entrants, our business, results of operations, and financial condition could be adversely affected.
  • Our business and success depend, in part, on our ability to successfully integrate with third-party platforms, especially with eCommerce platforms such as Shopify, and our business could be harmed as a result of any disruptions to these third-party platform integrations or our relationships with third-party platform providers.
  • Our business and success depend, in part, on the success of our relationships with third parties, such as our marketing agency and technology partners.
  • Unfavorable conditions in our industry or the global economy, or reductions in spending on marketing, could adversely affect our business, financial condition, and results of operations.
  • We may not be able to add new customers, retain existing customers, or increase sales to existing customers, which could adversely affect our business, results of operations, and financial condition.
  • We have a history of net losses, we anticipate increasing operating expenses in the future, and we may not be able to achieve and maintain profitability in the future.
  • As we seek to move up-market, we expect our sales cycle with enterprise customers to be longer than with small-and-mid size businesses and we will be required to scale our operations, including by expanding our sales efforts, which may require considerable time and expense.
  • We have historically invested significantly in research and development and expect this investment to continue. If these investments do not translate into new products or enhancements to our current products or product features, or if we do not use those investments efficiently, our business, financial condition, and results of operations could be adversely affected.
The other 51 risks
  • If we fail to adapt and respond effectively to technological changes, evolving industry standards, changing regulations or changing customer or consumer needs, requirements or preferences, our platform may become less competitive.
  • We depend on our senior management team, and the loss of one or more members of our senior management team or our key employees, or an inability to attract and retain highly skilled employees, could adversely affect our business.
  • If we fail to maintain and enhance our brand, our ability to maintain or expand our customer base may be impaired and our business, financial condition, and results of operations could be adversely affected.
  • Doing business internationally exposes us to significant risks, and our future success depends in part on our ability to navigate the international business environment and drive the adoption of our products by international customers.
  • Our business and reputation could be adversely affected if our customers are not satisfied with the integration or implementation of our platform and products provided by us or our partners.
  • We may continue to experience quarterly fluctuations in our results of operations due to a number of factors that make our future results difficult to predict, could cause the trading price of our Series A common stock to fluctuate, and could cause our results of operations to fall below analyst or investor expectations.
  • We rely upon a third-party provider of cloud-based infrastructure to host and sell our products. Any disruption in the operations of this provider or limitations on capacity or interference with our use could adversely affect our business, financial condition, and results of operations.
  • Our business depends on our ability to send consumer engagement messages, including emails, text messages and WhatsApp messages, and any significant disruption in service with our third-party providers or on mobile operating systems could result in a loss of customers or less effective consumer-brand engagement, which could harm our business, financial condition, and results of operations.
  • We rely heavily on the reliability, security, and performance of our software. If our software contains serious errors or defects, or we have difficulty maintaining our software, we may lose revenue and market acceptance and may incur costs to defend or settle claims with our customers.
  • Any failure to offer high-quality technical support services may harm our relationships with our customers, our brand, and our results of operations.
  • If we are unable to maintain our culture and core values 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 may not realize the anticipated benefits of our efforts to streamline operations and improve cost efficiencies, including restructuring and reorganization activities, which may be disruptive to our operations and could adversely affect our business, results of operations, and financial condition.
  • Changes in financial accounting standards or practices may cause adverse, unexpected financial reporting fluctuations and affect our results of operations.
  • If our judgments or estimates relating to our critical accounting estimates are based on assumptions that change or prove to be incorrect, our results of operations could fall below expectations of securities analysts and investors, resulting in a decline of the trading price of our Series A common stock.
  • We track and disclose certain operational metrics, which are subject to inherent challenges in measurement, and real or perceived inaccuracies in such metrics may harm our reputation and materially adversely affect our stock price, business, results of operations, and financial condition.
  • If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.
  • We face exposure to foreign currency exchange rate fluctuations, and such fluctuations could adversely affect our business, results of operations, and financial condition.
  • Changes in tax law could adversely affect our business, financial condition, and results of operations.
  • Our international operations and structure subject us to potentially adverse tax consequences.
  • Our ability to use net operating loss carryforwards to offset future taxable income for U.S. federal tax purposes is subject to limitation and risk that could further limit our ability to utilize our net operating losses.
  • We may require additional capital to support the growth of our business, and this capital might not be available on acceptable terms, if at all.
  • Partnerships, strategic investments, alliances or acquisitions could be difficult to identify, pose integration challenges, divert the attention of management, disrupt our business, dilute stockholder value, and adversely affect our business, financial condition, and results of operations.
  • Any future litigation against us could be costly and time-consuming to defend.
  • We agree to indemnify customers and other third parties pursuant to various contractual arrangements we enter into in the course of business, which exposes us to substantial potential liability.
  • We are subject to anti-corruption, anti-bribery, and similar laws, and non-compliance with these laws can subject us to criminal penalties or significant fines and adversely affect our business and reputation.
  • The effects of a pandemic, epidemic, outbreak of an infectious disease or other public health crises may materially affect how we and our partners and customers are operating our businesses, and the duration and extent of these kinds of events may impact our future results of operations and overall financial performance.
  • Risks Relating to Privacy, Data Security, and Data Protection Laws
  • We collect, process, store, share, disclose, and use personal information and other data, which subjects us to legal obligations related to privacy and security, and our actual or perceived failure to comply with these obligations could harm our business.
  • If we or our third-party service providers experience a cybersecurity incident or data breach or unauthorized parties otherwise obtain access to our customers’ data, our data, or our platform, our platform or our products may be perceived as not being secure, our reputation may be harmed, demand for our platform and products may be reduced, and we may incur significant liabilities.
  • A cybersecurity incident, data breach or other compromise may cause us to breach customer contracts. Our agreements with certain customers may require us to use industry-standard or reasonable measures to safeguard personal information or confidential information. A cybersecurity incident, data breach or other compromise could lead to claims by our customers, their end-users, or other relevant stakeholders that we have failed to comply with such legal or contractual obligations. As a result, we could be subject to legal action or our customers could end their relationships with us.
  • We are subject to stringent and changing laws and regulations related to privacy, data security, and data protection. The restrictions and costs imposed by these requirements, and our actual or perceived failure to comply with them, could harm our business.
  • We are subject to new and evolving data processing and interoperability regulations, which may increase our compliance obligations and operational complexity.
  • Federal, state, and foreign laws that regulate the senders of commercial emails and text messages could adversely affect our ability to provide our products and impact our results from operations or result in costs and fines.
  • If our platform fails to function in a manner that allows our customers to operate in compliance with regulations and/or industry standards, our business, financial condition, and results of operations could be adversely affected.
  • We could face liability, or our reputation might be harmed, as a result of the activities of our customers, the content sent through our platform (including AI-generated content) or the data they store on our servers.
  • The standards that private entities and inbox service providers use to regulate and filter the use and delivery of email may interfere with the effectiveness of our platform and our ability to conduct business.
  • Risks Relating to Our Intellectual Property
  • Any failure to protect our proprietary technology and intellectual property rights could substantially harm our business, financial condition, and results of operations.
  • In the future we may be party to intellectual property rights claims, disputes, and other litigation brought by others which are expensive to support, and if resolved adversely, could have a significant impact on us.
  • Our use of open source software could negatively affect our ability to sell our products and subject us to possible litigation.
  • Our use of AI technology and the integration of AI technology with our products and services may subject us to increased risk, including security and other risks to our confidential and/or proprietary information, given the evolving nature of AI technology.
  • Risks Relating to Ownership of Our Series A Common Stock
  • Our IPO occurred in September 2023. As such, there has only been a public market for our Series A common stock for a short period of time. The trading price of our Series A common stock may continue to be volatile or may decline regardless of our operating performance, and you may not be able to resell your shares at or above the price at which you purchased those shares.
  • We cannot predict the effect our dual series structure may have on the trading price of our Series A common stock.
  • If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, the trading price of our Series A common stock and trading volume could be adversely affected.
  • Sales of substantial amounts of our Series A common stock in the public markets, or the perception that sales might occur, could cause the trading price of our Series A common stock to decline.
  • Our issuance of additional capital stock in connection with financings, acquisitions, investments, our stock incentive plans, or otherwise will dilute all other stockholders and could negatively affect our results of operations.
  • We do not intend to pay dividends on our Series A common stock in the foreseeable future and, consequently, the ability of Series A common stockholders to achieve a return on investment will depend on appreciation in the trading price of our Series A common stock.
  • Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate. Even if the markets in which we compete achieve the forecasted growth, our business could fail to grow at similar rates, if at all.
  • Provisions in our charter documents and under Delaware law could make an acquisition of our company more difficult, limit attempts by our stockholders to replace or remove our current board of directors, and limit the trading price of our Series A common stock.
  • Our amended and restated bylaws designate specific courts as the exclusive forum for certain litigation that may be initiated by our stockholders, which could potentially limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us and may discourage lawsuits against us and our directors, officers, and employees.
  • General Risk Factors
  • We have incurred, and we will continue to incur, increased costs as a result of operating as a public company, and our management is required to devote substantial time to support compliance with our public company responsibilities and corporate governance practices.
  • Adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect our current and projected business operations, financial condition, and results of operations.
  • Climate change may have a long-term impact on our business.

Legal proceedings

From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not currently a party to, nor is our property currently subject to, any material legal proceedings, nor are we involved in any legal proceedings the outcome of which we believe would have a material adverse effect on our financial condition or results of operations based on the status of the proceedings at this time. We are not aware of any governmental inquiries or investigations into our business.
