The story

Founding and IPO (2011–2019)

Fastly was founded in 2011 by the Swedish-American entrepreneur Artur Bergman, previously chief technical officer at Wikia (now Fandom). In June 2013, Fastly raised $10 million in Series B funding. In April 2014, the company announced that it had acquired CDN Sumo, a CDN add-on for Heroku. In September 2014, Fastly raised a further $40 million in Series C funding, followed by a $75 million Series D round in August 2015.

In September 2015, Google partnered with Fastly and other content delivery network providers to offer services to its users. In April 2017, Fastly launched its edge cloud platform along with image optimization, load balancing, and a web application firewall.

Fastly raised $50 million in funding in May 2017, and another $40 million in July 2018. The company filed for an initial public offering (IPO) in April 2019 and debuted on the New York Stock Exchange on May 17, 2019.

Joshua Bixby as CEO (2020–2022)

In February 2020, Bergman stepped down as CEO and assumed the role of chief architect and executive chairperson; Joshua Bixby took over the CEO role.

In August 2020, Fastly announced it was acquiring cybersecurity company Signal Sciences for $775 million ($200 million in cash and $575 million in stock).

In June 2021, Ronald W. Kisling, previously employed by Alphabet as the CFO of the Fitbit division, was hired to serve as Fastly's CFO, succeeding Adriel Lares. He assumed the position in August 2021.

On 8 June 2021, a software bug in Fastly's CDN, triggered by a valid customer configuration change, temporarily disrupted access to major websites, including Reddit, Twitch, Amazon, GOV.UK, The New York Times, The Guardian, and the BBC. According to Fastly, 95% of its network was operating normally within 49 minutes. The incident prompted discussion about the internet's reliance on a small number of CDN providers.

In May 2022, Fastly announced it had acquired Glitch, a web coding platform with more than 1.8 million developers.

Products and brands

Fastly provides content delivery, edge computing, security, and observability services.

Content delivery

Fastly operates a content delivery network (CDN) that caches web content, delivers live and on-demand video, and serves application programming interface (API) responses through geographically distributed points of presence. Its CDN follows a reverse-proxy model, routing requests through Fastly's servers. Content is retrieved from customers' origin servers and cached to reduce the time required for users to access it. Fastly also offers semantic caching through its AI Accelerator, which caches responses to similar AI prompts to reduce latency and API calls.

The platform supports static and dynamic content delivery, configurable caching rules, and instant purging, which allows customers to invalidate cached content across the network. According to Fastly, its mean global cache purge time was less than 150 milliseconds as of December 31, 2025.

Fastly supports the UDP-based HTTP/3 protocol, as well as digital rights management (DRM)-enabled content, encryption, and secure tokens to restrict media access. Its caching infrastructure uses a heavily modified version of Varnish. Fastly's network map listed 622 Tbps of connected global capacity as of June 30, 2026.

Edge computing

Fastly Compute, formerly called Compute@Edge, is a serverless edge computing platform that runs application code on Fastly's distributed network. It uses a WebAssembly (Wasm) runtime based on Wasmtime to execute code in isolated sandboxed environments close to end users. By default, each request starts a new sandbox.

Fastly also co-founded the Bytecode Alliance, an organization supporting the development of WebAssembly technologies.

Developers can write Compute applications in languages including JavaScript, Rust, C++, and Go. Support for other languages depends on compatibility with WebAssembly and the platform's interfaces.

Fastly provides key-value and object storage services for applications using its platform, alongside Fanout for real-time publish-subscribe messaging.

Security

Fastly provides web application security, API discovery and enforcement, bot management, and protection against distributed denial-of-service (DDoS) attacks. Its Next-Gen web application firewall (WAF) is based on technology from Signal Sciences, which Fastly acquired in 2020. The firewall analyzes HTTP requests and applies detection signals and rules to identify and block attacks such as SQL injection and cross-site scripting.

In 2024, Fastly introduced Bot Management, which classifies automated traffic at the network edge and provides controls to allow, challenge, or block bots. Fastly also offers API Security, Client-Side Protection, and DDoS Protection.

In 2025, Fastly reported that its Next-Gen WAF and Bot Management products protected more than 130,000 applications and APIs and inspected over 6.5 trillion requests per month.

Observability

Fastly provides observability tools for monitoring traffic, performance, and security events on its network. These include real-time log streaming to external analytics platforms and security information and event management (SIEM) systems. Its monitoring tools include Custom Dashboards, Log Explorer & Insights, Domain Inspector, and Origin Inspector.

Research

Fastly publishes security research based on traffic observed through its services, including analyses of AI crawlers and other automated requests. A 2025 report attributed 95% of the AI crawler traffic in its dataset to Meta, Google, and OpenAI. A report published in 2026 found that bots accounted for 49% of the requests analyzed during January of that year and classified 99% of that bot traffic as unwanted or unverifiable.

Risk factors and legal proceedings

The risks Fastly names in Item 1A of its 10-K filed Feb 25, 2026: 74 risks under these headings, as written.16

  • Risks Related to Our Business, Industry and Technology
  • If our platform fails to perform properly due to defects, interruptions, outages, delays in performance, or similar problems, and if we fail to develop enhancements to resolve any defect, interruption, delay, or other problems, we could lose customers, become subject to service performance or warranty claims, or incur significant costs.
  • If we are unable to attract new customers, in particular, enterprise customers, and to have existing enterprise customers continue and increase their use of our platform, our business will likely be harmed.
  • We receive a substantial portion of our revenues from a limited number of customers within a limited number of industries, and the loss of, or a significant reduction in usage by, one or more of our major customers would result in lower revenues and could harm our business.
  • Component delays, shortages, or price increases could interrupt our ability to complete the construction of our servers or POPs and to meet the usage needs of our customers. Our operating results could be materially harmed if we are unable to adequately manage our infrastructure needs.
  • Our history of operating losses makes it difficult to evaluate our current business and prospects and may increase the risks associated with your investment.
  • If our IT Systems or data, or those of third parties upon which we rely, are compromised, limited, or fail, our business could experience materially adverse consequences, including but not limited to regulatory investigations or actions, litigation, fines and penalties, disruptions of our business operations, loss of revenue or profits, loss of customers or sales, reputational harm, and other adverse consequences.
  • If we fail to efficiently develop and sell new products and respond effectively to rapidly changing technology, evolving industry standards, changing regulations, and changing customer needs, requirements, or preferences, our products may become less competitive.
  • If we fail to forecast our revenue accurately, or if we fail to manage our expenditures, our operating results could be adversely affected.
  • 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.
  • The markets in which we participate are competitive, and if we do not compete effectively, our business will be harmed.
  • If we fail to maintain and enhance our brand, our ability to expand our customer base will be impaired and our business, results of operations and financial condition may suffer.
The other 63 risks
  • Acquisitions, strategic investments, partnerships, or alliances could be difficult to identify and integrate, divert the attention of management, disrupt our business, and dilute stockholder value.
  • We are, and may in the future be, involved in class-action lawsuits and other litigation matters that are expensive and time-consuming. If resolved adversely, lawsuits and other litigation matters could seriously harm our business.
  • We may not be able to scale our business quickly enough to meet our customers’ growing needs. If we are not able to grow efficiently, our business could be harmed.
  • We may have insufficient transmission bandwidth and colocation space, which could result in disruptions to our platform and loss of revenue.
  • The nature of our business exposes us to inherent liability risks.
  • Our dedication to our values may negatively influence our financial results.
  • Our growth depends in large part on the success of our partner relationships.
  • We operate in an emerging and evolving market, which may develop more slowly or differently than we expect. If our market does not grow as we expect, or if we cannot expand our services to meet the demands of this market, our revenue may decline, or fail to grow, and we may incur operating losses.
  • The estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and any real or perceived inaccuracies may harm our reputation and negatively affect our business. Even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.
  • Usage of our platform accounts for substantially all of our revenue, and as a result, our operating results could suffer from a reduction in usage.
  • We expect fluctuations in our financial results and key metrics, making it difficult to project future results, and if we fail to meet the expectations of securities analysts or investors, our stock price and the value of your investment could decline significantly.
  • Our pricing models subject us to various challenges that could make it difficult for us to derive sufficient value from our customers, and we do not have sufficient history with our pricing models to accurately predict the optimal pricing necessary to attract new customers and retain existing customers.
  • Our sales and onboarding cycles with customers can be long and unpredictable, and our sales and onboarding efforts require considerable time and expense.
  • If our platform does not achieve sufficient market acceptance, our financial results and competitive position will suffer.
  • We rely on third-party providers that may be difficult to replace.
  • Our business is exposed to risks associated with credit card and other online payment processing methods.
  • If we do not or cannot maintain the compatibility of our platform with third-party applications that our customers use in their businesses, our business will be harmed.
  • We provide service level commitments under our customer agreements. If we fail to meet these contractual commitments, we could be obligated to provide credits for future service, or face contract termination with refunds of prepaid amounts, which could harm our business.
  • If we fail to offer high quality support, our business may be harmed.
  • Scrutiny relating to environmental, social and governance factors may impose additional costs and expose us to new risks.
  • Risks Related to Employees and Managing Our Growth
  • The failure to attract and retain qualified personnel could prevent us from executing our business strategy.
  • We rely on the performance of highly skilled personnel, including our senior management and other key employees, and the loss or transition of one or more of such personnel, or of a significant number of our team members, could harm our business.
  • Our past growth may not be indicative of our future growth and we may not be able to manage our growth effectively.
  • If we cannot maintain our company culture as we grow, our success and our business may be harmed.
  • Risks Related to Our Financial Position and Need for Additional Capital
  • Our ability to timely raise capital in the future may be limited, or may be unavailable on acceptable terms, if at all, and debt or equity issued to raise additional capital may reduce the value of our common stock.
  • Seasonality may cause fluctuations in our sales and operating results.
  • Our current operations are international in scope and we plan on further geographic expansion, creating a variety of operational challenges.
  • If our estimates or judgments relating to our critical accounting estimates prove to be incorrect, our results of operations could be adversely affected.
  • Current and future indebtedness could restrict our operations, particularly our ability to respond to changes in our business or to take specified actions.
  • If we are unable to 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 common stock may be seriously harmed.
  • We may not be able to successfully manage the growth of our business if we are unable to improve our internal systems, processes and controls.
  • Our financial results may be adversely affected by changes in accounting principles applicable to us.
  • Risks Related to Laws, Regulations, and the Global Economy
  • Failure to comply with United States and foreign governmental laws and regulations could harm our business.
  • Regulatory and legislative developments on the development and deployment of AI technologies could adversely affect our use of such technologies in our business operations or our products and services.
  • Activities of our customers or the content of their websites and other Internet properties may violate applicable laws and/or our terms of service and could subject us to lawsuits, regulatory enforcement actions, reputational harm, and/or liability in various jurisdictions.
  • Our sales to highly regulated organizations and government entities are subject to a number of challenges and risks.
  • The success of our business depends on customers’ continued and unimpeded access to our platform on the Internet.
  • We are subject to anti-corruption, anti-bribery, anti-money laundering and similar laws, and non-compliance with such laws can subject us to criminal and/or civil liability and harm our business.
  • Changes in our effective tax rate or tax liability may harm our business.
  • We could be required to collect additional sales taxes or be subject to other tax liabilities that may increase the costs our clients would have to pay for our offering and harm our business.
  • Adverse tax laws or regulations could be enacted or existing laws could be applied to us, which could adversely affect our business and financial condition.
  • Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.
  • Our international operations may subject us to potential adverse tax consequences.
  • We are subject to governmental export and import controls that could impair our ability to compete in international markets or subject us to liability if we violate such controls.
  • We are exposed to fluctuations in currency exchange rates.
  • Unfavorable conditions in our industry or the global economy, rising inflation or reductions in information technology spending could harm our business.
  • Risks Related to Intellectual Property
  • We could incur substantial costs in protecting or defending our intellectual property and proprietary rights, and any failure to adequately protect our rights could impair our competitive position and we may lose valuable assets, experience reduced revenue, and incur costly litigation to protect our rights.
  • We may in the future be subject to legal proceedings and litigation relating to 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.
  • Elements of our platform and our products use open source software, which may restrict the functionality of our platform and our products, or require that we release the source code of certain products subject to those licenses.
  • Provisions in various agreements potentially expose us to substantial liability for intellectual property infringement, data protection, and other losses.
  • Risks Related to Ownership of Our Common Stock
  • Our stock price is volatile, and the value of our common stock may decline.
  • We may not have the ability to raise the funds necessary to repay or settle conversions of the Notes in whole or in part in cash or to repurchase the Notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the Notes.
  • Conversion of the Notes may dilute the ownership interest of our stockholders or may otherwise depress the price of our common stock.
  • Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.
  • Regulatory actions and other events may adversely affect the trading price and liquidity of the Notes.
  • The conditional conversion feature of the Notes, if triggered, may adversely affect our financial condition and operating results.
  • Future sales and issuances of our capital stock or rights to purchase capital stock could result in dilution of the percentage ownership of our stockholders and could cause the price of our common stock to decline.
  • Future sales of our common stock in the public market could cause the market price of our common stock to decline.
  • If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, our common stock price and trading volume could decline.
  • We do not intend to pay dividends for the foreseeable future.
  • We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to compliance with our public company responsibilities and corporate governance practices.
  • Anti-takeover provisions in our charter documents, the indenture governing the Notes, 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 or management and limit the market price of our common stock.
  • Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware and, to the extent enforceable, the federal district courts of the United States of America will be the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.
