The Thesis
Summary
Cloudflare is a cloud software company that makes the internet faster and more secure for millions of websites. It generated $2.32 billion in revenue over the last twelve months, growing its top line by 33% in the most recent quarter. While it spent years investing heavily to build a global network that now spans more than 330 cities, the business has reached a point where it can finally generate significant cash, producing $320 million in free cash flow last year.
The core bet on Cloudflare is that its massive network of 237,714 paying customers provides the foundation to win the next decade of "edge computing," where AI and software run on Cloudflare's servers instead of a distant data center. The company is successfully moving from being a simple security tool to a full-scale computing platform through its Workers and Zero Trust products. If it continues to capture a larger share of enterprise spending, it will become as essential to the internet as the major cloud providers. More specifically, four things need to be true:
We think Cloudflare is an exceptional business that is currently far too expensive for new investors to touch. While the underlying growth and cash generation are impressive, the stock price has run so far ahead of its actual earnings that it already assumes years of perfect execution. One small slip in growth would likely lead to a sharp correction in the stock price.
Numbers at a Glance
What does it do?
Cloudflare is a hypergrowth business that earns money by selling subscriptions to its global network that sits between a website's server and its users. When a company uses Cloudflare, its traffic flows through Cloudflare's data centers in 330 cities, which automatically block cyberattacks, filter out bots, and speed up content delivery by storing files closer to the user. Customers pay a monthly or annual fee for different tiers of service: individuals can use a free version, while businesses pay for "Pro" or "Business" plans. Large enterprises sign custom contracts based on the specific security and computing features they use, such as the "Workers" platform that lets developers run code directly on Cloudflare's network.
Where does revenue come from?
The vast majority of revenue comes from recurring subscriptions for security and performance services. Cloudflare earns most of its money from enterprise contracts, with large customers who spend over $100,000 annually contributing about 69% of its total sales. While the company provides some services to individuals, its growth is driven by these high-value business clients. Its geographic mix is diverse, with more than 40% of its revenue typically coming from outside the United States.
Revenue by Geography
Who are its customers?
Cloudflare serves 237,714 paying customers, ranging from small personal blogs to nearly 3,500 large enterprises. These clients include roughly 30% of the Fortune 500, who rely on the company to prevent outages and protect against data breaches. The customer base is split between two distinct groups: the "long tail" of hundreds of thousands of small users who provide a massive testing ground for new products, and a top-heavy group of 173 "super-large" customers who each spend more than $1 million per year. Large customer growth has been a major highlight, as this group increased by over 30% in the most recent fiscal year.
What gives it staying power?
Cloudflare's staying power comes from the high switching costs of moving a company's entire security and networking setup. Once a business routes its traffic through Cloudflare, the complexity of untangling those integrations makes leaving difficult. Its massive global network also creates a "data moat": as it blocks attacks for one site, it learns how to protect all its other customers.
Where is it headed?
The company is making its biggest bet on AI inference, placing high-end graphics chips in every one of its data centers worldwide. By doing this, Cloudflare wants to become the place where companies run their AI models, arguing that AI should live "at the edge" near the user rather than in a few giant data centers. If successful, this moves Cloudflare from being a security filter to becoming the fundamental engine for the next generation of AI apps.
Revenue growth remains the standout feature as the company scales efficiently toward its next billion in sales. Revenue reached $640 million in the most recent quarter, up 33% from the prior year, proving that demand for internet security is highly resilient even in uncertain markets.
Free cash flow has reached a sustainable positive level, marking a major turning point for the business model. The company generated $320 million in free cash flow last year, which represents about 15% of its revenue. This proves Cloudflare can fund its own massive network expansions without needing to raise more money from outside investors.
The balance sheet is incredibly strong with a significant cash cushion that provides a safety net for future growth. Cloudflare holds more than $1.7 billion in cash and short-term investments, which easily covers its debt and gives it the flexibility to buy smaller companies or invest more heavily in AI hardware.
Cloudflare is a high-growth machine that has finally proven it can generate real cash while expanding at a rapid clip.
The move upmarket is working perfectly, with large customers now making up 69% of all revenue. This shift away from small, cheap accounts toward massive enterprise contracts makes the business much more stable and predictable. It also shows that Cloudflare is winning the trust of the world's largest companies for their most critical infrastructure.
The biggest risk is that Cloudflare's "Workers" and AI products face intense competition from established giants like Amazon and Microsoft. While Cloudflare is faster, the "big three" cloud providers have massive existing relationships and can bundle computing for free. If Cloudflare cannot convince developers that its network is a better home for their code than AWS, its growth runway will be much shorter than investors expect.
The cloud security and edge computing market is roughly $100 billion today and is growing at nearly 20% annually, on track to exceed $250 billion by 2029. It is an exceptionally attractive industry because security is a "must-have" expense that companies rarely cut, giving providers significant pricing power. Cloudflare stands as the primary challenger to traditional networking, positioning itself as a "software-defined" alternative to the expensive hardware that companies used to buy from companies like Cisco.
This market is highly competitive but is gradually consolidating around a few platforms that can do everything. Barriers to entry are high because building a global network with 330 data centers requires billions of dollars and years of complex engineering.
Akamai(AKAM) remains the largest incumbent, but Cloudflare's software-first approach is faster and easier for developers to use. The most dangerous threat is Zscaler, which has a deeper hold on large enterprise "Zero Trust" security and is competing head-to-head for the same billion-dollar corporate security budgets. While Amazon and Microsoft offer similar tools, they are often seen as "lock-in" risks, whereas Cloudflare is used as a neutral layer that works across all clouds.
Cloudflare is clearly gaining market share, with its large customer count growing 30% last year. This growth is coming directly at the expense of legacy hardware vendors and slower-moving competitors like Akamai.
Cloudflare's primary protection comes from high switching costs. Once a company routes its global internet traffic and security rules through Cloudflare's servers, moving to a competitor is a high-risk operation that can cause major outages. The company's 77.3% gross margin proves it has significant leverage over its costs and can maintain high prices while scaling.
The combination of a 77% gross margin and 33% growth proves this is a high-quality business, but the negative ROIC shows it is still spending every dollar it makes to grow. While it has a real advantage, it is currently more of a "good business" than a "wide moat" because it must still spend heavily on sales to win each new contract.
The moat is strengthening as the network grows larger, with the rollout of AI hardware making it even harder for customers to leave. Cloudflare is successfully turning its simple security filter into an essential computing platform.
