From a Faster Pipe to a Smarter Network
Founded in 2011, Fastly made its name as a modern Content Delivery Network (CDN). The basic job of a CDN is simple: it stores copies of website content (like images and videos) on servers around the world, physically closer to users. When you visit a site,
the content loads from a nearby server, making the experience much faster. For years, this was a game of speed and volume. Fastly competed with giants like Akamai by offering developers more control and faster updates. While successful, this core business, known as 'delivery', is largely a usage-based commodity. Customers pay for the amount of data they move, and competition can be fierce. To truly break away from the pack, Fastly needed something more than just a faster pipe.
The Billion-Dollar Bet on the Edge
The strategic pivot was to go all-in on 'edge computing'. Think of it like this: if a traditional CDN is a global network of libraries for storing content, edge computing adds a mini-production studio to each library. Instead of just delivering a static file, the network can now run code and make decisions 'at the edge', before the data ever reaches a centralized server. Fastly's big bet was its Compute@Edge platform, a serverless environment that allows developers to build and execute complex applications directly on its global network. This was a fundamental shift. The company was no longer just delivering content; it was offering a distributed computer that could power dynamic, real-time digital experiences. It was a wager that the future of the internet wasn't just about speed, but about intelligence.
Higher Margins and Stickier Customers
This bet is what unlocked a new, more profitable era for the company. While core network services still account for the majority of revenue, higher-value services like security and compute are the growth engines. These services command higher margins because they are less of a commodity than bandwidth. A company might switch CDNs to save money on data transfer, but it’s much harder to rip out security and custom application logic that is deeply integrated into the network. This 'land-and-expand' strategy is working: Fastly has seen a surge in customers adopting multiple products. In its third-quarter 2026 earnings, Fastly reported record non-GAAP gross margins of 65.8% and its fifth consecutive quarter of operating profit, driven by the adoption of these higher-value services.
AI and the Future of the Edge
The bet on edge computing looks even smarter with the explosion of artificial intelligence. AI applications, especially those involving real_time analysis and agentic traffic (automated bots and agents), require immense processing power with minimal delay. Performing this work at the edge is far more efficient than sending vast amounts of data back to a central cloud. Fastly has reported that AI_related workloads are a significant tailwind, with its 'Other' revenue category, which includes Compute, soaring in 2026. The company is now actively co_innovating with AI firms, positioning its network as essential infrastructure for the next generation of intelligent applications. However, the strategy isn't without risk. The market is intensely competitive, with Cloudflare and Amazon Web Services also investing heavily in edge capabilities. Furthermore, Fastly has a notable concentration of revenue among its top 10 customers, a vulnerability it must address by broadening its customer base.
