Fly.io has raised $25 million in Series D funding co-led by Dell Technologies Capital and Intel Capital to build the next generation of AI infrastructure purpose-built for agents. The company is pivoting to "computers for agents"—connected infrastructure that gives AI agents real computers with durable storage, secure connectivity, and the ability to scale to millions of instances for production AI applications .
Fly.io raised $25M Series D co-led by Dell Technologies Capital and Intel Capital, with participation from Andreessen Horowitz, EQT, Geodesic, and YC .
Scott Johnston, former CEO of Docker, appointed as CEO and board member; founder Kurt Mackey transitions to advisory role .
Agent-native customers now represent approximately two-thirds of revenue among Fly.io's largest customers .
Revenue from largest agent-native customers grew nearly 12x over the past 12 months .
More than 37,000 customers build on Fly.io, with over 8,000 being agent-native .
Agent-first companies like Firecrawl, Kilocode, and Plastic Labs use Fly.io for production AI applications .
AI agents are transforming how software is built and deployed. For nearly a decade, Fly.io has helped developers build and run software. Now, as agents increasingly build, operate, and deploy software alongside people, Fly.io recognizes that AI agents require a fundamentally different kind of infrastructure than the disposable execution environments that defined the first wave of AI .
Fly.io is doubling down on computers for agents — connected infrastructure designed for AI agents and the applications they build. Fly.io gives agents real computers that have durable disk drives, secure connectivity to other systems, and the ability to scale to millions of instances to power production AI applications .
Fly.io just closed its strongest quarter in company history, driven almost entirely by agent workloads. More than 37,000 customers build on Fly.io, and more than 8,000 of them are agent-native. Over the past 12 months, revenue from the company's largest agent-native customers has grown nearly 12 times. Among the company's largest customers overall, agent-native companies now represent approximately two-thirds of revenue .
To accelerate this opportunity, Fly.io announced $25 million in Series D funding co-led by Dell Technologies Capital and Intel Capital, with participation from Andreessen Horowitz, EQT, Geodesic, and YC. Martin Casado, general partner at Andreessen Horowitz, and Daniel Docter, managing director at Dell Technologies Capital, will join the company's board of directors .
Fly.io also announced that Scott Johnston has joined as CEO and a member of the board. Johnston previously served as CEO of Docker and held leadership roles at Puppet, Loudcloud, and Netscape, helping scale infrastructure platforms through major shifts in software development. Founder Kurt Mackey will remain on Fly.io's board and transition to an advisory role, continuing to help shape the company's long-term technical vision .
"We evaluated a number of platforms for running agents, but Fly was the only one that treated long-running, stateful compute as a first-class primitive rather than something bolted on," said Moin Nadeem, co-founder of Phonic. "Being able to run agent environments close to data and inference is exactly the foundation our product depends on" .
"Every wave of infrastructure is defined by who its primary user is, and for the first time that user isn't necessarily a person. That changes what a computer has to look like," said Martin Casado, general partner at Andreessen Horowitz. "Fly has spent years building infrastructure for that shift and is giving agents real computers instead of disposable sandboxes" .
"Every platform shift looks obvious in hindsight and contested in the moment — and having seen a few up close, this has the same shape. Agents — the new interface for people — need real computers of their own," said Scott Johnston, CEO of Fly.io. "Fly has been building toward this for years, and I joined to help build the category and scale the company driving it" .
