AI agent cloud startup Daytona raised $60 million at a $1 billion valuation, Fortune and TechCrunch reported. FirstMark led the Series B. The round brings Daytona's total funding to about $91 million.

Fortune said cofounder and CEO Ivan Burazin is building a cloud meant for AI agents that need their own computers or sandboxes. Agents that write code, browse the web or run business software often need a machine that keeps running when a user's laptop sleeps, Fortune reported. A sandbox can also limit what the agent can touch.

TechCrunch said Daytona Platforms announced the round on Friday and that FirstMark also led its $24 million Series A in February. Angels named in the round include Stripe's Patrick Collison, Shopify's Tobi Lütke, Perplexity's Aravind Srinivas, Zoom's Eric Yuan and Quora's Adam D'Angelo. Qualcomm Ventures, Samsung Next and Okta Ventures also took part, Fortune and TechCrunch reported.

Burazin said about $50 million of the new round came from existing investors, Fortune reported. He wrote that agents spin up many short, stateful jobs that older cloud designs did not plan for, TechCrunch reported. Daytona says agents can get sandboxed Linux, Windows, macOS and GPUs on one platform.

Fortune said Daytona began in 2023 building software development environments, then rebuilt around agent needs. Fortune places the company in San Francisco. TechCrunch describes it as New York-based. The gap is not resolved in the cited stories. Burazin also said older cloud designs were built for long-lived services, not for thousands of short agent jobs.

What we know: Daytona raised $60 million at a $1 billion valuation led by FirstMark, bringing total funding to about $91 million.
What we don't: How soon revenue will match the new valuation, or which large customers are live on the agent cloud.
