Daytona Platforms said Friday it raised a $60 million Series B round at a $1 billion valuation, with FirstMark Growth leading the investment. The New York-based startup said the new funding brings its total raised to $91 million. FirstMark also led Daytona's $24 million Series A in February.
The round drew a long list of prominent angel investors, according to Daytona. They include Stripe's Patrick Collison, Shopify's Tobi Lütke, Perplexity's Aravind Srinivas, Zoom's Eric Yuan, Datadog's Olivier Pomel, Quora's Adam D'Angelo, who is also an OpenAI board member, and Mercor's Brendan Foody. Qualcomm Ventures, Samsung Next, and Okta Ventures also participated, the company said.
Daytona, which is three years old, is building a cloud environment designed specifically for long-running agents. The company argues that these agents have infrastructure needs that differ from the software the existing cloud was built to serve. In a blog post announcing the round, founder Ivan Burazin wrote that agents do not operate like the long-lived services today's cloud was designed for. He said they spin up thousands of short, stateful jobs that nobody planned in advance, and that they need a cloud built for that pattern.
According to Burazin, Daytona's cloud gives each agent its own computer. Agents get access to sandboxed versions of Linux, Windows, macOS, and GPUs, among other services, all on one platform, he said.
The valuation places the three-year-old company among startups attracting large checks for AI infrastructure. Daytona's pitch centers on the idea that agent workloads, with their many short, stateful jobs, do not fit neatly into cloud services built for long-running applications. The company says its platform is intended to handle that workload directly rather than adapting existing cloud offerings to it.
The angel list spans leaders of payments, commerce, search, videoconferencing, observability, and question-and-answer platforms, along with an OpenAI board member. The participation of Qualcomm Ventures, Samsung Next, and Okta Ventures adds corporate venture arms to the investor base.
Daytona's total funding now stands at $91 million, following the February Series A and the newly announced Series B. FirstMark Growth led both rounds, according to the company.
