On October 20, 2026, Daytona announced a $60 million Series B at a $1 billion valuation, led by FirstMark Growth, bringing its total funding to $91 million. Individual investors included Patrick Collison, Tobi Lutke, Aravind Srinivas, Eric Yuan, Olivier Pomel, Adam D’Angelo and Brendan Foody, and strategic investors included Qualcomm Ventures, Samsung Next and Okta Ventures.
Daytona sells sandboxes: isolated computers in which AI agents run code, use tools and operate desktops. The post, by CEO Ivan Burazin, argues that an agent computer must “start in milliseconds, pause with its state intact, fork into parallel copies,” and claims “Daytona is the only provider with Linux, Windows, macOS, and GPU sandboxes on one platform.”
The company said revenue has grown about 25 times since January and that average month-over-month net revenue retention is about 135%. Named customers include model builders Meta and Cohere; training-data and environment companies Handshake, Snorkel, Surge AI and Turing; and products such as Writer, Clay, n8n, Postman and bolt.new. Writer, it said, provisioned 300,000 sandboxes on Daytona in a single month.
Why it matters: coding agents, computer-use agents and reinforcement learning all need large numbers of disposable, safe machines. Daytona’s round, a week after Modal disclosed a $300 million run-rate sandbox business, shows agent infrastructure becoming its own funded market layer.
What it does not show: Daytona discloses growth multiples but not absolute revenue, so the 25x figure may start from a small base. The single-platform claim is the company’s own and was not independently tested.
