Daytona hits $1B valuation in $60M Series B led by FirstMark

Its sandboxes cost more than AWS per hour, betting that millisecond startup speed matters more than price for AI agents.

• Daytona Platforms raised a $60 million Series B at a $1 billion valuation, led by FirstMark Growth, bringing total funding to $91 million.
• The three-year-old startup builds an 'agent execution cloud' that gives each AI agent its own isolated sandbox across Linux, Windows, macOS and GPUs.
• About $50 million of the round came from existing backers deepening their bets, with Pace Capital doubling, Upfront Ventures tripling and E2VC quadrupling their prior investments.
• Daytona's revenue run rate grew roughly 25x between January and September 2026, with net revenue retention around 135% and one customer spinning up 300,000 environments in a single month.
• Founded in 2023 to automate dev environments, Daytona rebuilt itself in 2025 around AI agent infrastructure after seeing demand shift, and now counts Anthropic, OpenAI, Nvidia, Cursor, Cognition, Meta and Cohere as customers.
• Daytona's list prices run about 68% above AWS Fargate per compute-second, meaning its economics depend on agents needing to spin up and tear down machines in seconds rather than minutes.
• The round underscores investors' conviction that autonomous AI agents require a new infrastructure layer distinct from the servers and containers built for human-run software.
