Daytona has raised a $60 million Series B round at a $1 billion valuation, becoming the newest AI infrastructure startup to reach unicorn status. The round was led by FirstMark Growth and brings the company’s total funding to $91 million.
A round packed with tech founders
The startup pulled in an unusually star-studded group of angel investors for this round. The list includes Stripe co-founder Patrick Collison, Shopify CEO Tobi Lutke, Perplexity CEO Aravind Srinivas, Zoom founder Eric Yuan, Datadog CEO Olivier Pomel, Quora CEO Adam D’Angelo, and Mercor co-founder Brendan Foody. Qualcomm Ventures, Samsung Next, and Okta Ventures joined as strategic investors.
FirstMark also led Daytona’s $24 million Series A in February, and existing investors including E2VC, Upfront Ventures, and Pace Capital increased their stakes. New institutional backers include Evergreen Fund, Alumni Ventures, and Torch Capital.
Computers for agents, not humans
Daytona builds isolated cloud environments, or sandboxes, where AI agents can run code, use tools, and complete tasks without touching a company’s own systems. Founder and CEO Ivan Burazin argues that agents need fundamentally different infrastructure than traditional software.
Agents don’t work like the long-lived services today’s cloud was designed for. They spin up thousands of short, stateful jobs nobody planned in advance, and they need a cloud built for that.
— Ivan Burazin, co-founder and CEO of Daytona
The company says its platform gives every agent its own computer, with sandboxed Linux, Windows, macOS, and GPU environments on a single platform. A new environment spins up in 60 milliseconds, compared with the minutes a traditional virtual machine can take to boot.
We believe the next infrastructure shift is from human-centric cloud primitives to agent-native ones.
— Matt Turck, partner at FirstMark
Revenue up 25x since January
Daytona says its revenue has grown about 25 times since January, with average month-over-month net revenue retention of roughly 135 percent. Its customers span model builders like Meta and Cohere, data companies such as Snorkel and Surge AI, and product teams at firms including Writer, Clay, n8n, and Postman.
The company plans to use the fresh capital to expand its go-to-market team and hire more engineers in San Francisco. The round also marks a milestone for Croatia’s startup scene, where Daytona runs much of its engineering from Split and Zagreb, making it the country’s third unicorn after Infobip and Rimac.
