About Daytona
Daytona sells sandboxes: isolated cloud computers where AI agents can run code, use software and train. Developers start one through an API in under 90 milliseconds, and can pause it, save a snapshot of it or fork it into a copy. Customers pay by the second for the CPU, memory, storage and GPUs they use. Sandboxes can run Linux, Windows or macOS.
Its customers include Meta, Cohere, Writer, Clay, Snorkel and Postman, and Fortune reports that Anthropic, OpenAI and Nvidia are customers too. Daytona lists its office in New York, but most of its engineers work in Split and Zagreb, Croatia, according to The Recursive. It now also hires for its San Francisco office. It has about 30 employees, according to TNW. Ivan Burazin (CEO), Vedran Jukić (CTO) and Goran Draganić (chief architect) founded it in 2023.

Why Investors Backed Daytona
Investors backed Daytona because AI agents need their own computers, and today's cloud suits them poorly. Daytona rents out sandboxes that start in milliseconds, keep their state and split into parallel copies. Daytona's revenue has risen about 25-fold since January 2026. FirstMark led its last two rounds, the latest at a $1 billion valuation.
The problem it targets
AI agents work differently from the web services that today's cloud mostly runs. They install packages, run tests, fail and retry, often in thousands of short jobs at once. Matt Turck of FirstMark wrote that virtual machines are "heavy and expensive to keep warm," while serverless tools keep no state. Fortune reports that a new virtual machine on AWS, Azure or Google Cloud takes 30 seconds to many minutes to start. Many customers first built their own sandboxes. Writer did until it passed 20,000 sandboxes a day and upkeep became a full-time job.
What the product does
Developers create a sandbox with a few lines of code, through Daytona's API or SDKs. Each sandbox is a full computer with its own CPU, memory, disk and operating system. Agents can pause it, snapshot it, or fork it into parallel copies. Daytona offers Linux, Windows, macOS and GPU sandboxes on one platform. Customers can also run sandboxes in their own cloud, with Daytona as the control plane. Billing is per second, and a vCPU costs about $0.05 an hour.
Progress so far
Daytona reached a $1 million forward revenue run rate in under three months, then doubled it in six weeks. By October, Daytona's average monthly net revenue retention was about 135%. CEO Ivan Burazin told TNW the company has grown almost 51% a month for 18 months, with no salespeople. About 70% of revenue comes from post-training, where AI labs and data companies train agents, he said. Customers include Meta, Cohere, Snorkel, Writer and Postman, and Fortune adds Anthropic, OpenAI and Nvidia.
Who backs it
FirstMark Growth led the $60 million Series B in October 2026, and about $50 million came from existing investors, Burazin told Fortune. Angels include Patrick Collison of Stripe, Tobi Lütke of Shopify and Aravind Srinivas of Perplexity. Qualcomm Ventures, Samsung Next and Okta Ventures joined as strategic investors. FirstMark Capital led the $24 million Series A in February 2026, with Pace Capital, Upfront Ventures, E2VC, Datadog and Figma Ventures. Upfront led the 2024 seed round. Matt Turck of FirstMark and Kevin Zhang of Upfront are directors.
How the market is moving
Rivals have raised large sums. Modal raised $750 million at a $15.75 billion valuation in October 2026. Nearly a third of its revenue comes from sandboxes, SiliconANGLE reported. E2B, which also sells sandboxes for AI agents, raised a $21 million Series A led by Insight Partners in July 2025. Chip demand is shifting as well. In May 2026, AMD chief executive Lisa Su said agentic AI was raising demand for server CPUs, according to Fortune. Burazin told TNW he expects a CPU shortage bigger than the GPU shortage.
