Daytona lands $48.3M Series B for AI agent sandbox platform

What's the deal? Daytona, a cloud infrastructure platform that lets AI agents run code and execute tools autonomously in secure, isolated sandbox environments, has raised $48.3 million in a Series B round, according to a recent SEC filing. The filing shows the total offering is for $60 million, with six investors participating in this close.

What's the endgame? The company, founded by Ivan Burazin, Vedran Jukic, and Goran Draganic, builds the infrastructure that keeps autonomous AI agents contained while they perform tasks. That isolation matters as agents increasingly run code without human oversight.

Why now? The round lands as demand grows for tools that let AI agents act safely and independently. Daytona has not yet closed the full offering, leaving roughly $11.7 million still on the table.

The signal: At $48.3 million, the round sits in the upper third of comparable deals — a notable check size for infrastructure aimed squarely at the agentic AI wave. As enterprises move from experimenting with AI to deploying it in production, the plumbing that keeps autonomous systems in check is becoming its own investment category.
