FirstMark partner Matt Turck said the firm also led Daytona's Series A earlier in 2026. In a quote-post of Burazin's announcement, Turck called the new investment a chance to "double down" on the company.

Fortune describes Daytona's product as cloud-based virtual machines, or sandboxes, for AI agents. The company was founded in 2023 by Burazin, Goran Draganić and Vedran Jukić, the outlet reports. Burazin describes his ambition as building Daytona into an "Agent Cloud."

Burazin said key existing investors and angels were doubling down. He told Fortune that about $50 million of the $60 million round came from existing investors; the outlet put Daytona's total funding at about $91 million. Burazin told Fortune he plans to spend most of the new money on sales hires, along with some engineers.

@ivanburazinWe just raised a $60M Series B at a $1B valuation to build @daytonaio into the Agent Cloud. @FirstMarkCap led the round, with all key existing investors and angels doubling down. We're also thrilled to welcome the founders of some generational companies aboard, including @patrickc (Stripe), @tobi (Shopify), @AravSrinivas (Perplexity), @BrendanFoody (Mercor), @oliveur (Datadog), @adamdangelo (Quora) and @ericsyuan (Zoom) We're a 35-person team. But that's about to change; we're hiring across the board, and we'd love for you to join us.2h

@mattshumer_I invested in Daytona about a year ago. The vision is huge. The growth rate is just nutty. And it doesn’t look like it’s going to slow down anytime soon. @ivanburazin is a generational founder. Honestly, with how fast they’re growing, the $1B val is a bargain by now.1h

@amankabeerBeyond honored that @ivanburazin & @JukicVedran allowed us to double down and lead @daytonaio's Series B from the inside It's difficult to put into words how well this team has executed to achieve the ridiculous growth we've seen over the past year, & even more difficult to encapsulate the standard of customer care (& love) they've maintained at that scale Agents will increasingly need their own sets of primitives & services, beyond just compute, in the coming decade. The Daytona Agent Cloud will be the place they come to find them 🚀🚀🚀1h
