Why it matters
This valuation reflects the growing investor interest in specialized infrastructure required to scale autonomous AI agent workflows.
Daytona Platforms announced on Friday that it had raised a $60 million Series B round at a $1 billion valuation led by FirstMark Growth. The company says it has now raised a total of $91 million.
The New York-based startup has attracted not just FirstMark (which also led its $24 million Series A in February), but a host of well-known angels in this latest round. Daytona says they include Stripe’s Patrick Collison, Shopify’s Tobi Lütke, Perplexity’s Aravind Srinivas, Zoom’s Eric Yuan, Datadog’s Olivier Pomel, Quora’s Adam D’Angelo (who is also an OpenAI board member), and Mercor’s Brendan Foody. It also names Qualcomm Ventures, Samsung Next, and Okta Ventures as participants.
