Former GitHub CEO launches new developer platform with huge $60M seed round

Thomas Dohmke, who helped scale GitHub Copilot during his tenure as CEO at GitHub, is back with a new startup that’s coming out of stealth with a hefty $60 million seed round.

Silicon Valley venture firm Felicis, which led the round, called it the largest seed investment ever for a developer tools startup. Other backers include Seattle-based Madrona, Microsoft’s VC arm M12, and Basis Set, along with individuals such as Yahoo co-founder Jerry Yang, Y Combinator CEO Garry Tan, Datadog CEO Olivier Pomel, and developer community voices such as Gergely Orosz and Theo Browne.

Entire, valued at $300 million, is betting that existing developer tools aren’t built for the rise of AI coding agents. Its platform is designed for teams that increasingly manage fleets of AI coding agents rather than writing every line themselves.

Entire is shipping its first open-source project, a command-line tool called Checkpoints. The software records the reasoning and instructions behind AI-generated code and saves that information together with the code itself, so teams can see how and why changes were made. The goal is to make AI-written software easier to review and audit.

Checkpoints is launching with support for Anthropic’s Claude Code and Google’s Gemini CLI, with plans to add other popular agents over time.

“Just like when automotive companies replaced the traditional, craft-based production system with the moving assembly line, we must now reimagine the software development lifecycle for a world where machines are the primary producers of code,” Dohmke said in a statement. “This is the purpose of Entire: to build the world’s next developer platform, where agents and humans collaborate, learn and ship together.”

Entire enters an increasingly competitive market for AI coding tools, with companies such as Google, OpenAI, Anthropic, Microsoft, Cursor, and others offering their own platforms and services.

Dohmke moved from Germany to the United States after selling his startup HockeyApp to Microsoft in 2015. He took over as GitHub CEO in 2021, several years after its acquisition by Microsoft, and led the unit for nearly four years. Dohmke, who is based in Bellevue, Wash., left in August to work on Entire.

Entire has 15 employees and operates as a fully remote company, with team members who previously built developer tools at GitHub and Atlassian. The startup plans to expand its headcount as it works toward a broader platform launch later this year.
