Former GitHub CEO Secures $60M Funding for Revolutionary Development Tool Platform at $300M Valuation

Former GitHub CEO Raises Record Seed Round for Dev Tool Startup

In a groundbreaking move, former GitHub CEO Thomas Dohmke has secured the largest seed funding round ever seen for a development tool startup. The lead investor, Felicis, disclosed that Dohmke’s startup, Entire, has successfully raised $60 million, valuing the company at $300 million.

Entire, the brainchild of Dohmke, offers a cutting-edge open-source tool designed to assist developers in effectively managing code generated by artificial intelligence (AI) agents.

The Innovative Technology Behind Entire

Entire’s technology revolves around three key components. Firstly, it boasts a git-compatible database that serves to consolidate AI-generated code. Git, a renowned distributed version control system widely embraced by enterprises and utilized by prominent open-source platforms like GitHub and GitLab.

Secondly, Entire introduces a unique “universal semantic reasoning layer” aimed at facilitating seamless collaboration among multiple AI agents. Lastly, the platform features an AI-native user interface tailored to foster effective agent-to-human interaction.

Revolutionizing Software Development with Checkpoints

The debut offering from Entire is Checkpoints, an open-source tool that automatically associates every software fragment submitted by an agent for project integration with its originating context, including relevant prompts and transcripts. This innovative approach allows human developers to assess, search, and potentially learn from the AI’s decision-making process.

Entire’s mission is to empower developers in managing the vast quantities of software churned out by AI coding agents. Particularly, open-source projects are inundated with suggested code contributions, some of which may be subpar or even unusable AI-generated code.

Speaking on the matter, Dohmke emphasized, “We are witnessing a surge in AI-generated content, with code being produced at an unprecedented pace. The existing manual software production processes were never designed to accommodate the AI era.”

Dohmke’s Transition from GitHub CEO to Startup Founder

Dohmke, who served as CEO of Microsoft-owned GitHub for four years, departed in August 2025 to embark on his entrepreneurial journey by establishing a startup. Notably, during his tenure at GitHub, he oversaw the ascent of the widely popular coding agent, GitHub Copilot.

The seed round for Entire also attracted investments from prominent entities such as Madrona, M12, Basis Set, Harry Stebbings, Jerry Yang, and Olivier Pomel, the founder and CEO of Datadog.
