Former GitHub CEO Thomas Dohmke has raised the largest seed round ever for a development tools startup, said Felicis, GitHub’s lead backer. Startup Entire has raised $60 million at a $300 million valuation.
Entire provides open source tools that give developers better control over the code written by AI agents.
Entire’s technology has three components. One is a Git-compatible database for integrating AI-generated code. Git is a distributed version control system popular with enterprises and used by open source sites such as GitHub and GitLab.
Another component is what’s called a “universal semantic inference layer,” which aims to allow multiple AI agents to work together. The final part is an AI-native user interface designed with agent-human collaboration in mind.
The first product Entire will release is an open source tool called Checkpoints that automatically combines any software an agent submits for use in a software project with the context in which it was created, such as prompts or transcripts. The idea is to allow human developers to review, find out why the AI acted the way it did, and even learn from it.
Entire wants to help developers better handle large volumes of software created by AI coding agents. Recently, popular open source projects have been particularly overwhelmed by AI failures or otherwise, proposals for code that is poorly designed and potentially unusable.
Dohmke explains in a press release: “We are living in the midst of an agent boom, where massive amounts of code are being generated faster than humans can reasonably comprehend. The truth is, our manual software production systems, from issues to Git repositories to pull requests to deployments, were never designed for the age of AI in the first place.”

Domke served as CEO of Microsoft’s GitHub for four years before leaving in August 2025 to start a startup, he said in a post on X at the time. During that time, he oversaw the rise of popular coding agency GitHub Copilot.
Other investors in the seed round include Madrona, M12, Basis Set, Harry Stebbings, Jerry Yang, and Datadog founder and CEO Olivier Pomel.
