Former GitHub CEO Thomas Dohmke has raised the largest seed round to date for a development tool launch, according to its lead backer Felicis. Startup Entire has raised $60 million at a $300 million valuation.
Entire offers an open source tool to help developers better manage code written by AI agents.
The entire technology has three components. One is a git-compatible database for consolidating AI-generated code. Git is a version control system popular with enterprises and used by open source sites such as GitHub and GitLab.
Another component is what it calls a “universal semantic reasoning layer” to allow multiple AI agents to work together. The final piece is a native AI user interface designed with agent-human collaboration in mind.
The first product Entire is releasing is an open-source tool it calls Checkpoints that automatically pairs every piece of software an agent submits for use in a software project with the context that created it, including prompts and overrides. The goal is to allow a human developer to check, search, and possibly learn from why the AI did what it did.
It all hopes to help developers better deal with large volumes of software created by AI coding agents. Popular open-source projects are especially inundated these days with proposed code contributions that may or may not be AI, meaning poorly designed and possibly unusable code.
Dohmke explains in a press release: “We’re experiencing an agent boom, and now huge volumes of code are being generated faster than anyone can reasonably comprehend. The truth is that our manual software production system—from issues, to git repositories, to pull requests, to deployment—was never designed for the AI era.”

Dohmke was the CEO of Microsoft’s GitHub for four years and left in August 2025 to found a startup, he said in a post on X at the time. During his time there, he oversaw the rise of the popular coding agent GitHub Copilot.
Other investors in the seed round include Madrona, M12, Basis Set, Harry Stebbings, Jerry Yang and Datadog founder and CEO Olivier Pomel.
