Former GitHub CEO launches Entire to rival GitHub for AI teams

Thomas Dohmke ran GitHub until earlier this year. Now he’s building a direct competitor to it.

His startup, Entire, launched publicly this week with a platform it describes as a Git forge: a service for hosting code, reviewing changes, and running builds. That’s the core of what GitHub does. The difference is that Entire is built specifically for teams where AI agents are writing code faster than humans can review it.

The Trails Feature

The headline product is called Trails, which replaces the traditional pull request. Instead of expecting a human to read every line of a diff, Trails uses AI agents to score each code change. The idea is that developers can merge with confidence without manually reviewing everything the agent wrote.

Backing and Context

Entire raised a $60 million seed round in February. Backers include Microsoft’s venture arm M12 and Madrona. Microsoft acquired GitHub for $7.5 billion in 2018 and has since folded it into its CoreAI division, which makes M12’s participation in a GitHub rival worth noting.

Entire is not the only company eyeing this space. AI coding company Cursor launched its own code-hosting service, Origin, in August.

The Operator Angle

If your team is running Cursor, Copilot, or any agent that generates pull requests at volume, the bottleneck is no longer writing code. It’s reviewing it. Entire is betting that AI-scored reviews can close that gap. Whether the scoring is reliable enough to trust on production merges is the question worth watching.
