Thomas Dohmke, the former CEO of GitHub, has stepped out with something new. His startup Entire launched in February with a $60 million seed round at a $300 million valuation, making it one of the largest seed rounds ever for a developer tools company.
The pitch? Developer tooling needs to be rebuilt from scratch for a world where AI agents write most of the code.
What’s the problem?
Dohmke’s argument is pretty straightforward: the tools we use to manage software (git, pull requests, CI/CD pipelines) were all designed around the assumption that humans write code. That assumption is rapidly becoming outdated. As he told Axios , “Soon, developers won’t look at the code anymore, as agents will write way more than humans can review.”
It’s a bold claim, but hard to argue with the trajectory. Between Claude Code, Cursor’s Composer, and OpenAI’s Codex models, the shift from human-authored to agent-authored code is accelerating fast.
Enter Checkpoints
Entire’s first product is Checkpoints , an open-source CLI tool that captures the context behind AI-generated code. Think of it as a layer on top of git that records the prompts, reasoning, and decision steps that led an AI agent to write what it wrote. Every commit gets enriched with the “why” behind the code, not just the “what.”
The idea is that as code review shifts from reading diffs to auditing agent behavior, you need a way to trace back through the reasoning. It’s basically provenance tracking for AI-written code.
Who’s backing it?
The seed round was led by Felicis, with Madrona, Microsoft’s M12, and Basis Set also participating. The investor list reads like a who’s who of the developer ecosystem: Gergely Orosz (The Pragmatic Engineer), Theo Browne (T3 Chat), Jerry Yang (AME Cloud Ventures), Olivier Pomel (Datadog CEO), and Garry Tan (Y Combinator).
That’s a lot of very opinionated people placing the same bet.
Why it matters
Dohmke likes to compare this moment to the shift from craft production to the assembly line in manufacturing. Whether that analogy holds up or not, he’s got a point that the current developer workflow wasn’t designed for a world where agents do most of the heavy lifting. Someone was going to try to build the next layer of infrastructure for this, and it’s hard to think of anyone better positioned than the guy who ran GitHub for the past few years.
The real question isn’t whether agent-authored code needs better tooling. It obviously does. The question is whether Entire can move fast enough to define the category before the incumbents catch up.
