Entire, founded by ex-GitHub CEO Thomas Dohmke, raised a $60M seed at a $300M valuation to build open-source developer tools to better manage AI-written code

Former GitHub CEO Thomas Dohmke has raised the largest-ever seed round for a dev tool startup, according to its lead backer, Felicis.

Context & Ripple Effects

Entire enters a developer-tools market already being reshaped by generative AI: Thomas Dohmke had previously described AI as making developers more efficient and shortening development cycles in a discussion of generative AI's impact on software work.

The company’s focus on managing AI-written code sits alongside earlier funding for AI systems designed to automate codebase-wide migrations and refactoring, shifting attention from code generation alone toward governing changes across a codebase.

First-order effects

Entire has substantial seed capital to build its open-source tooling and pursue its stated goal of managing AI-written code.
The $300M valuation gives Entire an early financing benchmark in developer tooling, while Felicis becomes the lead backer behind Dohmke’s new company.

Second-order effects

Developer-tool vendors pursuing AI-assisted coding, review, refactoring, and codebase automation will face a better-funded entrant focused on the management layer rather than generation alone.
An open-source approach could make adoption and integration a central competitive lever, especially for teams evaluating how AI-produced changes fit into existing repositories and workflows.

Third-order effects

If AI-generated code becomes a larger share of development work, developer platforms may increasingly compete on controls, review, and lifecycle management for machine-produced changes—not only on the ability to generate code.
Large seed rounds for this layer suggest capital is moving beyond standalone coding assistants toward broader AI workspace tooling, though it remains unclear which workflow components will become durable platforms.

The trend: AI developer tooling is broadening from code generation into the governance and operational management of AI-assisted software development.

Here's what GitHub's last CEO @ashtom has been up to: building an agent-first dev platform. I'm an investor. They just shipped Checkpoints. It's open source, easy to use. It adds agent context (eg trajectories, prompts, token usage etc) to PRs. Get it at https://entire.io/

tl;dr Today, we're announcing our new company @EntireHQ to build the next developer platform for agent-human collaboration. Open, scalable, independent, and backed by a $60M seed round. Plus, we are shipping Checkpoints to automatically capture agent context. In the last three
