Former GitHub chief executive Thomas Dohmke has secured the biggest seed funding round ever recorded for a developer tool company, as confirmed by lead investor Felicis. His new venture, Entire, has obtained $60 million in funding, valuing the startup at $300 million. Entire provides an open source platform aimed at helping developers more effectively handle code generated by AI agents.

The company’s technology consists of three core elements. The first is a git-compatible database designed to consolidate code produced by artificial intelligence. Git is a widely adopted distributed version control system, commonly used in enterprise settings and by open source platforms such as GitHub and GitLab.

Another component is what the company describes as “a universal semantic reasoning layer,” which is intended to enable multiple AI agents to collaborate. The final piece is an AI-native user interface built to facilitate interaction between agents and human developers.

Entire’s initial product is an open-source tool named Checkpoints. This tool automatically links each piece of software submitted by an AI agent for a project with the context behind its creation, including prompts and conversation transcripts. The goal is to allow developers to review, search, and potentially learn from the AI’s decision-making process.

The startup aims to assist developers in managing the growing volume of software created by AI coding assistants. Many popular open-source projects are currently inundated with proposed code contributions, which may vary in quality and could include what is often termed “AI slop”—poorly designed or potentially unusable code.

In a recent statement, Dohmke remarked, “We are living through an agent boom, and now massive volumes of code are being generated faster than any human could reasonably understand. The truth is, our manual system of software production—from issues, to git repositories, to pull requests, to deployment—was never designed for the era of AI in the first place.”

Dohmke served as GitHub’s CEO for four years before departing in August 2025 to launch his own startup, as he announced in a post on X at the time. During his tenure, he oversaw the rise of GitHub Copilot, a widely used AI coding assistant.

Additional investors in this seed round include Madrona, M12, Basis Set, Harry Stebbings, Jerry Yang, and Datadog founder and CEO Olivier Pomel.
