$17M Series A: GitButler Builds the Future of Code

GitButler, a version control tool co-founded by GitHub's Scott Chacon, has raised a $17 million Series A led by Andreessen Horowitz, with continued backing from seed investors Fly Ventures and A Capital. The company shared details about the raise and its vision in a post by Chacon himself.

The funding will go toward building what the team describes as infrastructure for how software gets built next. According to the announcement, today's developers are still using a tool, Git, that was originally designed for sending code patches over mailing lists — a workflow that doesn't map well to how teams actually work today, let alone how AI agents operate.

GitButler is the Git-backed change management tool for modern, AI coding workflows. It offers parallel and stacked branches, unlimited undo, agent integrations, and more. It's Git, refined. The tool is built for humans and agents alike, designed to drop into any existing Git project.

In the announcement, Berlin-based Chacon reflects on a key lesson from his time at GitHub: developers don't struggle because they can't write code — they struggle because context breaks down between tools, between teammates, and increasingly between people and AI agents. GitButler wants to fix that.

The company recently released a technical preview of the GitButler CLI, targeting short-lived, trunk-based workflows. A global team headquartered in the US, GitButler has hubs in both San Francisco and Berlin, making it a genuine part of the city's growing tech scene.

The bigger vision? Making coding genuinely social — where your tools help you collaborate in real time, reduce conflict, and keep every agent and human on the same page.
