Thomas Dohmke - CEO of Microsoft’s GitHub

Thomas Dohmke, the CEO of Microsoft’s GitHub, has decided to step down. Dohmke held the CEO role for nearly four years. Dohmke will step down from his role by the end of 2025 to pursue his next chapter as a startup founder.

“I am stepping down as GitHub CEO to build my next adventure. GitHub is thriving and has a bright future ahead. The following is the internal post I sent to GitHub employees (Hubbers) this morning announcing my departure”, he stated in a post.

"My startup roots have begun tugging on me and I’ve decided to leave GitHub to become a founder again. GitHub and its leadership team will continue its mission as part of Microsoft’s CoreAI organization, with more details shared soon. I’ll be staying through the end of 2025 to help guide the transition and am leaving with a deep sense of pride in everything we’ve built as a remote-first organization spread around the world", he added.

“After nearly four years as CEO, I’m leaving GitHub to become a startup founder again. With more than 1B repos and forks, 150M+ developers, and Copilot continuing to lead the most thriving market in AI with 20M users and counting, GitHub has never been stronger than it is today. Thank you to Satya Nadella, Julia Liuson, so many countless people, and most importantly, thank you to all Hubbers for the ride of a lifetime”, the LinkedIn post read.

In just the last year, GitHub Copilot became the first multi-model solution at Microsoft, in partnership with Anthropic, Google, and OpenAI and enabled Copilot Free for millions and introduced the synchronous agent mode in VS Code as well as the asynchronous coding agent native to GitHub.
