GitHub CEO Thomas Dohmke will leave at year's end to start a new company, as Microsoft integrates the platform into its Core AI division and reshuffles leadership to align with AI goals.

"GitHub and its leadership team will continue its mission as part of Microsoft’s CoreAI organization, with more details shared soon," Dohmke wrote. "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."

Thomas Dohmke, CEO of GitHub, will step down to launch a new startup as the platform reaches record growth driven by Microsoft's Copilot.
