Microsoft absorbs GitHub into CoreAI division as CEO departs

GitHub CEO Thomas Dohmke has resigned after nearly four years in the role, and Microsoft is dissolving GitHub’s independent status by integrating it into its CoreAI engineering team. This marks the end of GitHub’s separate operation since Microsoft’s $7.5 billion acquisition in 2018, signaling a strategic shift toward tighter AI integration across Microsoft’s development platforms.

What you should know: Microsoft is not replacing Dohmke’s CEO position, instead fully absorbing GitHub into its corporate structure.

• Dohmke is leaving to “become a startup founder again” and pursue opportunities outside of Microsoft and GitHub.
• He will remain through the end of 2025 to help guide the transition.
• GitHub will now operate as part of Microsoft’s CoreAI organization rather than as a separate entity.

The big picture: This integration represents Microsoft’s broader strategy to centralize AI development across its platforms under unified leadership.

• CoreAI is a new engineering group led by Jay Parikh, a former Meta executive.
• The team includes Microsoft’s platform and tools division and Dev Div teams, focusing on building AI platforms for both Microsoft and its customers.
• Parikh envisions creating what he calls an “AI agent factory” for enterprises.

What they’re saying: Dohmke emphasized continuity despite the organizational change.

• “GitHub and its leadership team will continue its mission as part of Microsoft’s CoreAI organization, with more details shared soon,” Dohmke said in a memo to GitHub employees.
• “I’m leaving with a deep sense of pride in everything we’ve built as a remote-first organization spread around the world.”

Strategic implications: Parikh’s vision extends beyond traditional software development to AI-powered enterprise solutions.

• “Just like how Bill [Gates] had this idea of Microsoft being a bunch of software developers building a bunch of software, I want our platform, for any enterprise or any organization, to be able to be the thing they turn into their own agent factory,” Parikh explained in an earlier interview.

Competitive landscape: Dohmke’s departure to potentially create new competition adds an intriguing dimension to the AI development space.

• He recently discussed GitHub’s role in the future of software development and competition in the AI coding assistant market.
• His move to startup founding could potentially create new challenges for Microsoft’s AI development efforts.
