# Microsoft's GitHub CEO Thomas Dohmke To Exit By Year-End For New Startup

GitHub CEO **Thomas Dohmke** announced that he will step down by year-end to launch a new startup venture. The departure comes as GitHub reaches unprecedented scale with over 150 million developers and $2 billion annual revenue run rate.

## Leadership Transition Comes Amid Record Platform Performance

Dohmke, who led GitHub’s integration into **Microsoft Corp.**‘s MSFT CoreAI organization, will remain through 2025’s end to manage the transition. Microsoft has not yet named his successor.

## Copilot Drives Record Financial Performance

GitHub Copilot now represents over 40% of the platform’s revenue growth, according to Microsoft CEO **Satya Nadella**‘s remarks in the July earnings call. The AI coding assistant serves more than 20 million users across 77,000 organizations, marking 180% year-over-year growth.

The platform hosts more than 1 billion repositories and forks, with AI-related projects doubling in the past year alone. GitHub Actions processes 3 billion minutes monthly, up 64% year-over-year.

## Strategic AI Leadership Under Microsoft Ownership

Since Microsoft’s $7.5 billion GitHub acquisition in 2018, Dohmke transformed the platform from a code repository into an AI-powered development environment. GitHub Advanced Security reduced vulnerability remediation time by 60%, while teams now fix security issues 3x faster using AI assistance, according to Dohmke’s post.

The platform achieved multi-model AI integration, partnering with **Anthropic,** **Google** and **OpenAI**. GitHub recently launched Copilot Free for millions of users and introduced synchronous agent modes in Visual Studio Code.

## Market Impact and Future Outlook

GitHub operates as part of Microsoft’s Intelligent Cloud segment, which generated $64.7 billion in revenue in the fourth quarter of 2024, exceeding analyst estimates of $64.36 billion.
