GitHub Chief Executive Thomas Dohmke said on Monday he will leave the Microsoft-owned code-hosting platform to launch a new startup, capping a tenure that included a major push into artificial intelligence through the company's Copilot products.

Microsoft will bring GitHub into its CoreAI division with the announcement this morning that GitHub CEO Thomas Dohmke will be stepping down as the leader of the widely used software development platform and code repository.

The move comes as GitHub is facing growing competition from companies like Google and Cursor over AI tools for programmers.
