Cursor Acquires Graphite to Expand AI-Driven Code Review and Debugging

AI coding assistant Cursor has acquired Graphite, an AI startup focused on automated code review and debugging, extending Cursor’s push to cover more of the software development lifecycle with AI. Financial terms were not disclosed, though the acquisition follows Graphite’s recent $52 million Series B and reported $290 million valuation earlier this year.

Founded by Merrill Lutsky, Greg Foster, and Tomas Reimers, Graphite is known for its “stacked pull request” workflow, which allows developers to manage multiple dependent code changes in parallel. The integration strengthens Cursor’s existing AI code-writing and review capabilities, helping teams move faster from draft to production.

Cursor, led by co-founder and CEO Michael Truell, was last valued at $29 billion and has completed multiple acquisitions in recent months as demand for AI-native developer tools accelerates.
