Anysphere, the company behind the AI coding assistant Cursor, has announced that it has acquired Graphite, a startup that uses AI to review and debug code.
Although terms of the deal were not disclosed, Axios reported that Cursor paid Graphite’s latest valuation of $290 million, which was set when the five-year-old company raised a $52 million Series B earlier this year.
The tie-up makes strategic sense. The output of AI-generated code is often buggy, forcing engineers to spend a lot of time on fixes. Although Cursor offers AI-based code review through it BugboT product, Graphite’s specialized toolset provides a unique feature called “stack pull request”. which allows developers to work on multiple dependent changes simultaneously without waiting for approvals.
Combining AI-powered code writing with AI-powered code review tools speeds up the process from writing code to shipping it.
Other startups providing AI code review include CodeRabbit, valued at $550 million in September, and a smaller competitor, Greptile, which announced a $25 million Series A this fall.
Michael Truell, co-founder and CEO of Anysphere, first met Graphite co-founders Merrill Lutsky, Greg Foster and Thomas Reimers before launching Cursor as Neo Scholar, a prestigious program for college students run by Neo, Ali Partovi’s early-stage venture company. Neo backed Graphite at the seed stage, according to PitchBook data.
In addition, both Cursor and Graphite have other joint investors, including Accel and Andreessen Horowitz.
