AI coding assistant Cursor has announced its acquisition of Graphite, a startup specializing in AI-powered code review and debugging. While specific terms remain undisclosed, reports from Axios suggest Cursor paid significantly above Graphite's last valuation of $290 million, which was established earlier this year during its $52 million Series B funding round.
This strategic acquisition is poised to significantly enhance the software development lifecycle. AI-generated code often requires extensive debugging, leading engineers to spend considerable time on corrections. While Cursor already offers AI-powered code review via its Bugbot product, Graphite brings a specialized toolset, notably its "stacked pull request" feature. This innovation allows developers to manage multiple interdependent code changes concurrently, bypassing the traditional wait times for individual approvals. The integration of AI-powered code writing with advanced AI code review tools is expected to dramatically accelerate the entire process, from initial drafting to final deployment.
The AI code review market is seeing increased activity, with other notable players including CodeRabbit, which secured a $550 million valuation in September, and Greptile, a smaller competitor that recently announced a $25 million Series A funding round this fall.
Interestingly, Cursor CEO and co-founder Michael Truell had an early connection with Graphite's co-founders, Merrill Lutsky, Greg Foster, and Thomas Reimers. They first met when Truell was a Neo Scholar, a prestigious program for college students run by Neo, Ali Partovi’s early-stage venture firm. Neo later provided seed funding for Graphite, according to PitchBook data. This shared history extends to common investors, with both companies backed by prominent firms like Accel and Andreessen Horowitz.
This acquisition marks another strategic move for Cursor, which was valued at an impressive $29 billion in November and has been actively expanding its portfolio. The company recently acquired Growth by Design, a tech recruiting strategy firm, last month. Prior to that, in July, Cursor absorbed the talent from AI-powered CRM startup Koala, a deal valued at $129 million post-money, according to PitchBook data.
