Graphite
Graphite is the AI code review platform where teams ship higher quality code, faster. The company aims to reimagine the future of software development by creating one integrated platform where humans and agents create, review, and merge code changes collaboratively.
Founding Story
The three founders (Merrill Lutsky, Greg Foster, and Tomas Reimers) met in January 2020 at Neo Startup Camp, a workspace and retreat held at the Costanoa resort on the California coast. Shortly after, they founded the company as Screenplay with a mission centered on software code quality. They initially started as a mobile QA and release management tool company. After building an internal code review tool and seeing strong organic adoption (40 users when they expected 20), they pivoted in September 2021 to focus exclusively on code review tools, which became Graphite.
