Greptile, founded in 2023 and based in San Francisco, develops AI agents that autonomously validate, test, and QA code changes before they are merged. The company has raised $30 million in funding to pursue its mission of transforming how software teams maintain code quality at scale.
Its flagship product is an AI code review agent that automatically reviews every pull request with a complete understanding of the codebase. Unlike traditional linters that check files in isolation, Greptile's system constructs a graph index of entire repositories to understand how changes affect the whole system. The platform now reviews over one billion lines of code every month and serves more than 9,000 engineering teams.
The company operates with a small, talent-dense team working across technical domains including AI agents, codebase understanding, and graph indexing. Its core focus on software engineering and code development positions it at the intersection of artificial intelligence and developer tooling.
