Greptile's $50M Series B puts a $750M value on its PR review software

Greptile has raised a $50M Series B led by Menlo Ventures, a round that values the code-review startup at $750M, the company said in a post on X.

Greptile's product reviews and tests pull requests — the proposed code changes developers submit before anything merges. According to the company, its software now reviews and tests more than 1% of all PRs opened on GitHub every day, a measure that puts it inside the daily workflow of a meaningful slice of the world's software development.

The company said thousands of engineering teams use Greptile, naming Nvidia, Coinbase, Decagon and Vanta among them. Greptile frames its role for those customers as an "independent and central validation layer" — a check that sits alongside the review tooling and CI systems engineering organizations already run, rather than replacing them. That positioning matters as code review becomes one of the most contested surfaces in developer tooling, with assistants, linters and test-generation products all competing for the moment before a merge.

The valuation is striking relative to headcount. Greptile said it employs fewer than 50 people, describing itself as "a small, talent-dense team of engineers and researchers in a quiet corner of San Francisco." The company used the announcement partly as a recruiting pitch, inviting engineers interested in joining to get in touch.

Greptile linked the funding news to a blog post titled "Series B and The War on Bugs," signaling that bug detection and test coverage remain central to how it pitches the product. The X post had drawn roughly 222,100 views by the platform's count, with replies from users congratulating the team.

The announcement did not say how the new capital will be spent.
