Greptile raises $50M to audit AI-written code

What's the deal? Greptile has raised a $50 million Series B led by Menlo Ventures, valuing the San Francisco startup at $750 million. Jump TradingDealroom has a profile for this one.

What's the endgame? Greptile sells software that reviews and tests code changes before they merge, acting as an independent check on work from both human developers and AI coding agents. It says it reviews and tests more than 1% of all pull requests opened on GitHub daily, serving teams including Nvidia, Coinbase, and Vanta.

What's the money for? The company plans to expand from code review into automated testing and runtime validation. Its stated mission is to let teams building mission-critical software "auto-merge complex changes."

Why now? AI has made writing code far faster, but chief executive officer Daksh Gupta argues the gains in shipping features have been "modest" because engineers still need to confirm changes work and won't break things. More machine-generated code means more demand for a trusted check before it ships.

What could go wrong? Greptile did not disclose revenue alongside its $750 million valuation, making the figure hard to assess. It also faces a larger rival: CodeRabbit raised $143 million at a $1.5 billion valuation in August as it expanded from review into governing AI-generated code.

The signal: The raise sits in the top 10% of all US enterprise software Series B rounds by size. It reflects growing investor conviction that the surge in AI-written software will need independent safeguards before it reaches production.
