Greptile, a San Francisco, CA-based AI code reviewer, raised $25M in Series A funding. The round was led by Benchmark with continued participation from Cory Levy, YC, and Initialized Capital. The company has also launched Greptile 3, a major product update that expands the AI platform’s code review capabilities. Greptile has developed AI that now reviews 500 million lines of code monthly for top software teams, including Brex, Substack, PostHog, Bilt, and Y Combinator’s internal software team. Greptile 3 will be free for students, open-source projects, and nonprofits, making enterprise-grade code review AI accessible to the broader developer community.
