CodeRabbit raises $60M, valuing the 2-year-old AI code review startup at $550M (techcrunch.com)

CodeRabbit, a two-year-old startup that builds AI-powered code review tools, announced a $60 million Series B at a $550 million valuation (bringing total funding to $88M). Founded by Harjot Gill in early 2023 after he folded his observability startup FlexNinja into the project, CodeRabbit says it’s grown ~20% month-over-month and now exceeds $15M ARR, serving customers like Chegg, Groupon and Mercury and more than 8,000 individual developers. The round was led by Scale Venture Partners with participation from Nvidia’s NVentures and returning investor CRV. Technically, CodeRabbit ingests and understands a company’s codebase to flag bugs, suggest fixes, and surface review feedback—claiming it can halve the human effort required for code review. The product targets a rising bottleneck: widespread use of AI coding assistants (Copilot, Claude Code, etc.) produces buggy output that still needs human validation. CodeRabbit positions itself as a deeper, standalone review layer versus bundled offerings from AI IDE assistants; rivals include Graphite and Greptile. Important caveat: despite improvements, AI review tools aren’t fully trustworthy yet, so human oversight (and even new “code cleanup” roles) remains necessary as these systems mature.
