AI Code Review Startup CodeRabbit Secures $143M in Funding at $1.5B Valuation

CodeRabbit, an AI-powered code review platform, has raised $143 million in a funding round valuing the company at $1.5 billion. The round was co-led by Atomico and Smash Capital, with new investors including BMW i Ventures, Datadog, and Hirtle Callaghan also participating.

The investment reflects growing investor confidence that widespread adoption of AI coding tools and vibe coding will drive increased demand for software monitoring, as companies contend with a surge in AI-generated code requiring oversight. CodeRabbit’s platform helps developers assess code quality, understand the impact of individual changes, and monitor production systems for vulnerabilities and long-term maintainability issues.

The round comes less than a year after CodeRabbit’s $60 million Series B raise. Luca Eisenstecken, a partner at Atomico, will join the company’s board. Eisenstecken said that as AI becomes foundational to the global economy, organizations will increasingly require independent governance systems capable of validating software regardless of which AI model generated it.

CodeRabbit, headquartered in San Francisco, recently opened an office in London and plans further expansion into Europe, Japan, and other Asian markets. The company said it performs more than 2 million code reviews weekly and serves more than 17,000 customers, including Nvidia, BMW, JFrog, Trivago, Adyen, and Indeed. CodeRabbit also plans to invest more than $10 million over the next year to keep its AI review tools free for open-source projects and maintainers.
