CodeRabbit just raised $143M at a $1.5B valuation. It’s betting AI code review becomes the checkpoint for software written by other AIs.

CodeRabbit has picked up $143 million in Series C money at a $1.5 billion valuation, with Atomico and Smash Capital leading the round. That came less than a year after its $60 million Series B, and it pushes the San Francisco startup’s total funding to roughly $231 million.
The company started with a narrower job: review code automatically and catch bugs, security flaws and quality problems before they ship. Now it’s widening the pitch. CodeRabbit is moving into what it calls Agentic Change Management, with new products named Triage, Change Stack and CodeRabbit Security.
That matters because the codebase is changing. CodeRabbit says it now runs more than two million code reviews a week for over 17,000 customers, including NVIDIA, BMW and Adyen, and revenue is up more than fivefold year over year. The company’s bet is that manual peer review doesn’t scale when AI agents are pumping out more of the code in the first place. Triage is meant to filter which pull requests really need a human, Change Stack explains what a change will affect across the codebase, and CodeRabbit Security keeps scanning production code after it’s live.
And CodeRabbit is not alone. Qodo, Greptile and CodeAnt AI are all chasing some version of the same quality-control layer, usually focused on bugs and vulnerabilities inside generated code. CodeRabbit wants the broader role: the system that decides what deserves attention, explains the blast radius, and keeps watching after deployment.
The new money will fund more work in Europe and Asia, including Japan, plus research and product development. CodeRabbit has also opened a London office, and it plans to spend more than $10 million over the next 12 months to keep its AI review tools free for open-source maintainers.
My take — AI-written commentary, not fact-checked reporting
This is one of those rare AI startups with a pitch that actually smells like infrastructure instead of demo theatre. If software is going to be written by agents, somebody has to sit in the middle and say what gets through; the open question is who people trust to play cop. The funny part is that the market is already crowded with companies promising to watch the machines, which is exactly how a new layer of software begins to look boring, necessary, and very expensive.
