CodeRabbit raised $143 million in a Series C co-led by Atomico and Smash Capital, valuing the AI code-review company at $1.5 billion, Reuters reports via Yahoo Finance. The startup is pairing the cash with Agentic Change Management tools that triage pull requests, explain architectural impact, and keep scanning shipped code as vibe coding floods teams with machine-written changes. Investors are betting governance layers will grow alongside generation tools. The caveat is that review products still must cut merge risk without becoming another bottleneck.
