The two-year-old startup is helping 8,000+ companies streamline buggy AI-generated code — and cutting human code review needs in half
Code Review Bottlenecks Create New Opportunity
As AI coding assistants like GitHub Copilot grow more popular, so do their side effects — buggy, incomplete, or “vibe-coded” output. For Harjot Gill, that problem became the foundation of a business: CodeRabbit, an AI-powered code review platform, now valued at $550 million after raising a $60 million Series B.
- CodeRabbit launched in early 2023 and quickly acquired FlexNinja, Gill’s prior startup.
- It’s growing 20% month-over-month and now surpasses $15 million in annual recurring revenue (ARR).
- Over 8,000 companies, including Chegg, Groupon, and Mercury, use CodeRabbit to automate and accelerate code review.
Why Code Review Is More Broken Than Ever
With AI generating code faster than ever, developers are spending more time fixing and reviewing it.
- “AI code output is often buggy or unusable,” said Gill. “That creates bottlenecks in the code review process.”
- CodeRabbit reviews AI-generated and human-written code by understanding the context of a company’s codebase.
- It acts like a “coworker” for engineering teams, catching bugs and suggesting corrections before human review.
Companies using CodeRabbit report cutting manual review labor by up to 50%, helping offset the rising cost of AI inefficiencies.
Backing from Big Names in AI and SaaS
The Series B round was led by Scale Venture Partners, with participation from NVentures (Nvidia’s VC arm), CRV, and other returning investors.
- The new raise brings CodeRabbit’s total funding to $88 million.
- Nvidia’s backing signals the startup’s potential role in AI infrastructure and developer tooling ecosystems.
Gill previously sold his startup Netsil to Nutanix in 2018, bringing credibility and execution experience to CodeRabbit’s fast-paced growth.
Competitive Landscape: Specialized vs. Bundled Solutions
CodeRabbit is not alone in the AI code review race. Its rivals include:
- Graphite, which raised $52M Series B led by Accel
- Greptile, reportedly in talks for a $30M Series A with Benchmark
- Full-stack AI tools like Anthropic’s Claude Code and Cursor, which include code review as one of many features
But Gill argues that focus matters:
“CodeRabbit is a lot more comprehensive in terms of depth and technical breadth than bundled solutions,” he said.
He’s betting that dedicated, context-aware platforms will win out over general-purpose AI assistants.
A New Reality: “Vibe Code” and the Human Cleanup Layer
Even as AI speeds up development, engineers are finding themselves in a new role: AI bug fixer.
- Some companies are hiring engineers specifically to clean up AI-generated code, now jokingly referred to as “vibe code cleanup specialists.”
- Tools like CodeRabbit aim to reduce that burden while maintaining code quality — particularly for teams shipping rapidly or operating at scale.
For now, $30/month per developer is a price many are willing to pay for faster, safer deployments.
