CodeRabbit Secures $60M in Funding at $550M Valuation

Harjot Gill was leading FluxNinja, an observability startup he co-founded several years after Netsil, his first company, was acquired by Nutanix in 2018, when he identified an emerging trend.

"Our remote engineering team began adopting GitHub Copilot for AI code generation," Gill explained to TechCrunch. "As this adoption grew, it became evident that a secondary consequence would be increased bottlenecks in the code review process."

In early 2023, Gill launched CodeRabbit, an AI-driven code review platform, and it subsequently acquired FlexNinja.

Gill's forecast proved accurate: developers now routinely use AI coding assistants, yet the resulting code often contains bugs, requiring significant time for corrections.

CodeRabbit helps identify these errors. According to Gill, the company's monthly growth rate is 20%, and it now generates over $15 million in annual recurring revenue.

Investors are impressed by the startup's rapid expansion. On Tuesday, CodeRabbit disclosed a $60 million Series B funding round, valuing the company at $550 million. This investment, led by Scale Venture Partners with participation from NVentures (Nvidia's venture capital arm) and returning backers like CRV, brings total funding to $88 million.

CodeRabbit assists over 8,000 companies, including Chegg, Groupon, and Mercury, in streamlining the traditionally tedious code review process—a task made more demanding by the proliferation of AI-generated code.

Because CodeRabbit comprehends a company's codebase, it can detect bugs and offer feedback—functioning like a collaborative teammate, Gill noted. He added that organizations using CodeRabbit can reduce their human code-review workforce by 50%.

As in many AI sectors, CodeRabbit faces competition. Rivals include Graphite, which secured a $52 million Series B from Accel this year, and Greptile, reportedly negotiating a $30 million Series A with Benchmark.

While top AI coding tools like Anthropic's Claude Code and Cursor also provide code review features, Gill believes customers will eventually favor a specialized solution. "CodeRabbit offers greater depth and technical breadth compared to integrated alternatives," he stated.

Only time will tell if this strategy succeeds. Currently, however, thousands of developers gladly pay $30 monthly for CodeRabbit's service.

Despite the rising adoption of AI code review tools like CodeRabbit, AI systems still struggle to reliably fix bugs and refine "unusable" AI-written code. This inconsistency has prompted the emergence of a new corporate position: the vibe code cleanup specialist.
