Recently, a startup called CodeRabbit has attracted widespread attention. Its AI-based code review platform has rapidly risen within just two years. The founder of the company, Harjot Gill, sold his startup Netsil to Nutanix in 2018, and then founded the observability platform FluxNinja. During his time at FluxNinja, he observed an interesting trend: more and more developers began using AI code generation tools like GitHub Copilot, but this led to bottlenecks in the code review process.
Gill founded CodeRabbit in 2023 and acquired FluxNinja. His intuition was correct, as developers now frequently use AI-generated code, but often the generated code contains bugs, requiring engineers to spend a lot of time fixing them. The emergence of CodeRabbit is aimed at addressing this challenge, as it can effectively identify errors in code and provide feedback, helping developers save time.
In the recently concluded funding round, CodeRabbit announced a successful $60 million Series B funding round, with a valuation reaching $550 million. This round was led by Scale Venture Partners, with participation from Nvidia's venture capital division NVentures and existing shareholders CRV. This brings CodeRabbit's total funding since its inception to $88 million.
Today, CodeRabbit has helped companies such as Chegg, Groupon, Mercury, and over 8,000 other companies improve the efficiency of code reviews. Gill stated that by using CodeRabbit, companies can reduce the human resources needed for code reviews by half. His goal is to provide developers with a more comprehensive and in-depth code review solution.
Although CodeRabbit has performed well in the market, it is not without competitors. For example, Graphite recently secured $52 million in a Series B funding round, while Greptile is in talks for a $30 million Series A round with Benchmark. In addition, well-known AI coding assistants such as Anthropic's Claude Code and Cursor also offer AI code review features. Gill believes that despite the variety of options available, customers will prefer independent products like CodeRabbit.
Although AI code review tools are rapidly gaining popularity, there are still trust issues, especially when dealing with "unusable" code generated by AI. Therefore, a new job title, "code cleanup expert," has emerged, specifically responsible for fixing bugs generated by AI.
