Harjot Gill was running Fluxninja. This is the Observability startup that co-founded several years after selling his first startup Netsil to Nutanix in 2018, and I noticed some strange trends.
“We had a team of remote engineers who are starting to adopt AI code generation at GitHub Copilot,” Gill told TechCrunch. “We saw recruitment happening, but it was very clear that the second order effect would cause a bottleneck in the code review.”
In early 2023, Gill launched Coderabbit, an AI-powered code review platform, and acquired Flexninja.
Gill's predictions have been realized. Developers are currently using AI coding assistants to generate code, but the output is buggy and forces engineers to spend a lot of time fixing it.
Coderabbit helps you catch some errors. According to Gill, the business is up 20% per month and is currently earning more than $15 million in annual revenue (ARR).
Investors find the startup's growth exciting. On Tuesday, Coderabbit announced it had raised a $60 million Series B, valued at $550 million. The round, which brought the startup's total funding to $88 million, was led by scale venture partners with participation from return investors, including Nventures, Nvidia's Venture Capital Arm and CRV.
Coderabbit saves time on famous, frustrating code review tasks, including Chegg, Groupon and Mercury, along with over 8,000 other companies.

Gill said that Coderabbit understands the company's codebase, allowing you to identify bugs, provide feedback, and act like a colleague. He added that companies using Coderabbit can cut the number of people working on code reviews by half.
Like most areas of AI, Coderabbit has a competition. The startup rivals include Graphite, which secured a $52 million Series B led by Accel earlier this year, and Greptile, who reported on a benchmarked $30 million Series A round talk.
While major AI coding assistants like Anthropic's Claude Code and Cursor also offer AI-powered code review capabilities, Gill bets that customers prefer to offer standalone in the long term. “Coderabbit is much more comprehensive in terms of depth and technology width than bundled solutions,” he said.
It is still unclear whether his predictions will be correct. But for now, thousands of developers are clearly pleased to pay Coderabbit $30 a month.
Even with the growing popularity of AI code review tools such as Coderabbit, AI solutions still can't completely trust that fix bugs and “unusable” code written by AI. The reliability of AI-generated code has created a new company role: Vibe Code Cleanup Specialist.
