AI can write code faster than ever. That means someone has to check it.
CodeRabbit, a startup that uses artificial intelligence to review code for mistakes and security flaws, just raised $143 million in fresh funding. The round puts the company's value at $1.5 billion, and it was led by the venture firms Atomico and Smash Capital, with BMW i Ventures and Datadog also chipping in.
Here is the problem AI created for itself. When both experienced developers and total beginners can generate code with a simple prompt, the volume of code being written explodes. And a lot of it has bugs.
CodeRabbit, founded in 2023, built a tool that reads code as it is written and flags problems automatically. Think of it as a spell-checker for programming, except it also catches security holes and suggests fixes. The company says its product reviews code in real time, so developers catch issues before they ever reach the final product.

The demand makes sense. If AI lets more people write code, then more code needs checking. The company's chief executive, Harjot Gill, called the moment a "land grab" for the market. "There is massive pull in the market right now for a product like this," he said.
The numbers show why investors are paying up. Around 17,000 customers already use CodeRabbit, and the platform handles more than 2 million code reviews every week.
Part of the new money will go toward expanding the company's footprint. CodeRabbit plans to double the size of its European team and pursue growth in Asian markets, especially Japan and Singapore. The company is also adding features that detect security weaknesses in code and offer suggested fixes, which matters more as companies worry about cyberattacks.
Nvidia, the chip giant that has become a major backer of AI startups, was already in the cap table before this round. Its presence signals that the big players in AI see code review as a necessary piece of the ecosystem.
With this round, CodeRabbit has raised more than $200 million since it was founded in 2023.
For everyday investors, this is a window into where the AI money is moving. The first wave of AI hype went to the companies building the chips and the models. The next wave is going to the tools that make AI actually usable in daily work.
Code review might not sound glamorous, but it is the kind of boring, necessary task that every company with a software team needs. As AI makes code generation easier, the market for checking that code only grows. That is why a startup founded just three years ago can pull in a nine-figure round at a $1.5 billion price tag.
The catch is that valuations like this come with expectations. CodeRabbit needs to keep growing its customer base and prove it can hold off competitors, including larger tech companies that might build similar tools. For now, the investors backing this round are betting that the land grab Gill described is real - and that CodeRabbit is one of the companies grabbing the most ground.
