As enterprises troubleshoot their AI systems, governance has emerged as a key challenge. Some are taking a dual approach: One model to handle incoming queries, while a second model keeps the first one from getting into trouble.

That’s the premise of ZeroDrift, a new AI compliance service that announced a $10 million seed round on Tuesday. (Investors include a16z Speedrun, Reign Ventures, PitchDrive Ventures, and U&I Ventures, among others.) The company deals entirely with the second part of the system, sitting between AI models and end users to flag and replace any messages that might present a compliance problem.

It might seem strange to build an AI system to correct other AI systems’ mistakes — but ZeroDrift’s correction system has a few architectural advantages over the models it will be correcting. The system is triggered by conventional programs that deterministically apply known compliance standards like SOC 2 or GDPR. The LLM only comes in once a message has been flagged, rewriting a compliant version of the same message.

“We’re able to identify deterministically, what are all the regulated areas, what’s the violation that’s being broken, and then we have LLMs that can do the rewrites,” Aroomoogan says.

Critically, the whole system can be run with less latency and more reliability than a conventional LLM. It’s the company’s primary advantage over big labs like OpenAI and Anthropic, which are often already present in the underlying system.

The most obvious use case is for AI chatbots, which are already deployed in front of consumers where there can be serious consequences for rogue answers. But Aroomoogan sees the total addressable market as much larger, potentially spanning AI-generated messages that human beings never see, generated only within automated systems. So far, it’s a relatively small market — but it’s one that will grow as AI proliferates.

If the fundraise is any indication, there’s a lot of pent-up demand for that product. “It was probably the fastest fundraising I’ve done in my life,” CEO Kumesh Aroomoogan says, crediting Andressen Horowitz’s help structuring the seed round. “We closed within three weeks, and we will be oversubscribed by 3x on the amount.”
