Omen AI raises $31M to monitor data center cooling liquid

In short: Omen AI raised $31 million to help data centers detect bacteria in chip cooling liquid before it causes costly shutdowns.

What happened

Omen AI, a startup founded in 2024, said it raised a $31 million Series A funding round. The round was led by Nava Ventures, with participation from CRV, Vanderbilt University, Mann+Hummel, Starhill Holdings, Hard Launch Capital, and individual executives from companies including Bridgestone, GM, Johnson Controls, and Tensorwave.

The company’s product is a small spectrometer, a light-based sensor that can “read” what is in a liquid (like checking a drink’s ingredients without tasting it). It is designed to monitor the coolant fluid used in some modern data centers, where high-power computer chips are cooled by liquid instead of air.

As data centers push chips to run hotter, some operators increase the water content in the cooling mix because water carries heat well. But more water can also make it easier for bacteria to grow, which can clog the system. Fixing that often means flushing the system and shutting down a rack of chips for five or six hours, which Omen AI says can be very expensive.

Omen AI says its device can spot early signs of bacterial growth in real time, so operators can act before the problem spreads. The company has worked with Caterpillar dealerships in other industries, and it is now working with about a dozen data center customers, including TensorWave.

Why it matters

Even if you never see a data center, they power the online services many people use every day. Fewer surprise shutdowns can mean more reliable apps and websites, and potentially lower operating costs over time.
