Omen AI, a startup based in San Francisco, California, has raised a $31 million Series A led by Nava Ventures. The round, announced on June 30, 2026, brings the company’s total funding to $41.5 million since it was founded in 2024.

The company makes a compact spectrometer that tracks the health of the fluid running through liquid-cooled AI data centers. By reading that coolant in real time, the device is designed to catch bacterial growth early, before it turns into a costly failure.

Omen AI is already working with about a dozen data center customers as it builds out the product, among them TensorWave, which is assembling an AI compute cloud on AMD chips.

The round drew a wide mix of investors, including CRV, Vanderbilt University, Mann+Hummel, Starhill Holdings, and Hard Launch Capital, along with personal investments from executives at Bridgestone, GM, Johnson Controls, and TensorWave, as well as Sheryl Sandberg.
