Omen AI Raises $31M Series A to Monitor AI Data Center Coolant

Omen AI has closed a $31 million Series A funding round to expand its coolant monitoring technology for AI data centers. The company develops a miniature spectrometer that sits in liquid-cooled chip loops and continuously analyzes fluid health, tracking bacterial growth, metal particles from component wear, and signs of seal degradation. The Series A financing was announced on June 29, 2026 and is aimed at scaling deployments across more data center operators and AI compute providers.

The round was led by Nava Ventures, with participation from CRV, Vanderbilt University, Mann+Hummel, Starhill Holdings, and Hard Launch Capital, alongside personal investments from executives at Bridgestone, GM, Johnson Controls, and TensorWave. This new capital follows earlier seed funding and brings Omen AI’s post-money valuation to approximately $155 million. The company, founded in 2024, is already working with around a dozen data center customers, including AMD-based AI cloud provider TensorWave, positioning itself as a specialized infrastructure player focused on reliability and uptime in increasingly liquid-cooled AI environments.
