Omen AI has raised $31 million to help develop its systems for monitoring servers and other data center equipment.The San Francisco-based firm has closed its Series A round, which was led by Nava Ventures. It brings the amount of money Omen AI has raised since it was founded in 2024 to $41.5 million.Investors in the round include Meta’s former chief operating officer, Sheryl Sandberg, and Mike Mattacola, chief business officer at neocloud CoreWeave. CRV, Vanderbilt University, LMNT Ventures, Mann+Hummel, Borusan Ventures, Starhill Holdings, Hard Launch Capital, and executives from Bridgestone, GM, Johnson Controls, and TensorWave also participated.Omen AI uses fluid analysis to read the health of equipment such as servers in data centers and other industrial settings. It claims this can help companies know which pieces of kit are about to fail before they fail.Its sensors attach directly to a machine's fluid system (this could be oil, coolant, or water) and deliver analysis of metal content, bio-contaminants, wear patterns, and fluid degradation in real time.Zach Laberge, founder and CEO of Omen AI, said: "I started working with heavy equipment manufacturers as a teenager and watched machines fail because of the antiquated methods the industry uses for monitoring fluid health. Taking a sample, shipping it to a lab, and waiting days for results is dangerously inadequate when you're protecting billions in GPU infrastructure and operating industrial machines."Omen AI was built to prevent catastrophic failure. We help data centers push their hardware to the absolute limit, unlocking compute performance operators didn't know they had, and enabling industrial machine operators to prevent costly failure."Laberge’s company offers two different packages for data centers. It markets permanent sensors that connect directly to the machine's fluid system with a one-time, non-invasive installation. It also offers a portable diagnostic unit that can be used to immediately identify issues.The firm says it already works with data center operators representing $200 billion in assets and between 10GW-14GW of capacity. For these customers, Omen AI monitors coolant health in real time."Whether it's a liquid-cooled AI infrastructure or a fleet of industrial machines, the cost of an unplanned failure is staggering,” said Cory Rellas of Nava Ventures. “Despite the high stakes, these systems are still monitored with lab tests that take days. Omen AI built the solution: continuous, real-time visibility into the health of the machines doing the world's most critical work. Zach and his team aren't just building a better sensor; they're building the nervous system for the machines powering the modern world."
