The escalating demand for compute power, fueled by artificial intelligence, is compelling data centers to maximize efficiency from their GPU racks. This intense utilization has, however, led to an unexpected challenge: bacterial contamination.
Liquid-cooled chips rely on a specialized fluid, a blend of water and a bacterial inhibitor. To operate chips at higher temperatures for improved performance, data center operators often increase the water content in this mixture, as water is highly effective at heat absorption. However, this adjustment unfortunately fosters bacterial growth, leading to detrimental contamination that obstructs fluid circulation. Remedying this requires flushing the entire system, a process that can halt a rack's operation for five to six hours, potentially incurring costs in the millions of dollars.
Omen AI offers an innovative solution: a compact spectrometer capable of continuously monitoring fluid health. This device identifies bacterial proliferation in real-time, preventing it from escalating into a significant issue. Zach Laberge, CEO and founder, elaborates, “You’re not risking huge amounts of downtime because you have no insight into what’s going on chemically.”
Today, Omen AI announced the successful close of a $31 million Series A funding round. Nava Ventures spearheaded this investment, with additional participation from CRV, Vanderbilt University, Mann+Hummel, Starhill Holdings, and Hard Launch Capital. The round also saw personal contributions from executives representing Bridgestone, GM, Johnson Controls, and Tensorwave.
Laberge's entrepreneurial journey began remarkably early; he established his first company in 2020 at the age of 14. This initial venture secured $3 million to deploy sensors on construction equipment, ultimately leading him to leave high school. His parents, including his mother, a former Minister of Education for Ontario, fully supported his decision to forge his own unique path.
Following the closure of his previous startup, Laberge launched Omen in 2024. The initial vision centered on fluid systems as crucial enablers for intelligent construction machinery, allowing equipment to self-diagnose maintenance needs. The core concept aimed to supersede the laborious process of manual sample extraction and lab analysis with immediate, real-time insights. Beyond detecting bacterial growth, Omen's device is also capable of identifying wear in pumps by detecting traces of copper or chromium, and seal degradation through the presence of silicon.
Caterpillar dealerships initially served as significant customers for Omen's heavy vehicle applications. However, given that Caterpillar is also a prominent provider of gas-powered turbines and generators for on-premises data center power, Omen quickly identified an emerging market opportunity.
“That was kind of the transition,” Laberge recounted to TechCrunch. He noted that approximately six months prior, numerous dealerships began inquiring, “‘Hey, we’re starting to put sensors on our turbines, can you guys do anything on the building side of things?’”
Omen's investigation revealed that these facilities, particularly data centers, contain extensive fluid systems, ranging from HVAC units to chip cooling mechanisms. Recognizing this as a rapidly expanding segment of potential customers, Omen strategically shifted its primary focus towards the data center industry.
Cory Rellas, a partner at Nava Ventures and an Omen board member, commented on Laberge's unique position: “It’s rare to see such a young founder who has the respect of established, large corporations in a space that moves a bit more slowly.” He added, “For Omen in particular, much of our diligence came through our introductions with large customers which quickly validated their approach.”
Since its inception in 2024, Omen has successfully secured $40 million in funding. The company is currently collaborating with approximately a dozen data center clients to refine and expand its product offerings, including TensorWave, a firm developing an AI compute cloud utilizing AMD chips.
Piotr Tomasik, President of TensorWave, emphasized in a statement, “The fluid running through these massive systems is a critical variable that most of the industry is flying blind on.” He further stated, “Omen [sees] the future of infrastructure exactly the way we do, better monitoring to optimally support compute customers.”
Although numerous organizations continue to depend on sending fluid samples to external laboratories for analysis, Omen is not the sole innovator in the field of on-premises analytics. Pyxis, a well-established water-monitoring company, recently introduced its own data center coolant monitoring solution earlier this month.
This advanced monitoring approach has been made possible by recent breakthroughs in both optical technologies and signal processing software. Laberge explained, “Hardware is just cheap enough that it makes sense to play at scale, and then signal processing lets us make more sense out of the noise.”
