Omen AI raises $31M for coolant monitoring sensors
Omen AI developed a compact spectrometer to monitor liquid coolant chemistry in real time for liquid‑cooled GPU racks, detecting bacterial growth and signs of component wear to avoid costly shutdowns. The startup, founded by Zach Laberge in 2024, is pivoting from heavy‑vehicle fluid sensors toward data centers and is already working with about a dozen data‑center customers, including TensorWave. Omen announced a $31 million Series A led by Nava Ventures with participation from CRV, Vanderbilt University, Mann+Hummel, Starhill Holdings, Hard Launch Capital and personal investments from executives at Bridgestone, GM and Johnson Controls. The company has raised roughly $40 million to date. The article notes competing on‑premises approaches such as Pyxis’s recent coolant monitoring product and credits recent improvements in optical hardware and signal‑processing software for enabling the approach.
Series A funding for a startup building realtime coolant‑monitoring hardware for AI data centers could improve compute reliability but is a niche infrastructure development with limited immediate impact on the broader advertising ecosystem.

Niv-AI Launches to Optimize GPU Power in Data Centers
Niv-AI, a Tel Aviv-based startup, exited stealth with $12 million in seed funding to measure and manage GPU power usage in data centers. Founded last year by CEO Tomer Timor and CTO Edward Kizis, the company is deploying rack-level sensors that capture millisecond-scale GPU power profiles and plans to build AI models to predict and synchronize power loads — a “copilot” for data center engineers. Backers include Glilot Capital, Grove Ventures, Arc VC, Encoded VC, Leap Forward and Aurora. Niv-AI expects operational deployments in a handful of U.S. data centers within six to eight months and positions its product as an intelligence layer between data centers and the electrical grid.
InsightFinder Raises $15M for AI Observability
InsightFinder AI, an observability startup founded by Helen Gu, raised $15 million in a Series B round led by Yu Galaxy to expand its AI agent reliability products. The company, which has applied machine learning to infrastructure monitoring since 2016, launched a new offering called Autonomous Reliability Insights that combines unsupervised ML, proprietary large and small language models, predictive AI and causal inference to detect, diagnose, remediate and prevent AI model and infrastructure issues. InsightFinder counts enterprise customers including UBS, NBCUniversal, Lenovo, Dell, Google Cloud and Comcast. The company says revenue grew more than threefold in the past year, has under 30 employees, has now raised $35 million total and will use the new capital to hire its first sales and marketing staff and scale go-to-market efforts. InsightFinder positions itself against incumbents such as Grafana Labs, Datadog, Dynatrace, New Relic, Fiddler and BigPanda.
Anemo Labs Raises £700K for AI E-Nose
London-based deeptech startup Anemo Labs has raised £700,000 in pre-seed funding to develop an electronic nose (e-nose) that combines sensor hardware with AI to detect volatile organic compounds (VOCs). The round was led by Zinc and SFC Capital with support from Innovate UK. Founded in 2025 by Koye Sodipo, the company initially targets healthcare applications, analyzing VOCs from urine for non-invasive disease screening. Anemo's in-house sampling platform can collect and label up to 5,000 smells daily, and early tests using the Sniffin' Sticks protocol achieved 84.15% accuracy across 12 scent categories. The funding will advance sensor chemistry, expand data collection, and support clinical validation.
