Omen AI raises $31 million to keep AI data centers from overheating

Omen is a good example of the unglamorous infrastructure layer that the AI buildout is quietly creating demand for, since a liquid cooling loop failing can force a costly multi hour shutdown that has nothing to do with the chips themselves. Its sensors already watch over data centers representing 200 billion dollars in assets, which suggests operators will pay serious money just to avoid unplanned downtime. It is a reminder that a lot of the money flowing into AI right now goes toward keeping the physical plumbing running, not toward smarter models.
