Iceotope raises $26M to cool AI's overheating data centres
What's the deal? Iceotope Group, a UK-based provider of precision liquid cooling for data centres and edge infrastructure, has raised $26M in a Series B round. Two Seas Capital and Barclays Climate Ventures led the investment, with participation from existing backers Edinv, ABC Impact, Northern Gritstone, and British Business Bank.
The company builds liquid cooling technology designed to manage the intense heat generated by high-density AI computing hardware.
Why now? AI workloads are pushing data centre power and cooling demands to unprecedented levels. Traditional air cooling struggles to handle the thermal output of modern GPU clusters, making liquid cooling a near-necessity for next-generation infrastructure.
The market timing is sharp: hyperscalers and colocation providers are racing to build out AI-ready capacity, and cooling has emerged as one of the biggest bottlenecks.
What could go wrong? Liquid cooling remains a relatively niche segment competing against deeply entrenched air-cooling infrastructure. Retrofitting existing data centres is costly and complex, and Iceotope faces competition from larger incumbents as well as other startups chasing the same opportunity.
Adoption also depends on data centre operators' willingness to overhaul their thermal management approach — a shift that requires both capital and conviction.
The signal: This round reflects a broader trend: as AI infrastructure scales, the picks-and-shovels companies enabling that build-out are attracting serious investor attention. Cooling, power, and connectivity are becoming as critical — and as fundable — as the AI models themselves. The involvement of a climate-focused investor like Barclays Climate Ventures also highlights how sustainability concerns are shaping infrastructure investment decisions.
