Iceotope raises $26M to tackle AI infrastructure’s thermal and power density bottleneck

The round, one of the largest ever for cooling technologies, was co-led by Two Seas Capital and Barclays Climate Ventures to reinforce interest in climate-smart solutions.

“Securing such high-caliber investors validates both our technology and our market timing,” says Simon Jesenko, CEO and CFO of Iceotope. “We’ve spent years developing a robust, differentiated IP portfolio and products purpose-built for AI infrastructure, and we’re ready to scale at precisely the moment the industry demands more advanced, sustainable cooling technology. The opportunity ahead – both directly with customers and through our partner ecosystem is significant.”

Iceotope has technology that solves the thermal challenges resulting from ever-more naturally power-dense next-generation HPC and AI infrastructure.

The market for liquid-cooled AI accelerators will see a significant increase as traditional cooling methods have its limitations.

Iceotope’s focus on precision liquid cooling aligns with broader industry concerns around power efficiency, sustainability, and operational scalability as hyperscalers, neoclouds, and enterprise AI operators confront rising energy and water constraints. 

The size of the round particularly with backing from climate-focused investors also reflects growing confidence that cooling vendors with differentiated IP and ecosystem partnerships could become essential enablers of the AI infrastructure buildout now underway across cloud, edge, and HPC environments. This trend mirrors broader market dynamics where AI infrastructure success is increasingly tied to overcoming power, density, and efficiency bottlenecks rather than compute alone.
