Iceotope Group, a liquid cooling technology company, has raised $26 million in a Series B funding round led by Two Seas Capital and Barclays Climate Ventures.
The round also included participation from Edinv, ABC Impact, Northern Gritstone, and the British Business Bank. Founded in 2005, Iceotope develops precision liquid cooling systems designed for AI data centres, high-performance computing infrastructure, and edge computing environments.
What The Company Does
Iceotope develops liquid cooling technology aimed at improving thermal management for high-density computing environments.
Its precision liquid cooling systems replace traditional air-cooling approaches with chassis-level liquid thermal management designed to handle the growing power demands of AI infrastructure and high-performance computing systems.
The company’s technology is intended to improve energy efficiency while reducing both electricity and water consumption associated with large-scale computing operations. Iceotope’s systems are designed for deployment across data centres, enterprise infrastructure, and edge computing environments where heat generation is becoming increasingly difficult to manage through conventional cooling methods.
The company has developed a substantial intellectual property portfolio around liquid thermal management and currently holds more than 200 patents related to its cooling technologies.

Market Context / Industry Background
Rapid expansion in AI computing infrastructure is placing increasing pressure on traditional data centre cooling systems.
As AI workloads become more computationally intensive, rack power densities are projected to rise significantly, with some industry forecasts expecting deployments approaching or exceeding 1MW per rack in future AI environments. This shift is challenging the practical limits of conventional air-cooling systems and increasing adoption of liquid-based thermal management technologies.
The growing use of AI accelerators and high-performance computing infrastructure has also intensified demand for more energy-efficient cooling solutions as operators seek to manage rising operational costs and sustainability requirements.
Industry analysts, including SemiAnalysis, have projected substantial growth in liquid-cooled AI infrastructure capacity over the coming years, driven largely by hyperscale data centre operators and enterprise AI deployments.
Iceotope positions itself within this transition toward liquid-based thermal management infrastructure for next-generation computing environments.
Against this backdrop, companies like Iceotope are developing advanced liquid cooling architectures designed to improve energy efficiency, reduce thermal constraints in dense AI clusters, and support the scalability of next-generation data centres as power requirements continue to increase.
This shift is also reshaping competitive dynamics across the data centre ecosystem, encouraging closer collaboration between hardware manufacturers, infrastructure providers, and cloud operators to ensure thermal performance keeps pace with rapidly evolving AI compute demands and energy efficiency targets.
Founder / Investor Commentary
CEO and CFO Simon Jesenko stated that Iceotope has spent years building a differentiated intellectual property portfolio and developing products specifically designed for AI infrastructure requirements.
According to Jesenko, the company is now focused on scaling its technology and commercial operations alongside increasing demand for advanced and more sustainable cooling systems.
The investor group backing the company also reflects growing interest in infrastructure technologies addressing energy efficiency and operational challenges associated with AI expansion.
Growth Plans / Use Of Funds
The newly raised funding will be used to accelerate product and engineering development, expand Iceotope’s patent portfolio, and strengthen partnerships across the broader infrastructure ecosystem.
The company also plans to scale commercial deployment of its cooling technologies across AI data centres, high-performance computing environments, and edge infrastructure markets.
Additional investment will support continued development of thermal management systems designed for increasingly dense AI compute deployments.
