An in-chip microfluidic cooling company that uses AI for its designs has raised $25 million.

Corintis said that Applied Digital led the investment round, which brought the Swiss-based business’s total funding to $58m. Applied Digital began as a cryptomining company, but has since pivoted to AI and HPC workloads, backed by Macquarie Asset Management.

Instead of traditional cold plate technologies, Corintis is developing a system to push coolant through tiny channels etched into chips, with the AI designs bio-inspired, somewhat akin to the veins on a butterfly’s wing.

In a September research partnership with Microsoft, Corintis said that it removed heat up to three times better than cold plates.

The startup said that the new funds will be used to help expand its US presence with a Washington, DC, office, as well as ramp up its global footprint for manufacturing microfluidic cooling at scale.

The company also claims to have signed multiple new tech giants as customers since its September Series A, when it raised $24m.

“As a category leader in high-performance AI Factories, Applied Digital is further accelerating its leadership position through strategic investments in technologies that will set the industry’s pace and define the future,” said Wes Cummins, chairman and CEO of Applied Digital.

“Our investment in Corintis, together with our investment strategy, ensures that Applied Digital remains at the forefront of data center innovation, from power and cooling to other critical systems that enhance performance, scalability, and efficiency across our campuses.”

Remco van Erp, co-founder and CEO of Corintis, added: “Applied Digital’s investment highlights the critical role of advanced cooling in unlocking the next wave of high-performance computing.

“Optimization of AI infrastructure requires a holistic approach from silicon to infrastructure. Our technology is designed to meet the thermal challenges of today’s most powerful chips and enable the next generation of high-density, energy-efficient computing in a sustainable way by supporting higher coolant temperatures and reducing fresh water consumption.”
