The relentless push for more powerful AI has hit a thermal wall. As chips from companies like Nvidia get exponentially more powerful, they’re also getting dangerously hot, creating a critical bottleneck for the entire industry. Now, Swiss startup Corintis is emerging from stealth with a $24 million Series A and a major partnership with Microsoft to prove its solution: smarter, AI-designed chip cooling.
The funding round, led by BlueYard Capital, brings Corintis’s total to $33.4 million and adds some serious industry muscle to its board, including Intel CEO Lip-Bu Tan. The company isn’t just building better fans; it’s fundamentally rethinking how heat is managed at the silicon level with microfluidic cooling.
Instead of generic blocks of copper, Corintis uses AI and advanced simulation software to design intricate, micro-scale liquid channels that are custom-fit to a chip’s unique thermal landscape. As CEO Remco van Erp puts it, their tech guides coolant "to the most critical regions," much like a natural circulatory system.
A Breakthrough with Microsoft
The real validation for Corintis’s approach comes from its collaboration with Microsoft. The two companies recently announced a breakthrough, developing an in-chip microfluidic system that cooled a server three times more effectively than the most advanced conventional technology.
This isn't just about preventing meltdowns. According to Microsoft, this massive thermal improvement unlocks more performance, greater overclocking potential, and enables new 3D chip architectures that were previously impossible because of heat buildup. By making cooling a core part of the chip design process, not an afterthought, Corintis is positioning itself as a key enabler for the next wave of AI hardware.

With plans to scale its manufacturing to over a million units annually by 2026, Corintis is moving from a research project to a high-volume supplier ready to tackle the heat problem head-on. For an AI industry defined by its insatiable demand for computation, this kind of advanced chip cooling isn't just a nice-to-have; it's becoming a necessity.
