Corintis secures additional USD 25 million to scale advanced chip cooling technology

Lausanne-based Corintis has raised an additional USD 25 million in Series A1 funding to accelerate the global deployment of its microfluidic chip-cooling solutions.

Corintis, a deeptech start-up specializing in advanced liquid cooling for high-performance chips, has secured a further USD 25 million in Series A1 financing, following its USD 24 million Series A round earlier this year. The new investment is led by Applied Digital and brings the company’s total funding to USD 58 million, reflecting growing demand for solutions that address the thermal constraints of AI-driven computing.

As AI workloads push power densities to unprecedented levels, liquid cooling is rapidly becoming a prerequisite for next-generation GPU-based data centers. Corintis is positioning itself at the forefront of this transition with direct-to-chip microfluidic cooling systems that can be deployed either as drop-in replacements for standard cold plates or integrated directly into GPUs. The company’s generative design and manufacturing platform enables cooling architectures to be precisely tailored to individual chips, improving thermal performance while remaining cost-effective at scale.

Corintis’ technology has already demonstrated up to three times lower chip temperatures compared to conventional liquid cooling approaches, a performance benchmark validated earlier this year in collaboration with Microsoft. Beyond thermal gains, the approach supports higher power densities, improved energy efficiency and reduced environmental impact, key considerations as hyperscale operators expand AI infrastructure worldwide.

Building the infrastructure powering the AI era

The Series A1 funding will support Corintis’ global expansion strategy, including the opening of a U.S. office in Washington, scaling manufacturing capacity for microfluidic cooling systems, and accelerating customer deployments with major technology and data center operators. The company reports that it has already signed multiple new global technology customers since announcing its initial Series A.

Applied Digital’s participation underscores the strategic importance of advanced cooling within the broader digital infrastructure ecosystem. The data center operator designs and operates high-performance facilities optimized for AI, cloud and advanced compute workloads, and sees Corintis’ technology as a critical enabler of efficiency, reliability and sustainability at scale.

Founded in Lausanne as an EPFL spin-off, Corintis exemplifies the strength of Western Switzerland’s deeptech ecosystem at the intersection of semiconductors, energy efficiency and AI. With this latest financing, the company is accelerating its transition from pilot deployments to large-scale commercialization, reinforcing the region’s position in the global race to build the infrastructure powering the AI era.
