Calyos is proud to announce the successful completion of a €4 million capital raise, backed entirely by its existing shareholders. This investment marks a pivotal step in the company’s strategic roadmap, ensuring the continued advancement of its cutting-edge two-phase cooling technologies across key sectors, including E-Mobility and Computing.
This new funding strengthens Calyos’ financial position and reinforces shareholder confidence in the company’s long-term vision. With this support, Calyos is now firmly on track to reach break-even within the next two years. The investment will enable the company to scale operations, drive commercial momentum, and consolidate its leadership in sustainable two-phase, passive thermal management solutions.
Calyos will leverage the funds to further build on its established presence in the Automotive sector, where demand for innovative, energy-efficient cooling systems continues to rise. As electric vehicle architectures become increasingly complex, Calyos’ passive two-phase cooling technology offers a compelling answer to the thermal challenges of modern power electronics, processors and batteries. Calyos will continue to expand our relationship with strategic Tier 1 partners in order to meet the needs of the OEMs together.
In parallel, Calyos will strategically re-target the Data Center market, which is undergoing a rapid transformation driven by the explosive growth of artificial intelligence. With compute densities climbing and energy efficiency under increasing scrutiny, Calyos is well-positioned to meet emerging cooling demands with solutions that reduce energy consumption, improve reliability, and support sustainability objectives.
“This capital raise reflects the strong belief our shareholders have in Calyos’ mission and market potential,” said Antoine de Ryckel, CEO of Calyos. “It gives us the momentum to continue delivering impactful innovation in thermal management, while expanding our footprint in sectors where performance and sustainability are critical.”
As Calyos enters this new growth phase, the company remains committed to pioneering advanced cooling technologies that support cleaner, more efficient systems across high-impact industries.
