Kiutra Raises €13 Million to Scale Helium‑3‑Free Cryogenic Cooling for Quantum Technologies
Kiutra, the Munich‑based deep‑tech startup pioneering sustainable cryogenic cooling solutions for quantum technologies, has successfully closed a €13 million funding round to accelerate global expansion and deployment of its helium‑3‑free magnetic cooling systems — a breakthrough alternative to conventional cryogenic technologies that rely on scarce helium isotopes. The new financing brings Kiutra’s total private and public funding to more than €30 million, reflecting strong investor confidence in its mission to bolster quantum supply chain resilience and industrialise next‑generation cooling infrastructure.
The Series A equity round was co‑led by international investors NovaCapital (Italy) and 55 North (Denmark), two firms known for backing deep‑tech ventures with global ambitions. They were joined by High‑Tech Gründerfonds (Germany), one of Europe’s most active early‑stage technology investors, along with participation from Kiutra’s existing backers. This combination of fresh and continuing support underscores belief in the company’s patented magnetic cooling technology and its strategic role in enabling scalable quantum systems.
Founded in 2018 as a spin‑off from the Technical University of Munich, Kiutra has developed magnetic cooling systems that eliminate the need for helium‑3 — a rare and geopolitically sensitive isotope used in traditional cryogenic refrigeration — by instead using solid‑state materials that achieve ultra‑low temperatures through controlled magnetisation cycles. This approach substantially simplifies cryogenics, making it safer, more scalable, and more sustainable for quantum computing and other ultra‑low‑temperature applications.
The company’s proprietary systems are already deployed globally, supporting research institutions, quantum startups, and industrial partners in advancing quantum hardware development and quality assurance. With the quantum ecosystem expanding rapidly worldwide, demand for reliable, efficient cooling solutions has soared — but traditional reliance on helium‑3 has been highlighted as a critical supply chain risk by organisations including NATO and EU initiatives. Kiutra’s technology directly addresses this vulnerability, offering a resilient, industrialised alternative that can support broader adoption of quantum devices.
Dr. Alexander Regnat, CEO and co‑founder of Kiutra, said the latest investment will strengthen the company’s ability to expand its global presence and deliver scalable cooling platforms that are essential for the quantum industry’s growth. The capital is earmarked not only for scaling production and operations but also for developing modular platforms tailored to complex quantum chips and full‑stack quantum computers, positioning Kiutra to serve both research and commercial applications as the technology evolves.
Investor interest in Kiutra’s mission reflects broader momentum in the quantum technology sector. NovaCapital, which co‑led the round, has signalled confidence in Kiutra’s potential to lead in a crucial enabling technology for quantum computing. At the same time, 55 North — a pure‑play quantum fund — described the company’s differentiated product suite as strategically positioned to create value in scaling quantum infrastructure worldwide. Participation by High‑Tech Gründerfonds, a seasoned early‑stage investor with deep roots supporting German and European deep‑tech growth, further reinforces the depth of backing behind Kiutra’s vision.
This latest financing follows previous support that included grant funding from instruments such as the European Innovation Council (EIC) Accelerator, which has helped Kiutra advance early prototype development and enhance its technological foundation. These public‑private funding streams have helped the company transition from R&D‑driven startup to a global industrial scale‑up capable of addressing one of the quantum industry’s most pressing bottlenecks: access to reliable, cost‑effective ultra‑low‑temperature environments.
Kiutra’s magnetic cooling solutions are designed to serve as critical components of the quantum supply chain, enabling not only research laboratories but also commercial users and industrial partners to build, test, and operate quantum systems without the logistical challenges and environmental concerns associated with traditional cryogenics. By focusing on scalability and ease of use, the company aims to democratise access to cryogenic technology, fostering innovation not only in quantum computing but also in sectors where ultra‑low‑temperature capabilities are essential.
As quantum computing and related technologies move from experimental stages toward broader adoption, the demand for robust, scalable infrastructure will only increase. With its €13 million funding extension and over €30 million raised to date, Kiutra stands poised to be a key enabler in this transformation — delivering helium‑3‑free cooling solutions that strengthen supply chains, support global research, and underpin commercial quantum deployments.
