What Kiutra does

Kiutra GmbH is a Munich-based deep tech company founded in 2018 that develops and commercializes helium-3-free cryogenic cooling systems for quantum technology applications. The company's core technology is solid-state magnetic refrigeration based on Adiabatic Demagnetization Refrigeration (ADR) and continuous ADR (cADR), using magnetocaloric materials to reach millikelvin temperatures without the scarce helium-3 isotope — a supply chain bottleneck for the quantum industry where helium-3 is primarily controlled by U.S. government reserves and priced at $1,000–$20,000 per liter. The company claims a technical milestone of sub-30 mK continuous operation, which it describes as a first for ADR technology.

Kiutra's product portfolio comprises four cryostat SKUs — L-Type Rapid (sub-kelvin characterization cryostat with automatic sample loading and reported 6–10x faster turnaround than dilution refrigerators), X-Type (scalable sub-kelvin architecture for quantum chips), S-Type (rack-integrated continuous cooling in a 19-inch form factor), and T-Type Optical (kelvin-range cryostat optimized for trapped-ion chips). The hardware line is complemented by recurring-revenue services: Cryogenics as a Service (CaaS) / Measurement as a Service for centralized characterization, a Characterization Lab for sample submission and system rental, and Quantum Training programs.

The business operates a B2B enterprise sales model, selling cryostats directly to quantum computing companies, research institutions, and (via CaaS) startups and SMEs that lack capital for in-house equipment. Pricing is quote-based and not publicly disclosed. The company has raised over €19.5M cumulatively across early-stage rounds (2019 seed from APEX Ventures and HTGF, 2021 round from TRUMPF Venture and Verve Ventures) and more recently through €6.5M in EIC grants (LEMON Pathfinder September 2024, CRYOFAST Accelerator November 2024) and a €13M equity round in October 2025 co-led by NovaCapital and 55 North. The company employs 51–100 people (stated ~50) and reports global customer reach, anchored in the Munich Quantum Valley ecosystem.

Core offering

Kiutra designs, manufactures and sells compact, helium-3-free cryogenic cooling systems (cryostats) using proprietary magnetic refrigeration technology (Adiabatic Demagnetization Refrigeration and continuous ADR) that reach sub-kelvin and millikelvin temperatures for quantum technology companies and research institutions. The company complements its hardware portfolio with Cryogenics as a Service (CaaS) — renting cryostats and providing professional characterization measurement services at its Munich facility — along with quantum training programs.

Product overview

Kiutra is a Munich-based company offering a portfolio of helium-3-free cryogenic cooling products and services for quantum technologies. The product line centers on four cryostat models—L-Type Rapid (fast characterization), X-Type (scalable architecture), S-Type (rack-integrated continuous cooling), and T-Type Optical (for trapped-ion chips)—all using solid-state magnetic refrigeration via ADR/cADR technology instead of scarce helium-3. These are complemented by Measurement as a Service (Cryogenics as a Service / CaaS) and Quantum Training services. The LEMON project focuses on large-scale magnetic cooling development, while CRYOFAST democratizes access to sub-kelvin temperatures through centralized testing services.
