MuRay raised €7.1 million to develop muon imaging for dense metal parts. The Hamburg startup uses muons to create 3D images inside components such as rocket engines and gas turbines. The total includes a €3.5 million private round and €3.6 million in public funding.
Funding details
First Momentum Ventures led the private round, with Caelora as co-lead. Other investors include Superangel, Nordic Science Investments, Mätch VC, Arcas VC, and Tiny VC. The public funding includes a grant from the EU's Horizon Europe program.
Company origins
MuRay grew out of the DESY particle physics research center in Hamburg. Co-founders Kristjan Põder and Andi Hektor launched the company in 2025. It also has a branch in Tallinn.
How the imaging works
The company generates a controlled muon beam and uses its own detectors and AI software. Muons can pass through more than a meter of steel, while X-rays stop after a few centimeters. Scans reveal material composition and take minutes rather than hours.
MuRay plans to open an imaging service for industrial customers in 2027 using DESY's electron beam in Hamburg. A first full-scale system with a laser-plasma accelerator is due in 2029. The startup also targets about 25 staff by the end of 2027.
