Proxima Fusion is Europe’s fastest-growing fusion company and the continent’s best-funded fusion player, as well as the first
spin-out from the Max Planck Institute for Plasma Physics (IPP). Backed by over €650M and powered by a growing team across Munich,
Zurich, and Oxford, we are developing the hardware and infrastructure needed to deliver the world’s first commercial stellarator
fusion power plant.
Our concept advances the most mature fusion technology out there, the Wendelstein 7-X stellarator, through two next-generation
machines: Alpha and Stellaris. Our work combines stellarator optimization, advanced computation, machine learning, and
high-temperature superconducting magnets to unlock higher-performance designs that were previously out of reach.
Turning these designs into a functioning fusion power plant requires excellence and ownership across every discipline, from
physics and engineering to software, manufacturing, law, and business functions.
