Who We Are
We are Europe's fastest-growing fusion startup, building the first generation of fusion power plants using quasi-isodynamic (QI) stellarators—the clearest, most robust path to putting fusion on the grid.

Stellarators are the power plants of the future, promising clean, safe, and abundant fusion energy for all.
We're leveraging decades of research in magnetic confinement fusion, combining advances in stellarator optimization, computational design, and high-temperature superconducting (HTS) magnet technology with the expertise behind the record-breaking W7-X stellarator at the Max Planck Institute for Plasma Physics (IPP).

Our Collaboration with the Max Planck Institute for Plasma Physics
Standing on the shoulders of giants
The world’s most advanced stellarator, Wendelstein 7-X (W7-X), was completed in 2015 by the Max Planck Institute for Plasma Physics (IPP) and has since repeatedly broken key performance records.
As the first-ever spin-out from the IPP, Proxima brings together fusion scientists from the Max Planck Society with experts across engineering and computer science.
