Renaissance Fusion is a stellarator fusion company founded in 2020 in Grenoble, France — the first magnetic confinement fusion startup in continental Europe. The company is developing a simplified stellarator design that integrates laser-engraved high-temperature superconducting (HTS) magnets with liquid metal shields and modular coils to reduce complexity, size, and cost while maintaining the inherent advantages of steady-state, stable operation. By focusing on manufacturability and scalability, Renaissance aims to deliver safe, abundant, zero-carbon baseload power to the grid in the 2030s. Headquartered in Grenoble with a subsidiary in Pisa, Italy, the company has raised over €60M, filed 12 patent families, and grown a diverse team of more than 100 scientists and engineers from 24+ nationalities. Renaissance Fusion is advancing practical stellarator technology for commercial fusion energy.
