Sam is the founder and Chief Executuve Officer of Renaissance fusion.

Renaissance Fusion is a deep-tech start-up based in Grenoble, France, with a bold mission to deliver “abundant, clean energy” via next-generation fusion technologies. Renaissance Fusion Founded in July 2019 (idea stage) and officially incorporated in July 2020, the company has rapidly progressed, securing angel investment in early 2021 and a €15 million seed round in June 2022.

Renaissance Fusion operates at the intersection of high-temperature superconductors (HTS), liquid metals, and advanced fusion reactor design, aiming to overcome long-standing barriers in fusion power by deploying novel physical approaches (e.g., liquid-metal walls, HTS coils).

The organisation emphasises three core values — environmental purpose, speed in execution, and simplicity in design — which reflect its ambition to move from concept to demonstration rapidly. Renaissance Fusion Key technical differentiators include a patented portfolio launched in 2022 (11 patent families filed) covering both liquid metal loops and HTS manufacturing techniques.

The choice of Grenoble is strategic: the region offers strong research infrastructure (fusion labs, superconducting magnet facilities, high-tech ecosystem) which the company leverages for rapid prototyping, testing, and iteration.

By commercialising fusion technologies with novel material and process innovations, Renaissance Fusion aspires to contribute to many of the United Nations’ Sustainable Development Goals (SDGs) and play a foundational role in a carbon-neutral future. It envisions not only energy-generation applications but also adjacent spin-off technologies (for example, superconducting systems or liquid-metal handling) that can accelerate adjacent sectors of the deep-tech economy.

With clear ambitions for industrial scale-up and replication, the company positions itself as a key node in Europe’s strategic technology stack for net-zero and advanced manufacturing.
