Proxima Fusion, a trailblazer in the fusion energy sector, has successfully raised €20 million in seed funding, marking a significant milestone in its journey. This achievement comes less than a year after the company’s notable €7.5 million pre-seed financing round. The infusion of capital underscores the growing recognition of fusion energy’s potential, particularly in the face of pressing challenges such as climate change and energy security.

Amidst escalating concerns over the climate crisis and the imperative of achieving energy sovereignty, European leaders have recently reaffirmed their commitment to nuclear energy during the EU Nuclear Energy summit. Fusion, distinguished by its superior safety profile compared to conventional nuclear fission, emerges as a highly promising energy source due to its minimal production of radioactive waste.

At the heart of Proxima Fusion’s innovative approach lies its proprietary quasi-isodynamic (QI) stellarator technology, featuring cutting-edge high-temperature superconductors. This groundbreaking design enables the cancellation of toroidal currents, effectively mitigating current-driven instabilities and enhancing the robustness of the fusion process. Leveraging advanced simulations and AI-driven engineering, Proxima has developed its stellarator with the aim of overcoming the longstanding challenge of achieving commercial viability in fusion energy.

While the scientific pursuit of QI-enabled magnetic confinement fusion devices spans over six decades, sustained and commercially viable fusion has remained an elusive goal. In 2022, breakthroughs in stellarator optimization catalyzed significant advancements in the field, providing fertile ground for Proxima’s innovative endeavors. By adopting a holistic approach grounded in engineering expertise and simulation capabilities, the company builds upon these foundational achievements, propelling fusion energy closer to reality.

As the inaugural spinout from the esteemed Max Planck Institute for Plasma Physics, Proxima Fusion stands as a testament to the institute’s commitment to pioneering research in fusion energy. Notably, the Max Planck Institute received substantial public investment amounting to €1.3 billion for its W7-X experiment in Germany, underscoring the significance of collaborative efforts in advancing fusion science.

The newly secured funding will fuel Proxima’s strategic initiatives, including the expansion of its team comprising top-tier engineers and physicists based in Munich. Moreover, the company aims to forge stronger public-private partnerships across Europe, amplifying its impact on the fusion energy landscape. Led by redalpine, the oversubscribed funding round garnered participation from key stakeholders, including the Bavarian government-backed Bayern Kapital, German government-backed DeepTech & Climate Fonds, and the Max Planck Foundation. Notably, existing investors, including Plural, UVC Partners, High-Tech Gründerfonds, Wilbe, and TOMORROW of Visionaries Club, have reaffirmed their confidence in Proxima’s vision by doubling down on their pre-seed investments.


Proxima Fusion’s successful fundraising underscores the growing momentum and investor confidence in fusion energy solutions. As the company advances towards commercial viability with its innovative technology and strategic partnerships, it signals a promising shift towards sustainable and resilient energy sources in the market. Investors and stakeholders are increasingly recognizing the transformative potential of fusion energy, positioning Proxima Fusion as a key player in shaping the future energy landscape.
