Proxima Fusion is Europe’s leading stellarator company and the first spin-out from the Max Planck Institute for Plasma Physics, developing commercial fusion power plants using the QI-HTS stellarator concept. The company is building Alpha, a net-energy stellarator demonstrator targeted for the early 2030s, and plans a follow-on commercial plant called Stellaris later in the decade. Proxima leads the Alpha project in partnership with the state of Bavaria, the Max Planck Institute for Plasma Physics and industrial partners including RWE, supported by an Alpha Alliance of more than 50 companies. Headquartered in Munich with offices in Zurich and Oxford, Proxima employs around 200 people across engineering, science and operations. Financially, Proxima has secured more than €650 million in funding to date, including about €95 million in public grants, and plans to expand engineering, manufacturing and magnet production capabilities as it advances toward demonstrator completion.

Focused Energy develops laser-based fusion technology and was founded in 2021 as a spin-off of Technical University Darmstadt. Headquartered in Darmstadt, the company also maintains offices in Berlin, Austin, and San Francisco. It positions itself as a world-leading laser fusion company and aims to translate scientific fusion advances into industrial value creation. The company recently raised $240 million in a Series A—the largest fully secured Series A in the fusion industry—to accelerate system development. Focused Energy plans to deploy the capital at the former RWE power plant site in Biblis, Hesse, using the site’s infrastructure and RWE’s expertise to establish a blueprint for industrial laser fusion. Leadership has stated this financing will help the company expand its lead in laser fusion and commit to long-term industrial implementation in Europe.

WeSort.AI develops a patented AI- and X-ray-based platform designed to identify and recover valuable raw materials from mixed waste, including e-waste and batteries. The company highlights that more than 50% of e-waste and batteries are mis-sorted, causing fires at recycling facilities and loss of critical materials like lithium, cobalt, and rare earth elements. Founded in 2022 by Nathanael Laier and Johannes Laier, WeSort.AI intends to expand its technology capabilities and accelerate system deployments using the newly raised capital. With €10 million in funding from impact-focused investors and organizations, the company aims to scale operations and tap into the “urban mine” of recoverable resources. The articles do not report revenue, user, or other operating metrics.
