Proxima Fusion adds €15 million in Series A extension

New institutional backing supports hardware procurement for the company’s stellarator magnet programme.

The extension brings in CDP Venture Capital’s Large Ventures and Corporate Partners I Energy Tech funds, the EIC Fund and Brevan Howard Macro Venture Fund. It follows the initial €130 million Series A close and takes total company funding to €200 million.

Proxima has placed orders for superconducting tape, structural components and an in-house cable manufacturing line. These purchases support its model-coil programme and prototyping of the hardware needed for a demonstration stellarator.
