When Google backed Proxima Fusion\u2019s \u20ac411 million round<\/a>, it marked the search giant\u2019s first investment in a European fusion company. But the investors who backed the company say that is not the story. The financing structure behind the money is.<\/p>\n

Proxima Fusion finished the round with a \u20ac2.4 billion valuation, making it Europe\u2019s best-funded fusion company. XTX Ventures and East X Ventures led the investment, while RWE and Google joined as strategic investors, along with KfW Capital<\/a>, SPRIND, Burda Principal Investments, and SKion.<\/p>\n

Previous investors such as Plural<\/a>, UVC Partners, Balderton<\/a>, Cherry Ventures<\/a>, DST Global Partners, Brevan Howard Macro Venture, Lightspeed<\/a>, DTCF, redalpine<\/a>, Leitmotif, Elaia<\/a>, CDP Venture Capital, Bayern Kapital, and the EIC Fund also participated.<\/p>\n

The round caps a period of rapid capital accumulation. In June 2025, Proxima closed a \u20ac130 million Series A<\/a> led by Cherry Ventures and Balderton Capital, and three months later, extended it to \u20ac200 million,<\/a> with CDP Venture Capital joining.\u00a0<\/p>\n

Since spinning out from the Max Planck Institute<\/a> for Plasma Physics in 2023, Proxima has raised over \u20ac650 million, including \u20ac95 million in public grants.<\/p>\n

The mechanism behind the money<\/p>\n

This round was different from a typical growth round as it was set up to unlock public funding. In February, the Free State of Bavaria agreed to provide up to \u20ac400 million in public funding to Proxima, RWE, and the Max Planck Institute for Plasma Physics, but only if Proxima first raised the same amount from private investors.\u00a0<\/p>\n

Proxima met this goal in three months, with the \u20ac411 million round going beyond the target.<\/p>\n

J\u00f6rg Goschin<\/a>, chief executive of KfW Capital<\/a>, the German state development bank, says the structure acts as a bridge over the \u201cvalley of death\u201d between publicly funded research and market-ready growth. He points out that this is different from a subsidy.<\/p>\n

\u201cOur co-investment alongside private lead investors serves as a powerful de-risking signal \u2014 it validates Proxima\u2019s business case and crowds in additional private capital,\u201d Goschin says.<\/p>\n

Cristina Doumitrachko<\/a>, associate at DTCF<\/a>, which invested alongside sister platform HTGF, one of Proxima\u2019s earliest backers, noted that the Bavaria commitment shifted investor focus. <\/p>\n

\u201cThis is no longer a question of whether the project finds backing. It\u2019s a question of execution,\u201d she says.<\/p>\n

Why the venture money followed<\/p>\n

Public support explains the structure. Yet, it does not explain why venture firms without a state mandate returned through five consecutive rounds.<\/p>\n

Benjamin Erhart<\/a>, partner at UVC Partners<\/a> and Proxima board member who co-led its 2023 pre-seed round, said underwriting Proxima required abandoning the firm\u2019s usual risk model.<\/p>\n

\u201cWith Proxima, we had to underwrite scientific and engineering risk against a capital plan measured in hundreds of millions of euros, years before any commercial product existed,\u201d he shares.<\/p>\n

Harald Nieder<\/a>, general partner at redalpine<\/a>, which led the seed round, points to several external validations that have strengthened the firm\u2019s commitment. For example, MIT fusion researcher Dennis Whyte called Proxima\u2019s Stellaris design paper the most important development in fusion technology since the tokamak breakthrough ten years ago.<\/p>\n

\u201cOur conviction continues to deepen at each stage,\u201d Nieder notes.<\/p>\n

Anne-Sophie Carrese<\/a>, managing partner at Elaia<\/a>, which joined the 2025 round, says the team\u2019s execution matters more than theory.<\/p>\n

\u201cWe\u2019ve been very impressed by the execution of the management team since our first investment, that we are standing by our conviction in their vision for the future of energy by continuing to partner with Proxima in this recent fundraising round,\u201d she says.<\/p>\n

Filip Dames<\/a>, founding partner at Cherry Ventures<\/a>, which co-led the Series A and joined this round, links the technical case to government support. He points out that Proxima is building its Alpha demonstrator at a former nuclear fission site in Gundremmingen, using the existing grid connection rather than building new infrastructure.<\/p>\n

\u201cWhen government tailwind and a two-and-a-half-year head start on the technology line up like that, it\u2019s an easy re-up,\u201d Dames concludes.<\/p>\n

CDP Venture Capital, Italy\u2019s state-backed venture arm, adds a similar logic from outside Germany. It joined Proxima at the \u20ac200 million Series A extension and returned for this round. <\/p>\n

Alessandro Scortecci<\/a>, the fund\u2019s Direct Investments Director, tied the investment to industrial access as much as returns: Proxima has committed to opening an R&D centre in Italy, and CDP has already connected the company to Suprema, a portfolio company that makes the high-temperature superconducting tape used in Proxima\u2019s magnets. <\/p>\n

\u201cEnergy costs significantly impact a company\u2019s cost of production, hampering competitiveness and growth\u201d across Italy and Europe\u2019s manufacturing base, Scortecci said, calling commercial fusion \u201cthe most important enabler of the global economic transformation we\u2019re living in.\u201d<\/p>\n

The new money\u2019s read<\/p>\n

Burda Principal Investments, a first-time strategic investor in this round and typically a media and consumer technology firm, sees its involvement as part of a larger plan to support capital-intensive technologies. This includes companies like green steel producer Stegra and sustainable materials firms Planet A Foods<\/a> and Uluu.<\/p>\n

\u201cFor us, this is less an infrastructure play and more a technology breakthrough in the making,\u201d the firm stated, anticipating that larger infrastructure investments will follow once the technology overcomes its remaining challenges.<\/p>\n

Google, RWE, XTX Ventures and East X Ventures did not respond to requests for comment.<\/p>\n

What comes next<\/p>\n

The financing meets Proxima\u2019s current needs, but it raises a question: Will Germany\u2019s approach, which requires state commitment matched by private capital, independent technical milestones, and support from a development bank investing on commercial terms, become a model for others or stay unique?<\/p>\n

Nieder and Doumitrachko both described it this way: It was not a subsidy that made Proxima\u2019s numbers work, but a structure that allowed private investors to take on risks they otherwise could not. \u00a0That question, how Europe turns public research into private capital formation<\/a>, sits at the centre of the continent\u2019s deeptech debate.<\/p>\n

The model still has open variables. Germany\u2019s portion of the Bavaria memorandum depends on roughly \u20ac1.2 billion in federal funding that has not yet been committed. Proxima\u2019s next hardware milestone, which is completing its Stellarator Model Coil in 2027, will test the technical side. Whether Berlin commits the federal portion this year will test the financial side.<\/p>\n

The answer will show whether this is a blueprint for European deep tech or a one-off made possible only by the specific alignment of Bavaria, RWE, and the Max Planck Institute.<\/p>\n","protected":false},"excerpt":{"rendered":"When Google backed Proxima Fusion\u2019s \u20ac411 million round, it marked the search giant\u2019s first investment in a European…\n","protected":false},"author":2,"featured_media":57711,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[8052,151,5,42,8054],"class_list":["post-57710","post","type-post","status-publish","format-standard","has-post-thumbnail","category-germany","tag-deeptech","tag-europe","tag-germany","tag-news","tag-startups"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/posts\/57710","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/comments?post=57710"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/posts\/57710\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/media\/57711"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/media?parent=57710"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/categories?post=57710"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/germany\/wp-json\/wp\/v2\/tags?post=57710"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
