Marvel Fusion
🇩🇪 Munich, DE · Founded 2019 · Active
Marvel Fusion is a German company founded in 2019 and based in Munich, with a second site in Fort Collins, Colorado, developing laser-driven inertial fusion. Its approach, which it calls hollow shell fast ignition, fires short, intense pulses from diode-pumped solid-state lasers at nanostructured targets made with semiconductor-industry methods, and it plans to start with deuterium-tritium fuel that does not need cryogenic cooling. With Colorado State University it is building ATLAS, a laser facility in Fort Collins that it says will commission its first laser in 2027. Its power plant concept is being developed with Siemens Energy. The first close of its Series B in September 2024 raised €62.8 million, led by HV Capital.

- Laser ICF, direct drive
- Fuel
- Proton–boron-11
- Role
- Fusion developer
It is the operator of record for ATLAS (Marvel Fusion) (under construction).
Its recorded equity, about $122m, is the 18th largest of the 25 organisations with a priced round here. Not every round is on record, so this is not its total raised.
Terms
- Laser ICF, direct drive
- Laser beams strike the fuel capsule directly. More efficient than indirect drive in principle, but far more sensitive to how evenly the beams are applied.
- Proton–boron-11
- Called aneutronic because the main reaction releases no neutrons, though side reactions and impurities still produce some. Requires at least an order of magnitude more triple product than D-T. A p-¹¹B roadmap that skips D-T is a listed red flag.
Funding
- 2025-03-27Equity round · Series BEUR 50 million extension of the Series B, announced 27 March 2025, with EQT Ventures, Siemens Energy Ventures, the EIC Fund, Tengelmann Ventures and Bayern Kapital named. The company says this brings the round to EUR 113 million; the first close (EUR 62.8 million) is recorded separately, so only the EUR 50 million increment is recorded here. None of the named investors has an organisation record (Siemens Energy Ventures is named, not its parent).≈$54m
- 2024-09Equity round · Series BFirst close of the Series B, EUR 62.8 million, led by HV Capital (no organisation record yet). The EUR 50 million extension of 27 March 2025 is recorded separately as deal:marvel-series-b-extension-2025; the company's "total round to EUR 113 million" is the sum of the two and must never be recorded as its own deal.≈$68m
