What Marvel Fusion does

Marvel Fusion GmbH is a Munich-based, privately held fusion energy company founded in 2019 that develops laser-driven inertial fusion energy (IFE) technology. Its core technical concept combines a proprietary fast ignitor architecture with novel interactions between ultra-short, high-contrast laser pulses and small-scale nanostructures, building on the inertial confinement approach that demonstrated target energy gain at the U.S. National Ignition Facility in 2022. The company investigates alternative fuel cycles with the potential to eliminate tritium from the fuel cycle, and is pursuing cost-effective energy extraction technologies as a path to commercial viability. It is currently pre-revenue, with a roadmap targeting a fusion prototype facility by 2032 and a commercial fusion power plant by 2036.

Marvel Fusion's product surface today is best characterized as a portfolio of research infrastructure, enabling technologies, and a forward commercial concept rather than a shippable product. Operating assets include the LION 2 experimental chamber at LMU's Centre for Advanced Laser Applications (CALA) in Garching, the $160M ATLAS Facility under construction at Colorado State University (Fort Collins, Colorado) as a public-private partnership with the U.S. Department of Energy and Department of Defense, and the FusioTile consortium developing meter-scale pulse compression gratings with Carl Zeiss Jena and Fraunhofer IOF. The planned commercial offering is a fully integrated laser-based fusion power plant, jointly conceptualized with strategic partner Siemens Energy, which also contributed to the Series B extension. The company operates through its German headquarters (Marvel Fusion GmbH) and a U.S. subsidiary (Marvel Fusion Inc., established in Colorado in 2023 and led by Executive Vice President Puja Gupta from July 2025).

Marvel Fusion's business model is presently R&D-funded rather than revenue-generating. Capital sources total €385 million, comprising €170 million in private investment and €215 million in public cooperation projects, making it the best-funded European fusion company. Private backers include Earlybird (Series A lead, 2022), EQT Ventures, Siemens Energy Ventures, the European Innovation Council Fund, Tengelmann Ventures, and Bayern Kapital; public funding flows from BMFTR, the Bavarian state government, the U.S. DOE (INFUSE award, RISE hub), and the EIC (STEP Scale Up). Long-term commercial revenue is intended to come from selling zero-emission baseload fusion power, with potential earlier-stage licensing of laser-technology applications in defense, medical, and industrial markets. Customer-facing go-to-market today is effectively enterprise co-development with universities, national laboratories, and industrial partners — there are no end customers for fusion energy today, and the named relationships (CSU, LMU, Siemens Energy, TRUMPF, Thales) are R&D and design partners rather than revenue accounts.

Revenue model

1. Future commercial fusion power generation: Marvel Fusion is pre-revenue, aiming to build the world's first commercial fusion power plant in the 2030s. Long-term revenue model centers on selling competitive, zero-emission baseload power at scale once fusion ignition is commercially proven via a prototype targeted for 2032 and a commercial plant by 2036.
2. Diversified laser-technology applications: Marvel Fusion is exploring adjacent commercial applications for its high-power laser technology in defense, medical, and industrial sectors amid delays in fusion commercialization, which could provide earlier-stage revenue streams.
3. Public R&D and grant funding: Significant portion of the €385 million total raised (€215 million) is in public cooperation projects and government grants (German BMFTR, U.S. DOE INFUSE, Bavarian state, EIC Fund), supporting R&D rather than commercial revenue.

Core offering

Marvel Fusion develops laser-driven inertial fusion energy technology, combining a proprietary fast ignitor concept with innovations in lasers, targets, and power plant technology. The company is building toward a future commercial laser-based fusion power plant (jointly designed with Siemens Energy) that would deliver zero-emission baseload power, with a prototype targeted by 2032 and a commercial plant by the mid-2030s. Current activities include operating research infrastructure (LION 2 chamber at CALA, ATLAS facility at Colorado State University) and developing enabling hardware such as meter-scale pulse compression gratings.

Product overview

Marvel Fusion offers a single overarching product platform — laser-driven inertial fusion energy technology, combining a proprietary fast-ignitor concept with innovations in lasers, targets, and power plant technology, and pursued in collaboration with strategic partner Siemens Energy for the commercial power plant concept. Underpinning this core offering is a portfolio of named research programs, facilities, and enabling technologies: the LION 2 experimental chamber at CALA in Garching (for validating laser-matter interaction), the ATLAS Facility under construction with Colorado State University in Fort Collins (a $150M+ public-private partnership hosting multi-petawatt laser systems), the FusioTile consortium's meter-scale pulse compression gratings (enabling 100-joule laser systems), the DOE-funded RISE hub participation (for inertial fusion science and technology), and a planned Fusion Prototype Facility intended to scale to hundreds of lasers and reach ignition, with a commercial fusion power plant targeted for the mid-2030s. Together, these offerings span research infrastructure, enabling hardware, and a forward commercial product concept that target laser-driven, zero-emission baseload fusion energy.
