Marvel Fusion develops laser-driven fusion energy using non-thermal direct-drive inertial confinement with nanostructured fuel targets. It aims to trigger fusion reactions with low-neutronic fuels like hydrogen-boron, reducing long-lived radioactive waste. The company builds a new high-powered laser facility in collaboration with Colorado State University, housing multiple multi-petawatt lasers to conduct experiments and advance fusion research. Its approach differs from many competitors by applying direct-drive laser for fusion with nanostructured fuels and a focus on hydrogen-boron to minimize waste, supported by a strong academic and private funding network. The goal is to enable a safe, clean, and reliable fusion power plant that helps the world move toward sustainable energy.

Simplify's Take
What believers are saying
- Siemens Energy and EIC joined March 2025, validating Europe-led financing momentum.
- CSU says ATLAS reaches substantial completion in December 2026, advancing toward experiments.
- Marvel Fusion now claims €385 million total funding, giving it Europe's strongest fusion war chest.
What critics are saying
- ATLAS slipped from 2026 to early 2027, delaying proof before investors.
- Commercial rollout still targets 2036, leaving a decade-plus capital burn ahead.
- NIF and private rivals advance alternative fusion paths, compressing Marvel Fusion's relevance window.
What makes Marvel Fusion unique
- Marvel Fusion pairs proprietary fast-ignitor lasers with nanostructured targets, unlike tokamak rivals.
- Siemens Energy joined in 2025, adding industrial power-plant design credibility.
- ATLAS at CSU creates a rare U.S. testbed for high-repetition fusion validation.

↓ -6%Marvel Fusion, a Munich-based energy start-up, secured €113 million in venture capital funding. The company is researching laser-enabled nuclear fusion to create clean energy, with Siemens Energy leading the financing round.
Marvel Fusion, a Munich-based fusion startup, expanded its Series B funding round by €50 million, bringing the total to €113 million. New investors include EQT Ventures, Siemens Energy Ventures, and the European Innovation Council Fund, marking their first investment in fusion energy. Existing investors Tengelmann Ventures and Bayern Kapital also participated. This raises Marvel Fusion's total funding to €385 million, making it the best-funded European fusion company.
WunderGraph has raised $7.5 million from eBay Ventures, Karma Ventures, and Aspenwood Ventures. The startup, founded in 2020 by Dustin Deus, Jens Neuse, Björn Schwenzer, and Stefan Avram, is an open-source GraphQL federation solution. The company is currently profitable and has a team of under 20 people.
EQT Ventures and Siemens Energy among new backers in Munich-based start-up’s latest funding round
In September, venture activity surged with significant photonics funding. Marvel Fusion secured a €63M Series B led by HV Capital, focusing on inertial confinement fusion. Quantum Source raised $50M in a Series A for photonic quantum computers, while Italian startup Ephos garnered $8.5M in Seed funding. MedTech firm SpectraWave obtained $50M in Series B funding. AttoTude, a networking startup, announced a $29M Series A led by Sutter Hill Ventures.
