At EQT Ventures, we invest in bold ideas that we believe have the potential to reshape industries, rewire systems, and redefine what’s possible. Today, we’re proud to announce our investment in Marvel Fusion, a company working to solve one of the most profound scientific and engineering challenges of our time: laser-driven fusion energy. 

This is not just a bet on energy. It’s a bet on the next industrial backbone of the planet. A step toward what can be the most important energy transition in human history.

Fusion: The Next Big Leap

Human progress is inseparable from energy. From fire to steam to electricity, every leap forward has followed a leap in how we power our world. Today, we stand at the edge of the next breakthrough: fusion. The same process that powers the sun, now engineered for Earth.

Fusion is clean, safe, and effectively limitless. It produces no long-lived radioactive waste. It emits no carbon. It isn’t dependent on geography or weather. The output is reliable. If we get it right, fusion becomes the foundation of a radically more sustainable, resilient, and empowered world. So why hasn't it happened yet?

Why Marvel Fusion Stands Out

Fusion has been "30 years away" for the last 70. For decades, fusion efforts have centered on enormous magnetic reactors and complex systems that require vast infrastructure and long timelines. 

Marvel Fusion is taking a fundamentally different approach By using ultrafast, high-intensity lasers and nanostructured fuel targets, Marvel can trigger fusion conditions in a controlled, repeatable way. The path to a powerplant is path is faster to iterate and the fusion approach avoids many of the challenges that have delayed progress across the industry.

This is not a theoretical blueprint. Marvel is building real systems. They have partnered with leading laser facilities across Europe and the US, they are currently building a dedicated laser for fusion applications and they are developing with Siemens Energy the designs for the world’s first laser fusion power plant.

Marvel Fusion is led by a team of scientists, engineers, and entrepreneurs who combine deep technical expertise with a clear commercial mindset. The team — led by Moritz von der Linden, Georg Korn, Heike Freund, Hartmut Ruhl, and Nicolas Burkardt — has built a company that operates with both speed and scientific discipline. We have followed the Marvel Fusion closely for a few years now. And have been impressed by the team hitting milestone after milestone. Their strategy is grounded in rigorous simulation, systems engineering, and a clear industrialization roadmap. 

Why EQT Ventures Invested

The conditions are finally right. Advances in laser technology, high-performance computing, and material science have opened doors that were closed for decades. At the same time, the urgency for clean, sovereign energy has never been greater. Fusion is no longer a distant dream. It is a near-term race. And Marvel Fusion is one of the most serious contenders.

We back mission-driven founders with asymmetric ambition. We look for teams who don’t just chase disruption, but who seek to define the future. Marvel Fusion is exactly that kind of company.

Their clarity of vision, strength of execution, and commitment to scientific excellence set them apart. Their mission is to create a new energy paradigm, free from carbon, waste, and geopolitical dependency. That mission aligns deeply with EQT’s values of sustainability, resilience, and progress through innovation. We believe Marvel Fusion has the potential to become one of the most generation defining companies.

So What If It Worked?

Energy is not just one sector. It is every sector. From data centers to food systems, transportation to defense, everything depends on access to clean and reliable power. Now imagine that energy is available everywhere. Constant. Abundant. Emission-free. That is the future Marvel Fusion is building. And that is the future we are proud to support. If Marvel Fusion succeeds, the world changes. A planet powered without compromise. A climate restored. An economy unshackled from scarcity. A foundation for the next century of innovation and exploration.

We’re honored to be on this journey with Marvel Fusion.
