6 The Hiring and Company Growth

Marvel Fusion's Team Growth and Hiring Strategy Post-EIC Accelerator Funding Since securing EIC Accelerator funding in March 2024, Marvel Fusion has accelerated its hiring and R&D efforts to transition from research to industrial deployment. The company’s headcount has grown significantly, with recent reports indicating 51–200 employees, though more specific figures suggest approximately 69 employees as of 2023–2024, with a 41% year-over-year employee growth rate. This expansion aligns with its €113 million Series B extension (March 2025), which includes backing from Siemens Energy Ventures and EQT Ventures.

Current Hiring Focus
While direct job postings are not explicitly detailed in public reports, Marvel Fusion is actively scaling its technical teams. Key roles likely include laser physicists, fusion engineers, and materials scientists to support its $150 million laser facility partnership with Colorado State University. The company emphasizes industrial partnerships for scaling production, suggesting increased hiring in manufacturing and systems integration roles.

Growth Trajectory and Strategic Impact
Marvel Fusion’s workforce growth supports three critical milestones:

• Laser facility development: Construction of the Colorado-based facility aims to validate fusion processes by 2026.
• Power plant design: Collaboration with Siemens Energy on heat transfer systems requires specialized engineering talent.
• Fuel target innovation: Proprietary nanostructured fuel targets demand expertise in nanotechnology and plasma physics.

The addition of experts like Nobel laureate Gérard Mourou (scientific advisor) underscores its focus on cutting-edge R&D, while partnerships ensure cross-industry knowledge transfer. No leadership changes have been reported since the 2019 founding team—Moritz von der Linden (CEO), Pasha Shabalin, Georg Korn, and Karl-Georg Schlesinger—remains intact.
