Fusionality Raises CHF 3M Pre-Seed for Fusion Control Software

Fusionality Secures CHF 3 Million Pre-Seed Round

Fusionality, a Lausanne-based operations-technology company, has raised CHF 3 million in pre-seed funding. The round was led by Founderful, with participation from Playfair Capital.

What Fusionality Does

Fusionality builds integrated measurement, plasma-control, data and rapid-simulation software for fusion devices. The company was spun out of EPFL's Swiss Plasma Center, giving it roots in one of Europe's established fusion research environments.

Rather than treating these capabilities as one-off, device-specific projects, Fusionality supplies the diagnostics-to-control software stack as reusable infrastructure. The goal is to let fusion developers avoid building these capabilities in-house, which can be a significant engineering undertaking for any fusion program.

The company's scope spans the full path from diagnostics through to control, alongside data handling and rapid simulation. Together, these functions sit at the center of how a fusion device is operated and how its performance is understood and improved.

Founding Team

Fusionality was founded in 2026 by Federico Felici and Jonas Buchli. Both founders were formerly of Google DeepMind, bringing experience from one of the world's leading AI research organizations into the fusion software space.

The combination of deep fusion research heritage through EPFL's Swiss Plasma Center and applied AI experience from DeepMind shapes the company's positioning: software infrastructure for fusion, built by a team familiar with both plasma science and advanced computational methods.

Why the Software Layer Matters

Fusion development is capital-intensive and technically demanding. Alongside the hardware challenges of building and operating fusion devices, developers face a substantial software burden: measurement and diagnostics, plasma control, data management, and simulation all need to work together reliably.

Fusionality's approach is to make that stack reusable rather than bespoke. For fusion developers, that can mean focusing internal resources on their core device programs while relying on proven, shared infrastructure for the diagnostics-to-control layer.

Round Details

Acquisition Perspective

Fusionality occupies a distinct position in the fusion technology landscape. It is not a device developer; it is an infrastructure provider whose software stack is intended to serve multiple fusion developers. That positioning can be relevant to acquirers interested in the enabling layer of the fusion ecosystem rather than in a single device program.

The company's origins at EPFL's Swiss Plasma Center and its founders' backgrounds at Google DeepMind are central to its story. For strategic buyers in energy technology, industrial software, or advanced computing, Fusionality represents an early-stage asset built around reusable software infrastructure for a technically complex and growing sector.

At pre-seed, the company is at the beginning of its commercial journey. The CHF 3 million round, led by Founderful with Playfair Capital participating, provides the initial capital to develop and position its diagnostics-to-control software stack for fusion developers.
