In a significant development for the burgeoning fusion energy sector, Lausanne-based startup Fusionality has successfully closed a $3.7 million (CHF 3 million) pre-seed funding round from prominent investors Founderful and Playfair. This crucial capital injection positions Fusionality at the forefront of a vital, yet underserved, segment of the fusion supply chain: the development of sophisticated control systems essential for managing the volatile conditions within experimental and future commercial fusion reactors. Founded by Federico Felici, who assumes the role of CEO, and Jonas Buchli, the company’s CTO, Fusionality is poised to address a persistent challenge voiced repeatedly by fusion companies globally: the urgent need for specialized, modular, and fusion-aware control system components.
Addressing a Critical Industry Void
The genesis of Fusionality stems from a direct observation by its founders, rooted in years of hands-on experience at the cutting edge of fusion research. Federico Felici recounted to TechCrunch the recurring sentiment from fusion companies: "We would ideally buy many of the components to make our control system, but there isn’t really anybody providing them – and especially there isn’t anybody who speaks the language of fusion." This vacuum in the market represents a substantial bottleneck for the acceleration of fusion energy, compelling each new fusion venture to independently develop complex control infrastructure from scratch, often duplicating efforts and diverting precious resources from core physics and engineering challenges.
The global race towards commercial fusion power, once a distant dream, has intensified dramatically in recent years, attracting billions in private investment. According to a 2023 report by the Fusion Industry Association (FIA), private fusion companies alone have collectively raised over $6.2 billion, signaling a robust belief in the technology’s eventual viability. However, this rapid growth has highlighted deficiencies in the supporting ecosystem. While some startups, like Kyoto Fusioneering, are innovating on specific components such as heat exchangers and tritium fuel cycle systems, and existing manufacturers are adapting to produce high-precision parts, a glaring gap has remained in the specialized hardware and software necessary to precisely govern the intricate processes within fusion reactors themselves. Fusionality aims to fill this void by offering a standardized yet adaptable suite of control systems and simulation environments, allowing fusion startups to focus their expertise on their unique reactor designs.
The Intricacies of Fusion Control
Fusion power promises a clean, virtually limitless energy source by replicating the process that powers the sun, where atomic nuclei fuse and release immense energy. This process typically occurs in a superheated plasma, a state of matter where electrons are stripped from atoms. In magnetically confined fusion – the primary focus for many leading private companies – powerful electromagnets are used to contain and shape this plasma, preventing it from touching reactor walls and maintaining the extreme temperatures (often exceeding 100 million degrees Celsius) required for fusion reactions to occur.
Maintaining these conditions is an extraordinary feat of engineering and real-time control. Plasmas are inherently unstable; even minute fluctuations in temperature, density, or magnetic field strength can lead to disruptions that halt fusion reactions. Therefore, the control systems must perform split-second decision-making, processing vast amounts of data from hundreds of sensors and actuating precise adjustments to magnetic coils, fuel injection, and heating systems. "Across the industry, many companies make their own control systems from scratch," Felici explained. "But actually, 80% of each company’s control system is really exactly the same." This observation forms the bedrock of Fusionality’s strategy: to build upon these common fundamental physics and engineering requirements, offering modular "Lego blocks" of technology that can be customized for specific reactor designs. This approach promises to significantly reduce development cycles and costs for individual fusion ventures.
A Foundation Forged in Deep Expertise and Collaboration
The synergistic expertise of Federico Felici and Jonas Buchli is central to Fusionality’s potential. Their professional paths converged through their shared commitment to developing novel methods for controlling experimental fusion devices. Felici, deeply embedded in fusion research at EPFL (École Polytechnique Fédérale de Lausanne) in Switzerland, worked with devices like the TCV (Tokamak à Configuration Variable) tokamak, a renowned experimental fusion reactor. Buchli, meanwhile, brought cutting-edge artificial intelligence and machine learning capabilities from his tenure at Google DeepMind, a global leader in AI research.
Their collaboration began while they were both teaching AI to control an experimental tokamak. Felici later joined Buchli at Google DeepMind, where he further honed his skills in developing simulations and machine learning interfaces specifically tailored for fusion devices. This unique blend of deep plasma physics knowledge, control engineering acumen, and advanced AI/ML expertise positions Fusionality to build highly sophisticated and efficient control solutions. Their collective experience, directly tackling the very problems their future customers face, provides an invaluable advantage in designing practical and effective systems.
The Evolving Role of Artificial Intelligence in Fusion
While AI has demonstrated transformative potential across numerous scientific domains, its application in the high-stakes environment of fusion reactor control requires a nuanced approach. Felici acknowledges AI’s significant future, stating it "will play an important role in future control systems." However, he maintains a cautious perspective regarding its immediate full autonomy: "I wouldn’t be somebody who advocates for AI to take the role of controlling the entire fusion reactor."
Instead, Fusionality envisions AI primarily as a powerful tool to "complement or enhance or optimize" parts of the system. In the context of fusion, this could translate to AI algorithms optimizing plasma confinement stability, predicting and mitigating disruptions before they occur, fine-tuning heating and fueling strategies for peak efficiency, or even accelerating the interpretation of complex diagnostic data. AI’s capacity for rapid pattern recognition and adaptive learning can significantly augment human operators and traditional control algorithms, leading to more stable, efficient, and safer reactor operations. As AI technology matures and gains greater robustness and explainability, its role may expand, but for now, its strength lies in augmenting, not entirely replacing, established control methodologies.
Strategic Focus and Market Expansion
Fusionality’s initial strategic focus is on magnetic confinement fusion, the most widely pursued approach in the private sector. This segment includes prominent startups such as Commonwealth Fusion Systems, Realta Fusion, Proxima Fusion, and Type One Energy, all actively developing devices like tokamaks and stellarators that rely on powerful electromagnets. By concentrating on this dominant branch, Fusionality can develop highly specialized and immediately applicable solutions for a significant portion of the burgeoning fusion industry. Felici has indicated that the company harbors ambitions to expand its offerings to other fusion approaches in the future, demonstrating a long-term vision for comprehensive industry support.
The CHF 3 million pre-seed funding will be instrumental in enabling Fusionality’s lean team, currently seven strong, to develop a "tightly selected number of technologies." Felici metaphorically describes these as "Lego blocks," indicating a modular approach. "We start with a few of these blocks and then we build out more," he noted, emphasizing the scalable nature of their product development. This targeted initial development allows the company to build a robust foundation of core technologies before expanding its portfolio. The ultimate ambition is clear: "We have the ambition to serve the really wide range of technology that you need to operate a fusion reactor."
Broader Implications for Fusion Commercialization
Fusionality’s emergence and successful funding round carry significant implications for the broader fusion energy landscape. By providing specialized, off-the-shelf, yet customizable control systems, Fusionality can dramatically accelerate the development timelines for fusion startups. Instead of each company expending valuable time and capital on developing proprietary control systems from the ground up, they can leverage Fusionality’s expertise, allowing them to allocate resources more efficiently towards their unique reactor designs, plasma physics research, and core engineering challenges. This division of labor is a hallmark of maturing industries and is crucial for bringing fusion energy to commercial viability faster.
Moreover, Fusionality’s offerings can help de-risk fusion projects. Standardized, professionally engineered control systems reduce technical uncertainties and provide a more reliable operational foundation. This increased reliability and efficiency can, in turn, make fusion projects more attractive to investors, further stimulating growth in the sector. The development of a robust supply chain, encompassing specialized components and services, is a critical step in transforming fusion from a scientific endeavor into a viable commercial industry capable of delivering clean, abundant power to the global grid.
