Daedal Systems and the Case for Shared Fusion Infrastructure

AI and electrification are significantly increasing power demand on a global scale. Goldman Sachs Research estimates that data center power demand will grow 160% by 2030. This growth is outpacing the rate at which utilities can add new energy capacity, suggesting that meeting it will require a mix of several energy sources. Beyond simply meeting demand, the environmental consequences of existing generation methods are increasing pressure to adopt cleaner sources of energy that can meet that demand sustainably. 

Nuclear power is emerging as one of the promising candidates to meet skyrocketing energy demand. There are two fundamentally different forms of nuclear power, fission and fusion. Nuclear fission splits a heavy atom (typically uranium) into smaller atoms which in turn releases energy. Fission is commercially established and powers most nuclear plants today. Nuclear fusion combines light atoms (usually hydrogen isotopes) into a heavier atom, releasing energy in a similar process as the sun. Fusion promises more abundant, low-carbon energy, but has yet to achieve commercial power generation. 

Nuclear fusion has long been dismissed as perpetually years away. Over the last decade, the underlying fusion science has crossed major validation milestones and achieved technical breakthroughs. This in turn has created a credible path to commercial fusion power. In December 2022, the National Ignition Facility achieved fusion ignition, producing more energy from the fusion reaction (than was required to trigger it). This was a significant turning point in the industry, as it indicated fusion could become a commercially viable source of power. (Simultaneously, private fusion investment has been heating up, reaching approximately $16.7B in cumulative funding in 2025). Governments globally have also committed over $15B toward near-term fusion technology development. 

Today there are more than 50 private companies building fusion reactors, all with slightly different reactor designs, confinement approaches, and timelines. Each of these fusion companies will ultimately need to adopt or develop measurement technology to validate the viability of their approach. Despite differing infrastructure, each fusion company will need to measure the same factors inside their machine: plasma temperature, density, neutron output, and magnetic field shape. The process of measuring these various attributes of a nuclear fusion machine is known as plasma diagnostics. Plasma diagnostic measurement infrastructure is not only integral to fusion technology development and the path to commercialization, but will also accelerate the pace at which these fusion companies can validate milestones and secure capital. 

Commonwealth Fusion Systems, the most well-funded company in the sector, operates 27 distinct diagnostic systems supported by a team of 50+ people. Maintaining these systems is both costly and time-intensive. Yet, diagnostics are rarely core to a fusion company’s IP or competitive advantage. The real differentiation lies in reactor architecture and the underlying approach to energy generation. For most companies in the industry, maintaining a 50-person diagnostics team simply isn’t feasible. They would rather direct those resources toward building and advancing their core reactor infrastructure.

Henry Gould, fusion expert and founder of Daedal Systems, saw the inefficiencies in plasma diagnostics first hand at General Fusion, a leading fusion company working on building a commercially viable reactor. Through this experience, Henry found that fusion companies choosing to build their plasma diagnostics in-house created significant delays, inefficiencies, and ultimately lower quality data that would be difficult for external partners and funders to validate. This experience is what led him to build Daedal Systems, the third-party measurement infrastructure for the fusion energy industry. 

Daedal develops both the hardware and software for standardized, modular diagnostic systems that let fusion companies outsource complex measurement rather than built in house. By delivering high-quality, third-party-validated measurements, Daedal helps companies accelerate R&D, focus on their core technology, and hit fundraising milestones. Since launch, Daedal has signed eight MOUs with fusion developers including Proxima Fusion, OpenStar Technologies, and Stellarex Energy Group. Selling into the R&D phase allows Daedal to generate revenue throughout the development journey to fusion, rather than waiting until commercial power plants are operational.

As Daedal spends the next several months building out it’s technology, the industry is poised for a major inflection point. In 2028, Commonwealth Fusion Systems plans to switch on SPARC which aims to hit the same outcome as NIF in 2022 but with a near-steady state device and clearer path to commercial viability. If SPARC succeeds, CFS plans to build ARC, a roughly 400 MW fusion power plant designed to deliver electricity to the grid. Other companies like Inertia were funded specifically to work to commercialize NIF’s breakthrough reaction. As companies race toward commercial viability, Daedal is positioned to become the industry's default measurement infrastructure and is already building inroads with key players. 

In July, Panache Ventures participated in Daedal’s oversubscribed $4M USD pre-seed round led by OMERS Ventures. Our thesis is simple :  if fusion becomes the source of clean, abundant baseload power the world needs as AI and electrification push demand to new highs, the companies building its foundational infrastructure will capture an outsized share of the value. Henry has lived this problem from inside one of the industry's leading fusion companies, and he's building the measurement layer that every reactor company will need to prove its machine works to investors, regulators, and customers. The fusion industry does not yet have an established supply chain, and whoever builds the measurement infrastructure the whole sector relies on will end up owning a critical piece of it. Daedal is uniquely positioned to capture this opportunity in fusion, but the underlying capabilities they are building to enable precise, validated measurement of extreme physical systems, is not unique to fusion. SMRs, semiconductor manufacturing, and aerospace all face versions of the same challenges. Daedal has the opportunity to build the measurement infrastructure layer for extreme physical systems, starting with the massive looming opportunity in nuclear fusion.  

About Daedal 

Daedal Systems is building the measurement infrastructure for the fusion energy industry. Daedal deploys standardized, modular plasma diagnostics and a shared analysis layer so that fusion companies can validate their technology without building in-house measurement capabilities. Daedal recently closed a $4M pre-seed led by OMERS Ventures, with participation from Panache Ventures, Garage Capital, Ripple Ventures, and Mars IAF. Learn more at https://daedalsystems.com/
