Nullspace: $2.5 Million Seed Funding Raised For Electromagnetic Simulation Software

By Amit Chowdhry ● Aug 21, 2025

Nullspace, a deep tech company dedicated to developing advanced electromagnetic simulation software, has announced the successful completion of a $2.5 million seed funding round. Fathom Fund led this funding round, with participation from Golden Seeds and several strategic angel investors.

As we move into an era defined by increased connectivity driven by the deployment of 5G technology, the development of AI chips, and advancements in electronic warfare, the demand for radio frequency (RF) performance is experiencing rapid growth. Moreover, as quantum computing advances towards commercialization, this emerging market is anticipated to hold substantial growth potential, with industry leaders competing to introduce viable systems to the market.

Nullspace is creating enterprise simulation software that stands out due to its ability to address two high-growth and high-barrier markets: the next generation of RF technology and the hardware needed for quantum computing. The company’s innovative approach is designed to meet the demands of engineers across these critical sectors.

As part of this funding round, Sheng from Fathom will join the Nullspace board of directors, bringing valuable expertise and insight. Additionally, Dr. Nathan Kundtz, the CEO and founder of Rendered AI and previously the CEO and co-founder of Kymeta Corporation, will join as an independent board director. Dr. Kundtz’s experience in both the defense and technology sectors will likely enhance Nullspace’s strategic direction.

The significance of radio frequency technology cannot be overstated; it underpins numerous innovations that drive modern life. RF technology is crucial in various applications, including smartphones, autonomous vehicles, 5G networks, satellite constellations, and many modern defense systems.

However, many of the simulation software tools currently in use by engineers tasked with designing these connected technologies are outdated and cumbersome, creating significant design bottlenecks. Nullspace seeks to address this issue by providing modern, fast, and accurate simulation software. Its flagship product, Nullspace EM, fundamentally enhances the ability to simulate larger and more complex designs while maintaining high fidelity in accuracy and speed.

Beyond improving RF simulation, Nullspace also offers Nullspace ES, the only commercial tool available for designing and analyzing large ion traps used in quantum computing architectures. This capability is essential, as quantum computing is set to revolutionize numerous industries.

Nullspace is uniquely positioned with its software catering to dual-use applications in both military and commercial sectors. Built on modern implementations of numerical methods, the company’s simulation tools are being developed for real-world enterprise RF applications. This gives Nullspace an edge in advanced implementations such as generative design and AI-guided design automation.

The competitive advantage of Nullspace stems from over a decade of development at IERUS Technologies, a recognized defense contractor specializing in the creation of hardware and software solutions for electromagnetic, analytical computing, and weapons systems technologies.

The core technology underpinning Nullspace’s innovative solvers has been rigorously tested against real-world challenges, including antenna, microwave, scattering, and ion-trap design problems over more than ten years. Notably, physical products developed using this technology have been delivered to the U.S. Department of Defense, highlighting the reliability and applicability of their solutions in critical defense applications.

KEY QUOTES:

“Nullspace will utilize this seed funding to expand the engineering team, accelerate product development, and scale go-to-market efforts as we target growing demand across aerospace, defense, quantum computing, and AI-enabled hardware markets.”

Dr. Masha Petrova, Nullspace’s CEO and co-founder

“At Fathom, we seek out companies that combine deep technical moats with clear paths to market dominance, and Nullspace is a great example of that. The founders’ PhD-level engineering backgrounds, combined with their extensive operational track records, have enabled them to build software solutions with an extraordinary level of maturity.”

“Nullspace is delivering much-needed modern physics simulation tools that customers are welcoming with open arms. In rapidly evolving markets like 5G, quantum computing, and spectrum management, this head start is invaluable.”
