PRESS RELEASE — Nullspace, a deep tech company developing electromagnetic simulation software, announced a $2.5 million seed round led by Fathom Fund, with participation from Golden Seeds LLC and other strategic angel investors.
“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,” said Dr. Masha Petrova, Nullspace’s CEO and co-founder.
Nullspace Offers RF and Quantum Computing Tools
In an increasingly connected world driven by 5G deployment, AI chip development, and electronic warfare – the demand for radio frequency (RF) performance is rapidly increasing. Meanwhile, as quantum computing advances toward commercialization, this emerging market holds immense growth potential as industry leaders race to bring viable systems to market.
Nullspace develops enterprise simulation software, uniquely positioned to address both high-growth, high-barrier markets: next-generation RF and quantum computing hardware.
“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,” said Dr. Paul Sheng, managing partner at Fathom Fund. “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.
Sheng continued, “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.”
Fathom’s Sheng will be joining the board of directors at Nullspace. In addition, Dr. Nathan Kundtz, CEO and founder of Rendered AI, and former CEO and co-founder of Kymeta Corporation, will join as an independent board director.
Why Now: RF and the Ubiquity of Connected Devices
Today, RF technology is everywhere – it underpins the innovations that power modern life, from smartphones and autonomous vehicles to 5G networks, satellite constellations, and most modern defense applications.
Yet, legacy simulation software tools used by engineers designing these connected technologies are cumbersome and outdated. Nullspace is solving this critical design bottleneck by delivering modern, fast, and accurate simulation software. Its flagship product, Nullspace EM, fundamentally unlocks the ability to simulate larger, more complex designs with full-fidelity accuracy and speed.
At the Frontier of Quantum Computing
Beyond transforming RF simulation, Nullspace also offers Nullspace ES – the world’s only commercial tool for design and analysis of extremely large ion traps for quantum computing architecture.
Dual Use: Defense-Validated Technology with Enterprise Traction
Developed on modern implementations of numerical methods, Nullspace is a U.S.-based company developing real-world enterprise RF simulation tools.. This foundation enables the dual use of Nullspace software for both military programs and commercial applications, uniquely positioning it for advanced implementations like generative design and AI-guided design automation.
Nullspace’s competitive advantage stems from more than a decade of development through IERUS Technologies, a defense contractor specializing in hardware and software development of electromagnetic, analytical computing, and weapons systems technologies.
The core technology behind Nullspace’s modern solvers has been rigorously tested on real-world antenna, microwave, scattering, and ion-trap design problems for 10+ years, including physical products delivered to the U.S. Department of Defense.
