## About

Based in New Jersey, US and founded in 2022 by Brian Berzin (CEO), David Gates (CTO) and Matt Miller. Thea Energy, Inc. formerly known as Princeton Stellarators, Inc., develops fusion energy systems for the renewable power sector. In August 2026, Thea Energy, Inc. received series B funding from Brevan Howard Macro Venture, Aloniq, ALJ Investments and Beyond Earth Ventures. This round was part of a larger Series B funding.
The company works with enterprise and industrial energy stakeholders to provide fusion power solutions based on stellarator technology. Its offerings include planar coil stellarator systems, dynamic magnet control software, and integrated fusion platforms such as the Eos neutron source and Helios power plant. These systems utilize arrays of mass-manufacturable magnets controlled via advanced computational software to generate stable magnetic fields for plasma confinement. The company’s engineers, physicists, and software specialists develop scalable energy systems designed for continuous operation. Its solutions target utilities, research institutions, and industrial users seeking sustainable, zero-emission energy alternatives.
The company will use the August 2026 funding to expand magnet production, develop an additional facility in Northern New Jersey, advance the Eos fusion system, and support the commercialization of its Helios power plants.
