Summary

Thea Energy, a Princeton-based fusion startup, has raised an oversubscribed $100 million Series B round led by the U.S. Innovative Technology Fund, bringing total private investment to $130 million. The funding will support expanded manufacturing of their uniquely designed tunable rectangular magnets and the start of construction on Eos, a power-plant-relevant demonstration device, beginning next year. The company previously completed a $20 million Series A in early 2024. Thea's rectangular magnets can be tuned to form the overall magnetic field, likened to pixels, which is central to their fusion reactor design for confining superheated plasma.
