Type One Energy

Overview

Stellarator fusion startup, spun out of University of Wisconsin-Madison. Co-founders: Chris Hegna (VP optimization, UW-Madison professor), David Anderson (HSX stellarator director emeritus). CEO: Christofer Mowry. Technology: highly optimized stellarator with HTS magnets. Secured HTS magnet rights from CFS (MIT cable technology). Uses exascale supercomputers (Frontier at ORNL). $82.4M seed (July 2024), preparing $200M+ Series A (March 2025). Investors: Bill Gates' Breakthrough Energy Ventures, Foxglove, GD1, Centaurus Capital. Building Infinity One at retired TVA coal plant (~$220M investment). Infinity Two: baseline physics design. 6 peer-reviewed papers in Journal of Plasma Physics (March 2025) — 'no showstoppers.' DOE Milestone-Based Fusion Development Program recipient. Target: pilot plant by 2030.

Entity Type: Organization — Type One Energy operates as an institutional actor in the defense/aerospace ecosystem.

Campaign 136+ Round 165 (2026-08) hype audit: Series B is ANNOUNCED-ONLY ($174.5M claimed raised; no operating-co Form D found) and the Tennessee groundbreak is ANNOUNCED-ONLY (TDEC license application only, no construction authorization). Major premise correction: Type One pivoted from FRC to a stellarator concept, moved HQ to Oak Ridge, adopted a TVA OEM model, and re-anchored its grid to 2034. The FIA 'groundbreak in 2026' claim is falsifiable by 2026-12-31.
