realta-fusion // Intelligence Entity

Summary

Magnetic mirror fusion startup, spun out of University of Wisconsin-Madison (~2022). Technology: compact, scalable, modular magnetic mirror with HTS magnets — 'fusion in a bottle.' WHAM experiment (Wisconsin HTS Axisymmetric Mirror): 17 Tesla HTS magnets (world record for magnetic confinement), first plasma July 15, 2024. Initially $10M ARPA-E grant (2020) to UW-Madison, MIT, and CFS. Now public-private partnership with Realta. $36M Series A (May 2025) led by Future Ventures. Previous: $9M seed from Khosla Ventures. 18 employees. Building CoSMo prototype and 'Realta Forge' facility. CEO: Kieran Furlong. DOE Milestone-Based Fusion Development Program recipient. Lineage: Project Sherwood (LLNL, magnetic mirror/Richard Post) → WHAM → Realta Fusion.
