Aetherflux / Cowboy Space Corporation

Summary

Rebranded from Aetherflux to Cowboy Space Corporation in May 2026 after a $275M Series B at $2B valuation. Building a LEO data-centre constellation with space-based solar power ("Galactic Brain"); DOD funding approved for a White Sands demo in June 2026 and an FCC filing for a 20,000-satellite "Stampede" constellation followed six days after the round.

Highlights

• DOD funding via OECIF approved; White Sands demo June 2026
