About

Cowboy Space, founded in 2024 by Robinhood co-founder Baiju Bhatt as Aetherflux, is developing vertically-integrated rockets with upper stages functioning as solar-powered AI data centers in low Earth orbit. The company raised $275 million in a Series B round led by Index Ventures at a $2 billion valuation to build infrastructure addressing the shortage of orbital data centers. Cowboy Space's business model centers on deploying orbital data centers that harness solar energy for AI workloads, enabling unique space-based computing and power generation solutions.
