The brief
- Raised $60M ($10M seed + $50M Series A); closed $275M Series B in May 2026 at $2B valuation, rebranding to Cowboy Space.
- First Galactic Brain satellite targeted for Q1 2027, providing multi-gigabit compute services.
- Pivoted from solar-power transmission to orbital data centers, where space-sunlight and natural cooling cut costs.
Technical approach
Solar panels in permanent daylight
Satellites orbit in sunlight 70% of the time, unlike Earth which has nighttime. Solar cells generate continuous power without weather interruption.
Vacuum as infinite radiator
Satellites shed heat directly into space at absolute-zero temperatures. Data center chillers use 30% of ground facility power; space needs none.
Latency-tolerant workloads
Targets AI inference and batch computing. Data uplinks feed models; results beam down to Earth.
30–100+ satellites per launch
Launches via Falcon 9 (~30 per mission) and Starship (100+) let Aetherflux scale capacity. Older satellites handle lower-priority work as they age.
