Overview
Cowboy Space Corporation (rebranded from Aetherflux) is building orbital infrastructure including space-based solar power transmission and data centers for AI compute. Founded by Robinhood co-founder Baiju Bhatt, the company raised ~$50M Series A in 2025 led by Index Ventures and a $275M Series B in 2026 at a $2B valuation with NEA and a16z participating. The thesis: orbital solar avoids terrestrial land constraints and could eventually host energy-intensive AI workloads.
Why Cowboy Space Corporation is interesting
Robinhood co-founder Baiju Bhatt targets orbital AI compute — Index led a $275M Series B at $2B with NEA and a16z as space infra meets the AI power crunch.
Product & use cases
Cowboy Space develops orbital platforms for wireless power transmission and space-based compute — combining aerospace engineering with energy infrastructure.
- Space-based solar power beamed to Earth receivers
- Orbital data centers leveraging continuous solar exposure
- Defense and commercial satellite power infrastructure

Competitive landscape
Edge: Founder capital and profile (Bhatt/Robinhood) plus Index/NEA backing at scale rare for early orbital infra startups.
Space-based solar and orbital compute are decades-old concepts with renewed interest from AI power demand. Cowboy Space has unusual fundraising velocity but faces massive technical and regulatory hurdles. Success depends on launch cost curves and proof of power-beaming economics.
