Starcloud
Type: Orbital data center provider
Status: Active (Series A, March 2026)
Headquarters: San Francisco, CA
Backing: Y Combinator
Overview
Starcloud develops orbital data centers (ODCs) for AI compute workloads, positioning space as offering superior economics through unlimited solar power (>95% capacity factor) and free radiative cooling. Company slogan: "demand for compute outpaces Earth's limits."
Three-Tier Roadmap
| Satellite | Launch Vehicle | Launch Date | Capability |
|---|---|---|---|
| Starcloud-1 | Falcon 9 rideshare | November 2025 | 60 kg SmallSat, NVIDIA H100, first AI workload in orbit (trained NanoGPT on Shakespeare, ran Gemma) |
| Starcloud-2 | Falcon 9 dedicated | Late 2026 | 100x power generation over Starcloud-1, NVIDIA Blackwell B200 + AWS blades, largest commercial deployable radiator |
| Starcloud-3 | Starship | TBD | 88,000-satellite constellation, GW-scale AI compute for hyperscalers (OpenAI named as target customer) |
Technology
Thermal Management: Proprietary radiative cooling system claiming $0.002-0.005/kWh cooling costs versus terrestrial data center active cooling. Starcloud-2 will test the largest commercial deployable radiator ever sent to space.
Target Market: Hyperscale AI compute providers. OpenAI explicitly named as target customer for Starcloud-3 constellation.
Timeline
- November 2025 — Starcloud-1 launched on Falcon 9 rideshare. First orbital AI workload demonstration (trained NanoGPT on Shakespeare, ran Google's Gemma LLM).
- March 30, 2026 — Raised $170M Series A at $1.1B valuation. Largest funding round in orbital compute sector to date.
- Late 2026 — Starcloud-2 scheduled launch on dedicated Falcon 9. 100x power increase, first commercial-scale radiative cooling test.
- TBD — Starcloud-3 constellation deployment on Starship. 88,000-satellite target, GW-scale compute. No timeline given, indicating dependency on Starship economics.
Strategic Position
Starcloud's roadmap instantiates the tier-specific launch cost threshold model: rideshare for proof-of-concept, dedicated launch for commercial-scale testing, Starship for constellation economics. The company is structurally dependent on Starship achieving routine operations for its full business model (Starcloud-3) to activate.
