Starcloud

Starcloud designs and operates satellites that function as high-performance data centers in orbit, offering compute infrastructure for artificial intelligence workloads. The company's architecture leverages continuous solar energy and the vacuum of space as a passive heat sink to enable sustained operation of consumer-grade GPUs without traditional cooling systems. Starcloud-1, a demonstration satellite launched in November 2025, successfully trained a large language model in orbit and carried an Nvidia H100 GPU—the first time commercial AI-grade processors have operated in space. The company is developing planned follow-on missions carrying multiple Nvidia H100 chips and the Blackwell platform.

Starcloud operates on an infrastructure-as-a-service model, providing customers with on-orbit compute cycles and data processing capabilities through partnerships including Crusoe Cloud and Capella Space. The company's long-term vision targets megawatt-scale orbital data center clusters to bypass terrestrial constraints related to land availability, permitting, and grid energy supply. Founded in 2024 by a team with experience from SpaceX, Microsoft, and Airbus Defence & Space, Starcloud is headquartered in Redmond, Washington and is backed by investors including Nvidia, In-Q-Tel, NFX, and venture scouts from Andreessen Horowitz and Sequoia.
