Summary
Starcloud builds data centers in space to provide GPU compute for AI training and inference. Founded by Philip Johnston (repeat founder, ex-McKinsey satellite consultant), Ezra Feilden (satellite design expert from Airbus), and Adi Oltean (ex-SpaceX Starlink engineer who deployed early LLMs at Microsoft), they solve the energy and cooling constraints of Earth-based data centers by using solar power and radiative cooling in orbit. In November 2025, they launched Starcloud-1 with an Nvidia H100, becoming the first to train an LLM in space and run Gemini on orbit. Their second satellite launches in October 2026 with 100x more power generation.
