Starcloud

Solar-powered data centers in orbit — running NVIDIA GPUs in space
Starcloud (formerly Lumen Orbit) is a Redmond, Washington startup building solar-powered data centers in orbit, aiming to run AI compute on satellites where continuous solar energy and radiative cooling into the vacuum of space offer near-limitless power and passive cooling. Founded in January 2024 by Philip Johnston (ex-McKinsey), Adi Oltean (ex-SpaceX, Microsoft Azure) and Ezra Feilden (ex-Airbus Defence and Space), the Y Combinator (S24) company launched Starcloud-1 in November 2025 — the first NVIDIA H100 GPU operated in orbit, which it says trained an LLM and ran a version of Google's Gemini in space. Its $170M Series A (March 2026), co-led by Benchmark and EQT Ventures, valued the company at $1.1B and made it the fastest company in YC history to reach unicorn status. The follow-on Starcloud-2 mission will fly an NVIDIA Blackwell GPU cluster with payloads from AWS, Google Cloud, NVIDIA and Crusoe.
