Starcloud is a U.S.-based technology company that created the category of orbital data centers, designed to deliver artificial intelligence computing infrastructure in space. The company is building large-scale computing in orbit that draws on continuous solar power and radiative cooling, with the ability to scale without the land, energy and permitting constraints of terrestrial data centers.

Starcloud-1 launched in November 2025 carrying what the company describes as the first NVIDIA H100 GPU in orbit, and subsequently became the first spacecraft to train a large language model in space.

Starcloud was founded in 2024 by Philip Johnston, Ezra Feilden, and Adi Oltean, and is a Y Combinator company. In August 2026, Starcloud announced a USD $250 million Series A extension at a reported USD $2.3 billion post-money valuation, led by Manhattan West with participation from NVIDIA, Cisco Investments, Benchmark, EQT, Soma, NFX, and 776. The financing brings Starcloud's total capital raised to approximately USD $450 million. Planet Ventures holds an indirect position in Starcloud through ST-0504 Fund I.
