Infinite Space
无限宇航
Infinite Space (北京无限宇航科技有限公司) is a Beijing-based commercial space infrastructure provider founded in 2023 that builds orbital transfer vehicles and on-orbit servicing capabilities . The company, led by founder Li Jian — who previously worked on the world's first active space debris removal spacecraft — has developed a "Space Bus" (太空巴士) series of OTVs designed to solve satellite deployment's "last-mile" problem by transporting satellites from shared initial orbits to their precise target orbits, including heterogeneous deployment, multi-satellite ride-share launches, and constellation intelligent deployment .
The company's technical stack centers on propulsion, guidance/navigation/control, and space operations, including domestically leading regenerative-cooled 300N orbit-change engines and a high-precision GNC system with future rendezvous-and-docking extensibility . In March 2025, Infinite Space completed full-system ground hot-fire testing of its IH-1 vehicle, becoming China's first OTV to pass complete ground verification and reach flight-ready status .
The company has raised three disclosed rounds: an angel round led by Unity Ventures (九合创投) with Inno Angel Fund participation in March 2025 ; a Pre-A round of tens of millions of RMB led by Shenzhen Guarantee Ventures (深担创投) with four co-investors in late 2025 ; and a Series A of nearly 100 million RMB led by Dingfeng Sci-Tech Innovation (鼎峰科创) in August 2026, with existing shareholders re-upping .
