XSKY
星辰天合
XSKY (星辰天合) is a Chinese data-infrastructure company focused on software-defined storage (SDS), founded in 2015 by Xin Xu (胥昕), a post-90s technical founder who moonlights as an amateur racing driver and still serves as CEO . The company positions itself as an independent SDS player competing against incumbents like EMC, IBM, Huawei, and H3C, betting on flexible, scenario-specific delivery for customers such as insurers digitizing billions of policy documents — and spent nearly two years in R&D, backed by a compatibility lab and tens of thousands of automated test cases, before commercializing, per a Source Code Capital profile . It was named a national-level "specialized and sophisticated little giant" in 2021 and described as China's largest independent SDS company, closing a RMB 400 million Series F in December 2021 with Source Code Capital participating ; Qiming Venture Partners is also an investor, and as of mid-2025 Qiming's newsletters still list XSKY among its portfolio companies appearing on AI-cloud and Beijing digital-economy rankings .
