XSKY

XSKY星辰天合 is a Chinese data infrastructure company founded by Xu Xin roughly seven years ago as of 2022 reporting, specializing in software-defined storage (SDS) — a field Xu describes as enabling hardware to unlock new capabilities through software iteration, much like an iPhone running upgraded iOS versions . The company positions itself in the data infrastructure technology platform layer, aiming to help enterprises store, manage, and utilize data more efficiently rather than simply providing basic read-write storage .

In 2021, XSKY was selected as a national-level "Little Giant" enterprise under China's专精特新 program and raised over RMB 1 billion across two rounds that year, including a RMB 400 million Series F in December led by Source Code Capital and Yunhui Capital . By 2021, it held 390 intellectual property rights and approximately 70 core algorithm patents, and participated in drafting national standards for cloud storage and distributed storage . In the object storage segment specifically, IDC data cited in 2022 showed XSKY leading with a 19.7% market share, slightly ahead of Huawei's 19.4% . The company was preparing to launch its next-generation object storage system, codenamed "Chongming Bird" (重明鸟), in mid-2022, targeting single-bucket capacity exceeding 100 billion files .
