Xiaosu Technology
小宿科技
Xiaosu Technology (小宿科技, also known as Cloudsway.AI) is an AI Agent infrastructure company co-founded and led by CEO William Du (杜知恒), a veteran of the PC-to-mobile search era at Baidu. Its core business is intelligent search built for AI Agents rather than humans — a search layer invoked by Agent products like Kimi, DeepSeek, and Manus — alongside a model aggregation platform, SkyRouter.ai, which connects to 100+ mainstream models, and compute services. Per a 十字路口Crossing interview, the company reported $25M ARR and positioned itself as an Agent Infra provider betting that inference compute demand would overtake training from 2025 onward. Yunqi Capital invested in 2025, citing the company's platform position in the Agent era, and as of September 2026 Yunqi described FUMO Lab, a Singapore frontier-model lab, as Xiaosu's sibling company.
