Sand AI (also written Sand.ai or 三代科技) is a Chinese AI company founded in January 2024 by Cao Yue, who previously served as a co-founder alongside Wang Huiwen at the short-lived startup Light Years Beyond . Cao was formerly a lead researcher at Microsoft Research Asia . The company received an early-stage investment from Kathy Xu's Capital Today, which Xu cited to rebut rumors that her firm had exited primary-market investing entirely . Source Code Capital also counts Sand AI among its portfolio companies , and the firm appears in lists of representative AI investments alongside Kimi, Ubtech, and Galbot . According to a 2025 interview, Cao described himself during the turbulent Light Years Beyond period as "a tree in winter" — outwardly still while quietly taking root .
