SUNMMIO
算苗科技
SUNMMIO (算苗科技) is an early-stage Chinese startup developing 3D computing chips for AI workloads, founded with a focus on domestic 3D compute chip R&D and mass production . In early 2026, the company completed two consecutive funding rounds totaling nearly 1 billion yuan: a Pre-A1 round led by Xiang He Capital with participation from state-backed investors including Guokai Financial and Beijing Shunxi, and a Pre-A round co-led by Source Code Capital and ShiXi Capital . Source Code Capital managing director Zhang Xun has taken a leading role in the investment, with the firm backing SUNMMIO's bet that 3D IC architecture—moving beyond 2.5D—can establish a new paradigm for AI chips .
