5, 2026 A Chinese AI chip startup you’ve probably never heard of just stepped into the spotlight, and its entire business model is built around one goal: making US export controls irrelevant. Dongfang Suanxin, founded in 2024 and headquartered in Shanghai’s Zhangjiang hi-tech zone, officially exited stealth mode in early July 2026 by launching its corporate website and social media presence. The company is developing 3D-stacked near-memory computing chips, an architectural approach that could let it build high-performance AI accelerators without relying on the advanced foreign technology Washington has been trying to keep out of Chinese hands.

Advertisement The tech behind the strategy The company’s DF1000 series AI accelerators use what’s called 3D near-memory computing architecture. Instead of shuttling data back and forth between memory and processor, the chip stacks computing and memory layers on top of each other. This approach, combined with what the company describes as “software-defined chips,” is designed to achieve competitive AI processing performance using a fully domestic supply chain.

The company is led by Wei Shaojun, a semiconductor veteran and professor at Tsinghua University. The DF1000 series exists as a concept and prototype, not as a product shipping to data centers. Follow the money Dongfang Suanxin completed its Series A+ funding round in late April 2026, achieving a post-money valuation of approximately 12.

275 billion yuan, roughly $1.7B at current exchange rates. The investor list includes the National Artificial Intelligence Industry Investment Fund, a state-affiliated vehicle, along with the venture arms of Xiaomi and JD.
