An AI Startup Says It's First to Put a '4D World Model' in a Real Store. The Partner Won't Go on the Record.

Sota Wujie, founded in April 2026, says it has signed Europe's largest supermarket group to host training of its embodied-AI robots, a four-dimensional world model the company describes as "native" to real retail rather than simulated first. The retailer's name is not on the record in any Chinese-language coverage, and the figure most often repeated, more than 1,000 robots deployed over three years, is a company-stated plan, not a contracted fleet.

Founder Hu Debo, an ex-Huawei Europe executive and former Kepler Robotics co-founder, has built his third venture around a vertical-first training strategy. Chief scientist Liu Zhe, a HUST PhD and HKU postdoc with more than 2,380 Google Scholar citations, anchors the technical side. The pair frame supermarket aisles as the highest-fidelity bridge between factory robotics and home service, and Europe's data-localization environment as a structural moat around the dataset.

The bet runs against the simulation-first approach most major embodied-AI efforts have converged on, including Wayve, NVIDIA's Cosmos and GR00T, Physical Intelligence, and Tesla. If real-shelf data does not generalize beyond the aisle, the strategy loses; if it does, the company holds a vertical dataset competitors cannot easily replicate.

Sota Wujie signed the project at WAIC 2026 as a Shanghai municipal AI key project.
