X Square Robot Hits $2.8 Billion Valuation After Four Funding Rounds

Founded in 2023, the company is pivoting away from traditional rule-based automation toward general-purpose embodied intelligence. Its proprietary WALL-B foundation model, built on the World Unified Model architecture, integrates vision, language, and action into a single network. This approach allows robots to navigate, reason, and act in complex, unpredictable environments rather than following rigid, pre-programmed paths.

CEO Wang Qian attributes the rapid growth to the company’s heavy investment in in-house model development and a scalable data pipeline. By automating data collection, annotation, and quality control, X Square Robot creates high-fidelity datasets that improve model performance over time. These capabilities are currently being tested in real-world scenarios, including partnerships with 58.com for residential cleaning services in Shenzhen and Beijing. Through its "X Family Member Program," the company is placing robots into homes for month-long trials, aiming to move beyond laboratory demos and into sustainable, everyday human-robot interaction.
