X Square Robot, a China-based developer of embodied artificial intelligence systems, said it completed four successive financing rounds that ended with a Series C, pushing the firm's valuation past RMB 20 billion (approximately $2.8 billion). The financing places the company among the highest-valued embodied AI startups in China.
IDG took part in the Series C round, the company said, while HongShan and Xiaomi provided backing in multiple earlier rounds. X Square Robot noted that lead investments through different stages also came from Meituan, Alibaba, ByteDance and Xiaomi, making it the only embodied AI company in China to have attracted lead-round support at various stages from four major domestic technology groups.
On the companys technical approach, founder and CEO Wang Qian was quoted directly: "Since day one, X Square Robot has focused on in-house development of foundation models, pursuing a challenging but necessary path," said Wang Qian, founder and CEO of X Square Robot. "Today, our investments in embodied AI models, scalable, model-driven high-quality data pipeline system and real-world deployment are beginning to deliver clear results."
Founded in 2023, X Square Robot develops end-to-end embodied AI platforms that integrate foundation models, robotics hardware and a proprietary data pipeline. The company intends to allocate the fresh capital toward core technology programs and foundational research in embodied intelligence.
In April 2026, X Square Robot introduced WALL-B, an embodied AI foundation model built on its World Unified Model architecture. The firm also open-sourced two model variants, WALL-OSS-0.5 and WALL-WM. According to the company, WALL-OSS-0.5 delivered over 80% autonomous completion on four out of 17 evaluated real-robot tasks without any post-training adjustments.
Deployment of the combined model and hardware stack is under way across household, industrial and logistics scenarios. Operational initiatives include a partnership with 58.com to roll out an AI-enabled cleaning service in Shenzhen and Beijing, where robots operate alongside human cleaners in residential settings. Since May, the company has been running the "X Family Member Program," a trial in which robots live with participating households for periods of up to one month as in-home companions.
The company description and recent activity underscore a dual emphasis on continued research into core model and data infrastructure and on scaling real-world applications across consumer and commercial settings. The firm did not provide additional financial terms beyond the valuation figure or a breakdown of how the funds will be allocated within specific projects.
