X Square Robot Announces Series C Funding and $2.8 Billion Valuation
X Square Robot, an embodied AI startup founded in 2023, disclosed the closing of four consecutive financing rounds, the latest being a Series C that lifts its post‑money valuation to over US$2.8 billion (approximately RMB 20 billion). The funding round brings together a mix of strategic and financial investors. IDG participated in the Series C, while HongShan and Xiaomi have backed the company in multiple earlier rounds. Earlier lead‑round investors include Meituan, Alibaba, ByteDance and Xiaomi, making X Square Robot the only Chinese embodied AI company to receive lead‑round backing at different stages from four of the country’s leading internet technology firms.
Leadership Commentary
Founder and Chief Executive Officer Wang Qian stated that the company has always focused on in‑house development of foundation models and that the new capital will be deployed to deepen core technology research, accelerate the creation of general‑purpose embodied AI, and expand real‑world deployments.
Technology Milestones
In April 2026 the firm introduced WALL‑B, an embodied AI foundation model built on its World Unified Model (WUM) architecture. Unlike modular approaches that separate vision, language and action, WALL‑B trains perception, language, action and physical prediction within a single unified network, delivering stronger multimodal understanding, spatial reasoning and continual learning from real‑world interactions. The company also open‑sourced WALL‑OSS‑0.5 and WALL‑WM. WALL‑OSS‑0.5 achieved more than 80 % autonomous completion on four of 17 real‑robot tasks without any post‑training, while WALL‑WM adds event‑level prediction by aligning language, vision and action data around meaningful events, enhancing cross‑modal learning and physical‑world prediction across reasoning, manipulation and generalisation tasks.
Scalable Data Pipeline
X Square Robot has built a model‑driven data pipeline that automates data collection, cleaning, annotation, quality control and augmentation. Coupled with real‑world deployments, this pipeline enables rapid model iteration and the generation of high‑quality datasets for complex, long‑tail scenarios.
Real‑World Deployments
The company is rolling out its hardware and model stack across household, industrial and logistics environments. In the household segment, X Square Robot partnered with 58.com to launch an AI‑powered cleaning service operating in Shenzhen and Beijing, where robots work alongside human cleaners in actual residential settings. Since May 2026, the firm also launched the "X Family Member Program," allowing robots to reside with user families for up to one month as household companions, thereby extending the range of everyday tasks the robots can perform.
Use of Proceeds
Proceeds from the financing will be allocated to further investment in core embodied‑intelligence technologies, foundational research, and scaling of the full‑stack embodied AI system to accelerate progress toward general‑purpose robots that can operate safely and effectively in physical environments.
