X Square Robot announced the closing of four consecutive financing rounds, culminating in a Series C that brought its valuation to more than $2.8 billion.
The company said the financing positions it among China’s highest-valued embodied AI startups.
X Square Robot is developing general-purpose embodied intelligence robots and foundation models for real-world environments.
The new funding will support the development of embodied AI foundation models, commercial deployments, and integrated robotics infrastructure.
The financing included a mix of strategic and financial investors, including technology companies, industrial partners, and venture capital firms.
IDG participated in the Series C round, while HongShan and Xiaomi have backed the company in multiple earlier rounds.
X Square Robot said that with earlier lead investments from Meituan, Alibaba, ByteDance, and Xiaomi, it has become the only embodied AI company in China to secure lead-round backing at different stages from four of the country’s leading technology companies.
Founded in 2023, X Square Robot develops end-to-end embodied AI systems that combine foundation models, robotics hardware, and a proprietary data pipeline system.
Instead of relying on traditional rule-based automation, the company’s approach is designed to help robots adapt to changing environments and generalize across a wide range of tasks.
X Square Robot is building a full-stack embodied AI system that combines foundation models, robotics hardware, a model-driven data pipeline, and real-world deployment.
At the center of the system is a general-purpose embodied AI model designed to enable robots to perceive, reason, and act in complex physical environments.
In April 2026, X Square Robot introduced WALL-B, an embodied AI foundation model built on its World Unified Model architecture.
The company said WALL-B differs from modular vision-language-action approaches by training perception, language, action, and physical prediction within a unified network. This is intended to support multimodal understanding, spatial reasoning, and continual learning from real-world interactions.
X Square Robot has also open-sourced WALL-OSS-0.5 and WALL-WM, extending its unified approach to robot manipulation and world modeling.
WALL-OSS-0.5 achieved more than 80% autonomous completion on four of 17 real-robot tasks without post-training, while WALL-WM introduces event-level prediction by aligning language, vision, and action data around meaningful events.
To accelerate model development, X Square Robot has built a scalable data pipeline spanning automated data collection, cleaning, annotation, quality control, and augmentation.
The company said this data infrastructure, combined with real-world deployments, enables rapid model iteration and the creation of high-quality datasets for complex and long-tail scenarios.
X Square Robot is deploying its model and hardware stack across household, industrial, and logistics scenarios.
In household applications, the company partnered with 58.com to launch an AI-powered cleaning service in Shenzhen and Beijing, where robots work alongside human cleaners in real residential environments.
Since May, the company has also launched the X Family Member Program, where robots live with users’ families for up to one month as household companions responding to everyday needs.
X Square Robot said these deployments move embodied robots beyond staged demonstrations and into real homes, creating a feedback loop in which operational data helps improve model performance.
The company’s robots are designed for long-horizon tasks across home and everyday environments, research and education, logistics and warehousing, and industrial operations.
KEY QUOTES:
“Since day one, X Square Robot has focused on in-house development of foundation models, pursuing a challenging but necessary path. 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.”
“As AI moves beyond digital experiences into the physical world, progress will depend on close integration between models, data and robotics. We’re building that foundation so embodied AI can become part of everyday life.”
Wang Qian, Founder and CEO of X Square Robot
