The fact that investors affiliated with both Lei Jun - founder of Xiaomi - and Jack Ma - founder of Alibaba - joined the same funding round is itself a signal. These are not funds that typically co-invest in the same deals. Their shared conviction in Spirit AI's latest $145 million round, co-led by Shunwei Capital and Yunfeng Fund, says something about how seriously China's tech establishment is taking embodied AI.
The new round brings Spirit AI's total funding to approximately $420 million raised across funding rounds completed within a span of 30 days. This follows a February raise that valued the company at over 10 billion yuan - approximately $1.4 billion - making it a unicorn less than two years after its founding in January 2024.
What Spirit AI Is Building
Spirit AI is developing what it calls a "universal robotic brain" - a vision-language-action (VLA) foundation model that enables general-purpose robots to perceive, reason about, and act in real physical environments. The company's proprietary model drives Xiao Mo, a humanoid robot with 26 degrees of freedom built for industrial manipulation tasks.
The technology is not in testing - it is in production. Xiao Mo is deployed at CATL's Zhengzhou battery facility, handling over 1,000 battery cells per shift including complex flexible wire harness manipulation, with industry-leading precision and zero failures. A second robot, Mozi, operates in JD.com retail environments. Partners include Huawei, Xiaomi, and TCL.
The "Dirty Data" Thesis
Spirit AI's technical differentiation centers on what co-founder and chief scientist Gao Yang calls a "dirty data" strategy. While competitors rely on curated datasets or simulation environments, Spirit collects messy, unfiltered real-world interaction data captured via proprietary fifth-generation wearable devices. These devices reduce data acquisition costs by approximately 90% compared with traditional teleoperation-based collection. The company has accumulated over 200,000 hours of real-world robot interaction data and is targeting one million hours by end of 2026.
In January 2026, Spirit AI open-sourced its Spirit v1.5 model, which topped the RoboChallenge global leaderboard and reportedly outperformed Physical Intelligence's Pi0.5 on complex manipulation tasks. The zero-shot generalization capability - handling unfamiliar tasks without task-specific retraining - is the core commercial differentiator.
The Broader Context
Spirit AI is one of at least six Chinese robotics startups that raised over $100 million in February 2026 alone. Chinese government data shows embodied intelligence attracted more than 73.5 billion yuan across 740 deals throughout 2025. The investment coalition behind Spirit AI - spanning venture firms, state-backed funds from Chongqing and Hangzhou, and strategic corporate investors - reflects a coordinated national effort to establish Chinese leadership in physical AI. If large language models reshaped digital workflows, embodied AI is the category China is positioning to lead in the physical world.
