Chinese robotics startup Spirit AI raises $145m

Spirit AI, a Chinese robotics startup developing AI models for robots, said it raised 1 billion yuan (US$145 million) in a new funding round led by ShunWei Capital and YF Capital.

The funding comes weeks after two earlier rounds lifted its valuation above 10 billion yuan ($1.46 billion).

Fortune Capital, Galaxy Yuanhui Investment, Xin Ding Capital, and Glacier Capital also joined the round, among others, bringing Spirit AI’s total fundraising to nearly 3 billion yuan (US$438 million) across three rounds in about a month.

Founded in 2024, the company builds vision language action models for robots and open-sourced its Spirit v1.5 system in January, while the latest raise adds to a wider funding surge in China’s humanoid robotics sector despite unresolved commercialization challenges.

🧠 Food for thought

Implications, context, and why it matters.

Spirit AI’s funding is backed by real-world factory deployment

  • Spirit AI’s funding is new, yet its robots already run in tough industrial environments beyond lab tests 1.
  • At CATL, the world’s largest battery manufacturer, the “Moz” robot works on battery production lines, including high-voltage end-of-line testing such as inserting test plugs into battery packs 2.
  • Moz delivers a connection success rate above 99% and keeps pace with skilled human workers 2. Spirit AI also says its in-house robot “Xiaomo” runs at CATL’s Zhongzhou facility and supported fault-free mass production of nearly 1,000 battery cells 1.
  • Spirit AI says it has a strategic partnership with JD.com, one of China’s largest ecommerce companies. The Moz robot is part of JD MALL’s smart retail system for work such as automated coffee preparation, which supports live data collection and model improvement 1.

A strategic investor mix is fueling Spirit AI’s rise

  • Spirit AI’s funding comes from venture capital firms plus institutional investors, industrial companies, state-owned investors, and strategic investors 3.
  • Backers and shareholders include CATL and JD.com alongside financial investors. These relationships can open deployment sites and support data collection 43.
  • Work in partner facilities produces varied real-world data, often called “dirty data,” that the company uses to improve its AI models 3.
  • This blend of financial, industrial, state-backed, and strategic support aims to speed commercialization and make it harder for competitors to catch up 3.
