7. Robot Leasing Startup “Tianzhu Leasing” Becomes Unicorn

  • 凤凰网 · 2026-05-24
  • Summary: Robot leasing startup Tianzhu Leasing has completed Series A and A+ rounds totaling hundreds of millions of yuan, pushing its valuation to 7 billion yuan (~$1 billion), making it a unicorn. The company provides direct leasing and solution-based leasing for robots, initially focusing on display and event scenarios but now pivoting to industrial applications like manufacturing and warehousing.
  • Why It Matters: The emergence of a leasing unicorn indicates a key bottleneck in robotics adoption: high upfront CapEx. This validates the business model of Robotics-as-a-Service (RaaS), which lowers the barrier to entry for enterprises, accelerates deployment cycles, and shifts the competitive focus from hardware specs to long-term service and reliability.
