EngineAI

EngineAI is a Chinese humanoid startup focused on locomotion speed as its primary performance differentiator, with the T800 targeting 3+ m/s bipedal walking — the fastest in its class. The company raised $139M in its Series A1 from JD.com in July 2025, reflecting JD's strategic interest in fast-moving robots for its logistics and fulfillment operations. Dual battery options (ternary lithium or solid-state) cater to different deployment environments.
