BrainCo is China's leading non-invasive BCI company, incubated at the Harvard Innovation Lab and founded by Han Bicheng during his PhD at the Harvard Center for Brain Science. The company develops BCI-controlled bionic prosthetics and cognitive training devices. BrainCo completed a CNY 2B ($286M) financing round in 2025, the largest BCI funding globally outside of Neuralink. The company is preparing for a potential IPO in Hong Kong or mainland China at a $1.3B+ valuation. BrainCo's bionic hands enable amputees to write, type, and perform complex tasks using non-invasive neural signal interpretation. The company also operates BrainRobotics, its prosthetics subsidiary.
