Products on sale: prosthetic hands controlled by muscle signals, and EEG headbands. It has no implanted work.

Still an aim

A public listing. A confidential Hong Kong filing was reported in January 2026.

What stands in the way

Signal: muscle and scalp recordings carry far less information than an implant, which bounds what the products can do.

BrainCo is the largest capital story in neural interfaces outside the United States, and it is a non-invasive one. Its bionic hands read muscle, not brain, and its EEG products make modest claims. That is the point: it is the clearest test of whether neural-interface technology can be a consumer and assistive-device business at scale before any implant is.
