Brain-computer interfaces

BCI companies compared

Seven companies are putting brain-computer interfaces into people. They differ in how deep the electrodes go, how many channels they read, and how close each device is to being sold. This table sets Neuralink beside Synchron, Paradromics, Precision Neuroscience, Blackrock Neurotech, Science Corporation, and China's Neuracle.

Figures as of October 7, 2026

How to read this

  • Channels counts the recording or stimulating sites on the main human device. Precision's films and Blackrock's arrays can be stacked, so one patient may get several.
  • Patients is the latest public figure and its date. Companies count in different ways: Precision counts procedures, many of them temporary, and Neuralink's figure is Neura Pod's count of publicly identified patients.
  • Funding shows total money raised or the latest valuation, whichever the company or reputable press has disclosed. Sorting by funding uses the largest disclosed dollar figure.
  • "Not disclosed" means no reputable public source gives the figure. Each cell links its sources.

Where Neuralink stands

Neuralink's N1 has the most channels of any fully implanted wireless device in this table, and its trials now run in 4 countries. Neuracle and Science Corporation are the first two companies here with a market approval, in China and Europe. Synchron, Paradromics, and Neuralink are still in feasibility studies in the United States.
