Bridge Neurotech launches with $13.5M for ultrasound brain interface

Bridge Neurotech has emerged from stealth with $13.5 million in funding, including from General Catalyst, to build a wearable ultrasound-based brain-computer interface rivaling Sam Altman-backed Merge Labs. The headphone-like device sits above the ear and reads brain activity via blood flow without surgery; its first observational clinical study has begun in Redwood City, California.
