Bridge Neurotech launches ultrasound-based brain-computer interface with $13.5 million backing
Bridge Neurotech announced its debut, aiming to create a wearable ultrasound brain-computer interface and has secured $13.5 million in funding.
Will Biederman, former Neuralink chip developer, founded Bridge Neurotech to pursue a non-invasive brain-computer interface that uses high-frequency sound waves instead of surgical implants. Backed by $13.5 million from General Catalyst and additional investors, the startup aims to deliver a wearable device resembling headphones that can capture neural activity through the temporal window of the skull. An initial observational study will be run in Redwood City, California, placing a small ultrasound probe on participants’ heads to record brain signals during various tasks.
Bridge plans to mitigate the several-second lag of blood-flow-based measurements with predictive AI models. The effort joins a crowded field that includes Neuralink, Synchron, Paradromics, and Precision Neuroscience, but differentiates itself by targeting both medical and consumer markets without surgery.
Why it matters
A non-invasive brain-computer interface could broaden access to neurotechnology for medical and everyday uses.
