Bridge Neurotech non-invasive fUSI BCI
Bridge Neurotech (Redwood City, founded 2026) is building a fully non-invasive BCI: functional ultrasound imaging (fUSI) of brain activity through the skull, decoded with AI models. The company emerged from stealth on Oct 6, 2026 with a $13.5M raise and a research and development agreement with Butterfly Network, licensing Butterfly’s Ultrasound-on-Chip technology; the agreement includes commitments to purchase Butterfly hardware.

Notes
- Founder Will Biederman previously co-founded Forest Neurotech - since renamed Arbor Neuroscience per the organization’s own site (forestneurotech.org, verified 2026-10-23) - where he led development of a miniaturized fUSI device used to image the human brain (his own account) [1].
