Sabi raises $50 million to build a brain-AI interface cap

Sabi announced a $50 million seed round led by Khosla Ventures to develop a baseball cap containing an EEG interface for future AI control. It says sensors are designed to read electrical activity through hair without surgical implantation.

The company describes a proprietary neural dataset and internal hardware tests, but the ability to reliably decode imagined words or commands outside the lab has not been independently established. The prototype is planned for demonstration in 2027.
