Sabi raises $50M to build AI brain-reading baseball cap
AISabi has raised a $50M seed round led by Vinod Khosla and Accel to build a baseball cap that turns brain signals into AI prompts. The cap can hold up to 100,000 sensors of 1 to 5 millimeters each, feeding a brain foundation model trained on 100,000 hours of labeled neural recordings. Sabi says the cap can predict a user's next 3-4 keystrokes from brain signals before they type them.
