THE Sabi STORY

Non-Invasive BCI

Sabi makes a beanie that turns thoughts into text. Led by CEO Rahul Chhabra, the San Francisco company packs up to 100,000 sensors into a wearable cap that transcribes imagined thought.

Rahul Chhabra — Co-founder & CEO

Rahul previously worked as a researcher at Stanford University. He spent three years in stealth building a brain-computer interface that requires no surgery. An Ascend LP flagged Sabi's demo, and Ascend joined Vinod Khosla as the only other investor in the pre-seed."
