Sabi Raises $50M for Wearable BCI Beanie That Decodes Thoughts Without Surgery

Palo Alto startup Sabi has secured a $50 million funding round led by Khosla Ventures, Accel, and Initialized Capital to develop a wearable brain-computer interface. Rather than requiring surgical implants like Neuralink, the company's flagship device is a beanie embedded with 70,000 to 100,000 miniature EEG sensors designed to read electrical activity from outside the skull. Sabi claims the hardware will decode internal thoughts into digital text at an estimated speed of 30 words per minute. The new capital is earmarked for hardware improvements and the development of a proprietary "Brain Foundation Model" trained on approximately 100,000 hours of neural data to filter external signal noise. The startup aims to ship the consumer wearable by the end of 2026, positioning the sensor-dense fabric as a non-invasive, consumer-friendly alternative to surgical brain implants.
