Sabi raised a $50M seed round led by Khosla Ventures, with Accel and DST Global participating, to develop an EEG-equipped cap for decoding imagined speech. The company claims it built a foundation model trained on over 100,000 hours of recordings and that it now reaches 30 words per minute at up to 77% accuracy using a wired lab prototype. No peer-reviewed results or accuracy methodology have been published. An early wearable prototype is expected at CES 2027.
