This Cap Reads Your Brain - Sabi Launches a Wearable BCI Backed by Khosla and OpenAI's CPO

Sabi has launched a wearable brain-computer interface that fits inside a standard cap, marking a significant shift towards accessible neural control technology. The startup claims users can type and click using only their thoughts, eliminating the need for traditional input devices. Unlike Neuralink's invasive approach requiring surgical implants, Sabi's solution is entirely non-invasive. The company has secured backing from prominent investors including Khosla Ventures, Accel, Initialized Capital, and notably Kevin Weil, OpenAI's Chief Product Officer. This investor lineup suggests confidence in the technology's commercial viability and strategic importance in the AI ecosystem. Sabi's technical approach centres on what they describe as the world's largest neural dataset, which has been used to train their "Brain Foundation Model." The system relies on custom application-specific integrated circuits (ASICs) designed specifically for reading brain signals through wearable hardware. These purpose-built chips represent a departure from general-purpose processors typically used in brain-computer interface research. The non-invasive nature of Sabi's technology could dramatically expand the potential user base for brain-computer interfaces. By removing surgical barriers and offering a familiar form factor, the company positions neural control as a mainstream computing interface rather than a medical intervention. The backing from established AI investors suggests this technology may integrate with existing AI systems to create more intuitive human-computer interactions.
