Sabi's Wearable Brain-AI Bet Opens With a $50M Seed Led by Khosla Ventures
The San Francisco company's $50M seed also drew Accel, Initialized Capital, DST Global, Collaborative Fund, Ascend and former OpenAI chief product officer Kevin Weil.
Sabi, a San Francisco-based company developing a brain-AI interface designed for everyday wear, has raised a $50 million seed round led by Khosla Ventures.
The round was announced on October 9, 2026, and the syndicate extended well beyond the lead. Accel, Initialized Capital, DST Global, Collaborative Fund and Ascend all participated, alongside Kevin Weil, the former chief product officer at OpenAI.
Sabi's stated purpose for the $50 million is the development of its brain-AI interface, which the company describes as designed for everyday wear. The company has not said how the seed capital will be divided across research, engineering or hiring, nor has it put a timeline on the work. The announcement describes the product as a brain-AI interface designed for everyday wear; no further product specifications, launch date or pricing were disclosed.
What the round does show is the shape of the investor group behind the concept: a lead in Khosla Ventures, a bench of established venture firms in Accel, Initialized Capital, DST Global, Collaborative Fund and Ascend, and a single named angel in Weil, a senior product executive who previously worked at OpenAI. That mix of institutional capital and an operator with large-scale AI product experience backs a company still at the seed stage.
Sabi is based in San Francisco, CA.
