Sabi raises $50 million for a thought-reading brain cap

This is a big deal. Sabi just raised $50M to build a brain-AI interface you wear as a cap, outfitted with 100,000 sensors, that will enable people to talk to their AI agents just by thinking. I did some BCI research during my PhD, but the tech wasn't that great. It's great to see investment in improving the hardware, since current AI can unlock interesting research and personal agentic applications.

Brain foundation models after reading my thoughts. These guys just raised $50M to build their own chips for a cap that turns your thoughts into prompts.

Neuralink founders must be SHAKING right now... these guys just raised $50M to build a baseball cap that reads your mind: you put it on, you think, and it types for you... no keyboard, no talking with Neuralink, step one is brain surgery but these guys built a chip that reads your brain from the outside, without even touching your skin, small enough to fit inside a cap and they didn't borrow anyone's tech... they designed the chip, built the sensors and trained their own AI on brain data it can already guess the next 3-4 keys you're about to hit, before your fingers move insane times we're living in

Sabi is building a baseball cap that turns thoughts into prompts for AI agents. An early wired helmet version hit up to 77% accuracy in the lab, the company says. That error rate would sink a keyboard. An AI agent might live with it. Brain-computer interfaces were built for a harder job. Neuralink, valued at $42 billion, implants chips so people with paralysis can control a computer by thinking. Precision like that has mostly meant hardware inside the skull. Khosla, who led the round, put the scale problem bluntly to Forbes. “You’re not going to do a billion brain surgeries.” A cap trades surgery for a weaker signal. A University of Chicago neurology professor told Forbes that signals filtered through skull and scalp come out lower quality. An agent asks for much less. Sabi’s pitch is…
