Ray Kurzweil joins Subsense’s push for a brain interface delivered through the nose

Ray Kurzweil joins Subsense as an advisor as it pursues a nasal nanoparticle brain interface, with human safety and reliable function still to be proven.

Ray Kurzweil is joining neurotech startup Subsense as a product and vision advisor as the company develops an experimental brain interface that would deliver nanoparticles through the nose. The proposed system pairs those particles with an external wearable to read neural activity and stimulate neurons while potentially avoiding electrode implantation.

As reported in The Rundown’s September 4 newsletter , Subsense remained preclinical, had raised $27 million, and was targeting clinical pilots in 2027–29. Kurzweil’s appointment brings a prominent AI futurist to the project, but the central question remains whether the technology can work safely and reliably in people.
