Precision Neuroscience closes a $250M Series D for its thin-film BCI

Precision Neuroscience closed a $250 million Series D on 24 September 2026. Pershing Square, the Ackman Oxman Institute and an unnamed life sciences investment fund led the round, which brings the company’s total funding to $430 million since its founding in 2021. Duquesne Family Office, B Capital, ARK Invest, Invus, Mubadala Capital, Mirae Asset Capital, Korea Investment Partners, Hitachi Ventures and JSL Health Capital also took part.

The company builds the Layer 7 Cortical Interface, a thin-film electrode array that rests on the surface of the brain instead of penetrating the tissue. Layer 7 has already received FDA clearance, and Precision says it has now been used in more than 100 procedures at 18 medical institutions, among them the Perelman School of Medicine at the University of Pennsylvania, University of Chicago Medicine, Mount Sinai Health System and West Virginia University’s Rockefeller Neuroscience Institute.

Precision says the money will expand its clinical program, carry Layer 7 through the next stages of FDA review and build the infrastructure needed to bring the device to market.
