Brain-computer interface startup co-founded by Sam Altman, Alex Blania, Sandro Herbig and researchers Tyson Aflalo, Sumner Norman and Mikhail Shapiro. It is developing less invasive neural interfaces built on ultrasound and molecular approaches instead of implanted electrodes. It raised a $252M seed round in January 2026 and licensed Butterfly Network's ultrasound-on-chip technology in September 2026.
