Simplify's Take

What believers are saying

  • Nudge said in March 2026 it uses the device on people nearly daily.
  • Hiring stayed active in July 2026, with software, firmware, and research roles open.
  • The $100 million Series A funds aggressive testing, manufacturing, and regulatory preparation through 2027.

What critics are saying

  • Nudge Zero is not portable, blocking consumer adoption and prolonging expensive clinical workflows.
  • FDA clearance for ultrasound brain stimulation remains unproven; one adverse event can freeze commercialization.
  • Neuralink, Kernel, and academic ultrasound labs can outspend Nudge before 2027.

What makes Nudge unique

  • Nudge Zero uses focused ultrasound to stimulate and image the brain with millimeter precision.
  • Nudge’s helmeted phased-array architecture runs in MRI, enabling whole-brain research-grade mapping.
  • Fred Ehrsam’s Nudge raised $100 million from Thrive Capital and Greenoaks in 2025.
