New funding to advance non-surgical brain interface technology and expand clinical and engineering capabilities globally
Synchron, a leading brain-computer interface (BCI) company, has raised $200 million in a Series D funding round to accelerate the commercial rollout of its Stentrode BCI platform and advance the development of next-generation neural interface technologies.
The investment round was led by Double Point Ventures, with continued participation from ARCH Ventures, Bezos Expeditions, Khosla Ventures, METIS, and NTI. New investors joining this round include the Australian National Reconstruction Fund (NRF), Qatar Investment Authority (QIA), T.Rx Capital, K5 Global, IQT, and Protocol Labs.
Synchron plans to leverage the new capital to expand clinical studies, scale its workforce across scientific, engineering, and commercial functions, and advance product development toward full commercial readiness.
“We’ve built the first non-surgical brain-computer interface designed for everyday use by people with paralysis,” said Tom Oxley, Founder and CEO of Synchron. “This funding brings us closer to commercializing the Stentrode BCI platform while accelerating work on a major breakthrough — a next-generation, transcatheter, high-channel, whole-brain interface.”
The Stentrode platform converts neural activity into digital commands, allowing users to control external devices without physical movement. Unlike traditional brain implants, it is inserted via a minimally invasive catheter and interfaces with the motor cortex through blood vessels, eliminating the need for open-brain surgery. Once implanted, the device wirelessly transmits brain signals, enabling seamless interaction with digital devices.
To date, ten individuals with paralysis have received the Stentrode implant as part of ongoing clinical trials in the United States and Australia.
Synchron has also integrated Apple’s human interface technology, co-developing a Bluetooth-based iOS protocol that connects brain activity directly to Apple devices, including iPhone, iPad, and Vision Pro, through the Switch Control feature—bypassing the need for voice, touch, or eye-tracking input.
The company’s Cognitive AI division in New York is developing advanced algorithms to decode neural data in real time, while a newly established engineering centre in San Diego will focus on designing and building next-generation brain interfaces.
With this latest funding, Synchron is poised to accelerate its mission to empower individuals with paralysis and redefine how humans interact with technology through thought alone.
