Synchron, a New York, NY-based manufacturer of non-surgical brain-computer interface technology, said it has raised a $200 million series D round. The funds are expected to accelerate commercialization of the company’s first-generation Stentrode BCI platform, while advancing development of a frontier next-generation interface.
The financing brings Synchron’s total funding to $345 million.
Double Point Ventures led the round, alongside existing investors ARCH Ventures, Khosla Ventures, Bezos Expeditions, NTI and METIS. New investors include the Australian National Reconstruction Fund (NRF), T.Rx Capital, Qatar Investment Authority (QIA), K5 Global, Protocol Labs, and IQT.
Synchron said its Stentrode BCI platform is the first endovascular brain-computer interface, designed to translate brain activity into digital commands without open-brain surgery. Placed via a non-surgical catheter procedure, the Stentrode interfaces with the motor cortex through the blood vessels, recording and transmitting neural signals wirelessly to enable hands-free control of digital devices. Stentrode BCIs have been placed in 10 patients with paralysis to date, across clinical trials in the United States and Australia.
Synchron has integrated Apple’s BCI-human interface device (BCI-HID), having co-developed a Bluetooth-based iOS protocol that connects brain activity directly to Apple devices using Switch Control, including iPad, iPhone, and Vision Pro — no touch, voice, or eye-tracking required.
“We’ve built the first non-surgical brain-computer interface designed for everyday life for people with paralysis,” said Synchron Founder and CEO Tom Oxley. “This funding brings us closer to commercializing the Stentrode BCI platform, while accelerating development of a major breakthrough in the field — a next-generation, transcatheter high-channel whole-brain interface.”
An expanding Cognitive AI division in New York, NY will be training models that learn from brain data to decode thought in real time. In parallel, a new San Diego, CA-based engineering hub has been established to build the brain interface.
“Synchron is building the first truly scalable, minimally invasive brain-computer interface that can be deployed in everyday healthcare,” said Campbell Murray, MD, co-founder and managing partner at Double Point Ventures. “Its fusion of neurovascular access, breakthrough device engineering, and adaptive AI marks a fundamental step toward restoring digital agency to people with paralysis.”
With this series D financing, Synchron said it will accelerate pivotal trials, prepare for commercial launch of the Stentrode BCI system, and continue hiring engineers, neuroscientists, and operators to advance the next generation of brain-computer interfaces.
