- Next-Generation Design: OAK was developed with leading design teams and offers enhanced cognitive and mental health benefits.
OAK is a next-generation wearable device designed to treat mental health conditions such as depression and anxiety through brain stimulation. Developed by Fisher Wallace, OAK builds on 15 years of research and the success of its Version 1.0 device, which sold 100,000 units and generated $40 million in revenue under temporary FDA clearance. OAK’s technology has been modeled by Massachusetts General Hospital and Harvard Medical School, demonstrating engagement with critical brain structures associated with mood, sleep, and cognition. The company is pursuing FDA clearance for anxiety treatment with an anticipated submission by April and plans for future regulatory approvals in both the U.S. and Europe.
The funds raised through this convertible note offering will be used to support OAK’s FDA clearance applications, expand clinical trials, and prepare for commercial release. The company aims to market OAK not only as a medical device but also as a wellness tool that appeals to a broader consumer base interested in cognitive enhancement and mental well-being. Strategic partnerships, including one with BlueIO for venture financing, and advisory support from Dr. David Shulkin, former US Secretary of Veterans Affairs, position Fisher Wallace to scale OAK’s impact, particularly among veterans and first responders. With an established market presence and strong clinical results, OAK is on track for a 2025 launch in the U.S.
