Your tech solution to motor rehabilitation.

Our Device

Waiv is a brain-computer interface (BCI) specialized to provide motor rehabilitation for victims of stroke. It is a two-part device – a headset for brain signal monitoring and an arm cuff for functional electrical stimulation (FES). The two parts work in conjunction to capitalize on the regenerative capacity of our brains by utilizing a technique named Hebbian Learning.

Functional Electrical Stimulator



Waiv uses BlueTooth technology to remove wires and improve mobility. No longer are patients restrained to a bed, chair, or computer; instead, they are free to relocate to their place of comfort.


Our software WaivTrain guides users through a calming training routine. Conventional BCI training can be taxing, so we aim to make it as simple for the user as possible.


Custom hardware design dramatically drives down the cost of the device. This makes the product competitive for insurance coverage.

Stroke victims usually require some degree of assistance from a caretaker. Surveys show that over 40% of stroke patients are extremely dependent on a caretakers assistance. Similarly, over 58% of stroke patients feel ends up plateauing and does not improve further. Over 64% of survey respondents feel there are not enough options for them to receive adequate treatment. At Waiv, we are committed to expanding rehabilitation options for patients in need and improving their autonomy so that they can get their previous lifestyle back.


BCI technology is a growing market, as such there are many companies developing solutions using this brain monitoring technology. Some companies will be analyzed below. Waiv provides a solution specifically for stroke motor rehabilitation

Stroke Rehab Market

The stroke rehabilitation market has grown considerably over the past 10 years and is expected to grow by 2050. On average, stroke patients currently pay approximately $140,000 in rehabilitation costs throughout their lifetime. The current market is worth $45.5 billion in US expenditures. If our device reaches 5% of annual stroke patients, our expected share of the market would be worth about $80 million annually.
