About BionicM

BionicM Inc. is a developer of powered prosthetic solutions for lower-limb amputees, founded in 2018 as a spin-off from the University of Tokyo. The company's creation stems from the doctoral research of its founder and CEO, Dr. Sun Xiaojun, who is himself an amputee. Sun lost his right leg to bone cancer at age nine and used crutches for 15 years before getting his first prosthesis, an experience that drove him to develop better solutions. After earning a master's degree and working as an engineer at Sony, he pursued a Ph.D. at the University of Tokyo, focusing on robotic prosthetic legs, which led to the founding of BionicM.

The company's main business is the research, development, and commercialization of robotic prostheses. Its flagship product, the Bio Leg®, is a powered prosthetic knee that utilizes robotics and AI to replicate lost muscle strength, assisting with movements like walking and ascending stairs. This technology is designed to reduce the physical burden on users, enabling more natural and intuitive movement. The Bio Leg®, which weighs about six pounds and has a full-day battery life, has received FDA Class II registration and U.S. medical insurance coverage. The company is also developing a more affordable model, the Cybo Leg, and exploring features to collect biometric data to help clinicians guide gait training.

BionicM operates on a business model that involves partnering with third-party socket manufacturers, which helps make its products more affordable than some competing devices. The company launched sales in China and Japan in 2021 and entered the U.S. market, the world's largest for prosthetics, in August 2024. To support its global expansion, BionicM established a U.S. subsidiary in Virginia and has raised approximately $12.7 million in total funding from investors including UTEC, JST, and Shinsei Corporate Investment.
