Stedi™ was founded by Matt Cumella, a Boston area Doctor of Physical Therapy board certified in Geriatrics. Matt has spent years focused on helping older adults stay upright and independent. He has experienced countless scenarios with patients where the capability of their assistive device felt like the missing link between them and their mobility goals. Leveraging these experiences and a deep understanding of the way we move, he began devising devices to support more optimal mobility through injury, illness, and chronic condition. Soon thereafter, Stedi and the Reaction Stabilizer were born.

We're excited to be developing a capable team and valuable partnerships in our dedication to building a new generation of mobility devices. We're taking a modern & scientific approach focused on circumstances of needs and addressing the core challenges faced by users, families and medical professionals.

We are a proud member of MATTER, the premier healthcare incubator and innovation hub, including hundreds of cutting-edge startups from around the world, working together with dozens of hospitals and health systems, universities and industry-leading companies to build the future of healthcare. Together, the MATTER community is accelerating innovation, advancing care and improving lives. For more information, visit and follow @MATTERhealth.
