Open Bionics

Open Bionics operates at the intersection of medical devices, robotics, 3D printing and social-impact healthcare. Its core differentiation is an attempt to make upper-limb prosthetics more accessible through lightweight, 3D-printed designs, configurable aesthetics and a portfolio spanning everyday, rugged, activity and partial-hand use cases. The Hero Arm combines myoelectric control with multiple grips, interchangeable covers and an adjustable, ventilated socket, while the broader ecosystem includes MyoPods, the Sidekick App and Activity Attachments. In the wider prosthetics market, Open Bionics competes for clinical attention and patient budgets with established manufacturers such as Ottobock and Össur, which have broader global distribution and mature clinical networks. Open Bionics appears more narrowly focused on upper-limb devices and differentiates through consumer-oriented customization, licensed character designs and product variants such as Hero RGD and Hero FLEX. Its 2024 funding total of $15.7 million is modest relative to large incumbent medtech businesses, suggesting a focused challenger profile rather than a full-line prosthetics platform.

Open Bionics shows a trajectory from early grants and seed financing toward larger equity, venture and debt-backed commercialization. The company received a $1.0 million grant in February 2017, followed by an undisclosed venture round, non-equity assistance and a $943,155 grant later that year. A £435,000 seed round in January 2018 preceded a £4.645 million Series A in January 2019, equivalent to $5.925 million in the financial record. Funding activity accelerated again in 2022 with a $3.217 million venture round and $1.846 million equity crowdfunding round, then continued with $764,202 of debt financing in November 2024. Product breadth has expanded beyond the original Hero Arm to Hero PRO, Hero RGD, Hero FLEX, Hero Gauntlet and MyoPods. The 2025 Hero RGD launch marked an inflection point toward rugged and activity-specific applications, including a first U.S. veteran fitting. Hiring growth, revenue growth and production scale remain undisclosed.
