revolutionizing access to prosthetic care with a simple solution

Fitting Carlos with the OpenSocket

We discover big problems, rethink them, and develop solutions which help overcome them.

Design Studio

Bump is a 501(c)(3) nonprofit design studio that embraces difficult problems and subsequently creates products which are desperately needed in the nonprofit ecosystem. 

The OpenSocket

The OpenSocket prosthetic arm has been in R&D since 2009. After hundreds of iterations working closely with users, we launched the OpenSocket with local partners in Central America in Jan 2013. 

Our Passion

It's not about creating things. It's about a never ending passion to understand humans, the problems they face, and how the right solution can help them to overcome.
