GUIwerks

GUIwerks is a product design firm specializing in the creation of Graphic User Interfaces for mobile. Put simply, it is about building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. They are a small team, 11 to 50 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

GUIwerks is based in Philadelphia, Pennsylvania. More on guiwerks.com.
