Established in April of 2005, Keystone Design, Inc. was a machine design company that had one client that supplied assembly equipment for the Automotive Interior Industry. In 2006 we transitioned from a 2D to a 3D design company using SolidWorks as our design tool. We quickly developed modeling procedures for our designs which allowed us to have multiple designers work on the same projects without the headaches of dealing with individual designer modeling techniques. Prior to the 2008 collapse of the automotive industry we reached out and obtained new clients in the Appliance, Medical and Defense Industries. Because of our diversification and use of modern day internet tools we were able to achieve steady growth though out the United States.
