Working In Sync

Our name reflects our approach to the design process. We work with our clients to bring their vision, marketing objectives and technology requirements together to arrive at appropriate solutions.

Insync Design was formed in March 1994. Founding partners David Stowers and Mike Zambelli remain with the company, managing day-to-day operations of the business as well as being actively involved in design and program management. Our combined experience covers a very broad range of industries and product categories.  We are named as inventors on over 120 design and utility patents.

Our team of creative designers brings a wealth of experience and category expertise to every program. We know that it is critical to the success of a program to incorporate the ideas of our client into our design proposals as well as our own ideas.

Our client’s unique insight into their customer enhances our ability to provide creative solutions. We encourage participation from the internal team including, Engineering, Product management, Marketing and Sales. Often the best ideas come from a simple observation or thought.
