Having sales experience, Mark Walker and Dr. Rusty Bishop (co-founders of Red Funnel which developed FatStax) both realized that sales reps in the field were at a distinct disadvantage. Technology had given the potential customer more knowledge about a given product or service than what the sales professional was prepared for in their meetings, especially when responsible for a complex and extensive product line. Mark and Rusty came together and created the FatStax Mobile Platform.
