Tom Monaghan

Delivery franchising. Monaghan bought a small pizza shop in Ypsilanti, Michigan, with his brother in 1960 and built Domino's around one promise, fast delivery, with a narrow menu and simple kitchens that franchisees could run near student and military towns. Its 30-minute guarantee was dropped in 1993 after lawsuits over crashes involving delivery drivers. He sold the company in 1998 and turned to Catholic causes.
