DETROIT – When two Metro Detroit natives wanted to start their own business, they drew inspiration from the Motor City. It started when four friends thought they could improve a car air freshener into something more cool. Donovan Brown and Garrick Mitchell both graduated from west Bloomfield High School in 2007. “We’ve all been either starting or attempting to start businesses literally since high school,” Brown said. “We’ve been around for about two and a half years now amd have over 10,000 active subscribers,” Mitchell said.
