Daniel Hermann and his buddy Sean McGrail loved going out to bars after work--and decided to add paint and a canvas to the experience. Using a licensing model, the company works with more than 250 "creative entrepreneurs" who book local artists to host painting events at bars and nightclubs across the United States. Today, more than 200,000 individuals participate in a Paint Nite event every month. With Hermann as chief executive, the Somerville-Massachusetts-based company has grown more than 36,555 percent over the past three years to $55 million, earning it the No. 2 spot on the 2016 Inc. 5000 list.
