Cousins Maine Lobster has experienced consistent growth since its launch in 2012, buoyed by an early investment from Shark Tank judge Barbara Corcoran, but the pace of that growth has since accelerated. The concept, founded by cousins Sabin Lomac and Jim Tselikis, who spent their summers in Maine while growing up, now counts 66 trucks throughout the country and five brick and mortar locations. Last week, the company made its debut in the Louisville, Ky., market with a truck that will rotate between the city, as well as Lexington, Ky., and just across the Ohio River to Evansville, Ind.
