With the Slice app, local pizzerias get a bigger piece of the market

Although Ilir Sela spent much of his childhood hanging out in his friends’ and family’s pizzerias, he didn’t follow his father and grandfather in pursuing a career tossing dough and ladling red sauce. Instead, in 2003, a year after graduating from the College of Staten Island, Mr. Sela founded Nerd Force, a tech support company. Over the subsequent decade, however, he saw online ordering increase in popularity via platforms like UberEats and GrubHub, which merged with the online food ordering platform Seamless in 2013 .
