Matt Maloney

CEO, GrubHub Seamless

Online food delivery competitors GrubHub and Seamless merged in May, with Maloney at the helm. Seamless owned the New York City food delivery market while GrubHub made waves in the Midwest. Combined, the two companies reach 500 cities and work with more than 20,000 restaurants.

Previously, Maloney led GrubHub through five rounds of funding, totaling $84.1 million.

This month, GrubHub Seamless announced plans to file for an IPO in 2014. It should help it fend off Yelp, which recently entered the food delivery business.
