Thursday night Hinge celebrated the launch of its new app with a party at the 1776 Campus. With more than 1,900 RSVPs on the event’s Facebook page, this tech startup launch party was one you didn’t want to miss. The rager included an open bar featuring specialty cocktails from Tito’s vodka, Catoctin Creek whiskey, and Green Hat gin, plus beer, wine, and bubbly; complimentary snacks from PopChips; and beats from deejays Ricky Schramm and Viceroy. Hinge is a dating app that lets you rate friends of friends and connect when there’s mutual attraction.
