It’s networking on performance-enhancing drugs. Actually, a performance-enhancing app. On June 4, Long Island City-based tech startup herematch will use its namesake app to host a Matchup on the Z Hotel’s rooftop in LIC (above photo depicts herematch owners at similar event). Roughly 200 attendees are expected, and they will use the free herematch app on smartphones to learn about other attendees with complementing talents, similar professional or personal interests and the same memberships, alma maters or even hometowns. Details: Matchup, June 4, Z Rooftop, 11-01 43rd Avenue, LIC, Free with complimentary hors d’oeuvres and a cash bar featuring Z’s signature Bridgeview cocktail (below), register here.
