Mr. Toma has been going to parties for most of his life. As a teenager in the late 1990s, he held hip-hop parties while attending Xaverian High School in Brooklyn. During his senior year, he visited the Sound Factory, an iconic megaclub on the West Side of Manhattan, and began his journey into dance music.

His parents, who immigrated from Egypt, saw him as a potential doctor or lawyer, and he attended two years of college at St. John’s University’s Staten Island campus. “But I found myself promoting, networking, brokering frat parties,” he said. That path led to jobs at clubs like Exit, Spirit, Crobar and Pacha, as well as six consecutive seasons in Ibiza.

“Rob is extremely well networked and plugged in on an international scale,” said Michael Delle Donne of Resident Advisor, an electronic music platform that frequently sells tickets to Teksupport events. “He really lives behind the scenes, behind the curtains and out of the spotlight. He’ll be in the greenroom working on a computer while the event is raging.”

Unlike the dance clubs he grew up with in the 1990s, which came under siege by former Mayor Rudolph Giuliani, Teksupport has a cozier relationship with city officials. Its breakthrough event — importing Time Warp, a German electronic music festival, to Brooklyn in 2014 — took place on the city-owned South Brooklyn Marine Terminal in Sunset Park. Mr. Toma credits relationships with community boards and Mayor Bill de Blasio’s Office of Nightlife.

“It’s like, whoa, they finally woke up and smelled the coffee,” Mr. Toma said. “There’s a lot of up-and-coming politicians coming in. They just get it — they went to their Coachella.”
