Dave Grutman, Miami Marketing Group, Founder
This self-made megaclub kingpin crawled his way up the nightlife ranks, starting as a South Beach bartender and eventually winding up as head of Miami Marketing Group, operators of superclub LIV. If anything signifies the big-money, mainstream breakthrough of dance-music, it's this two-story cavern in the glitzy Fontainebleau Hotel. Think Ibiza-style go-go dancers/contortionists, ticker tape explosions, and a parade of sparkler-topped liquor bottles. Playing here is a rite of passage for any breakthrough EDM star – LIV raked in more than $40 million in 2014, according to Nightclub & Bar magazine's annual Top 100.
