829,000 SIMULTANEOUS YOUTUBE STREAMS: Pop's highest-profile millennial manager wrapped 2018 by securing Ariana Grande top billing for Coachella 2019, after her surprise single "Thank U, Next" smashed streaming records on Spotify and YouTube, where 829,000 fans simultaneously viewed the song's official video premiere. Meanwhile, SB Projects celebrated the crossover success of country-pop duo Dan + Shay, whose single "Tequila" shot to No. 21 on the Hot 100. (SB Projects co-manages the duo with Jason Owen.) Braun also waded deeper into waters of film and TV, launching Mythos Studios, a joint venture with Marvel Studios founding chairman David Maisel, and GoodStory Entertainment, an unscripted-content studio with veteran reality producer JD Roth. "Every business is a microcosm of another business," says Braun, a father of three who's also producing an FX series starring white-rap jokester Lil Dicky.
