REBECA LEÓN, 43
CEO, Lionfish Entertainment
48 MILLION MONTHLY LISTENERS FOR J BALVIN: In 2017, León left AEG/Goldenvoice after 11 years to focus on managing superstars Juanes and J Balvin. She got immediate results: In June, Balvin briefly became the most popular artist globally on Spotify -- the first Latin act to do so -- when he notched over 48 million monthly listeners. The Colombian star also renewed his multimillion-dollar global deal with Scotch whisky brand Buchanan’s. León, who sits on the Grammy Diversity Committee, also signed breakthrough flamenco revivalist Rosalía when she was an unknown. “She has taken off like nothing I’ve ever seen,” she says.
