PHIL MCINTYRE, 33
Last Year's Rank: —
McIntyre brought clients the Jonas Brothers to stadiums and Demi Lovato to arenas. Then he saw the former break up and the latter check in to rehab. His faith that the talent he had nurtured would mature paid off in 2015: Nick Jonas and Lovato sold 2.9 million and 2.2 million digital tracks, respectively, and wowed with 274.1 million and 475.6 million programmed and on-demand streams. Roc Nation invested in PhilyMack and, in a joint venture with Island Records, McIntyre, Jonas and Lovato started the label SafeHouse.
