CEO, Goliath Artists Management
Eminem's manager spearheaded Activision deal and 2013's second-best-selling album
Paul Rosenberg -- the founder of Goliath Artists Management, whose clients include Eminem, Danny Brown and Action Bronson -- has learned to love saying "no."
"I've never felt bad about turning something down that wasn't right for my clients," Rosenberg says. "It's important to make sure you're doing the right deals, not just a lot of deals."
