A student promoter from Thunder Bay helped turn the concert into a global business. Twenty-one years into running Live Nation, Michael Rapino is confronting the consequences of bringing so much of the show under one roof.

Ari Daie is the founder, CEO and president of FEVO, a New York social-commerce platform that turns the lonely online checkout into a group activity. After a career that ran through Goldman Sachs, two startups he built and sold, and a senior dealmaking seat at Ticketmaster/Live Nation, Daie built FEVO on a simple bet: people would rather buy tickets and merchandise together than alone. The platform now powers more than 750 partners across the NBA, NFL, MLB, NHL, MLS and Formula 1, and FEVO has reported scaling past a billion dollars in sales while raising tens of millions in venture funding.
