JONATHAN HULL, 36
Head of Music Partnerships, Facebook
Last Year's Rank: —
No person reaches more music fans than Hull. The father of three and hobbyist musician -- he plays and records with the band Jones Street Station -- splits his time educating the product team about the music industry while helping artists, managers and labels get the most out of Facebook, where more than 780 million connect to at least one artist, and Instagram, where six of the top 10 accounts are musicians.
