Cohen is starting 300 with his fellow ex-Warner Music colleagues Todd Moscowitz (ex-Warner Bros president) and Kevin Liles (ex-EVP Warner Music). All three had also worked together at Def Jam, which Cohen ran in the '80s and '90s.....The company is getting backing from a wide range of investors, led by Google, which has put in around $5 million, according to one person familiar with the terms.....Another key investor was investment firm Columbus Nova, which recently took a significant stake in digital music service Rhapsody. He’s also being backed by Israeli-American hedge fund billionaire Noam Gottesman’s Toms Capital, whose offices Cohen has been working from since soon after he left Warner Music (the company is currently seeking their first formal office). Former Warner Music digital chief Alex Zubillaga (and in-law of Edgar Bronfman Jr.) is another backer. Zubillaga has a track record of digital investments including FanBridge and Chartbeat. One other investor is Andres Santo Domingo, co-founder of Brooklyn-based Kemado Records and a son of one of Colombia’s richest families. There are other investors who have declined to be identified. The investment agreements were pulled together by veteran media investment banker Aryeh Bourkoff and Ori Winitzer of LionTree.
