Mark Williamson joined Spotify in 2011 and helped start -- and then ran -- the artist relations team there for almost a decade. He likes to joke that he spent that first five years at Spotify getting shouted at about streaming economics and then the next few years getting shouted at when artists didn't get on the New Music Friday playlist. He wishes that was just a joke.

After leaving Spotify, Mark founded ROSTR, a startup building technology to help create a fairer and more connected music industry. ROSTR tracks hundreds of thousands of relationships across the music industry in an effort to make it easier to navigate.

Mark currently lives in Baja, Mexico, with his wife and two boys.
