Ash Pournouri, At Night Management, founder
"We don't discover artists. We create them." That's mighty tall talk to put on the homepage of a music-management website, but it's fully justified by At Night leader Ash Pournouri's track record. Pournouri is the man behind Swedish dance-pop idol Avicii and dubstep duo Cazzette, and he's implemented a strategy based on networking, marketing, and musical savvy – he works closely with Avicii in the studio, as well as in the boardroom. Pournouri got his prize client an opening slot with Madonna (the two are now collaborating on her next album), launched his single "Wake Me Up" to Number 1 in 22 countries, and transformed Avicii from track-maker to pop star inside seven years.
