Headliner.fm is about letting bands reach fans. Headliner is growing fast, in January the bands on Headliner had less than one million fans. Now, bands using Headliner have a combined fan base of over 16million. So how has using Headliner benefited those bands? In the first 15 days of March bands used Headliner to promote themselves to 9 Million new fans. That means more people than there are living in New York City saw a message sent by Headliner in the last 15 days. Pretty crazy.
