About ROSTR

The ROSTR Group is a media and technology company based in Los Angeles, founded in 2018 by Mark Williamson and Adam Watson, both former Spotify executives.

While at Spotify, Mark and Adam saw firsthand how fragmented the music industry had become. Something as basic as finding out who managed an artist was way harder than it should have been. And with the industry going more global every year, that problem was only getting worse.

They founded The ROSTR Group to build modern infrastructure for the music business. The company's flagship product, ROSTR, is a data and intelligence platform used by music professionals across labels, agencies, management companies, and distributors. It started as a contacts directory in 2019 and has since grown to include artist insights, tour tracking, jobs, news, a services marketplace, and more. In 2025, more than half a million professionals used one of ROSTR's products.

The ROSTR Group is a 100% independent, profitable business, owned entirely by its founders. Built for the business of music.
