Kobalt Intro:

​Kobalt is one of the world’s largest, most innovative music companies, using technology to power creative freedom, transparency, ownership and control for artists, songwriters, publishers, and labels.

Founded in 2000 by Swedish entrepreneur Willard Adhritz, the startup built a platform to maximise efficiency, accuracy, and transparency across the billions of micro-payments collected in today’s highly complex digital world. As the traditional music companies fought technology and contracted, Kobalt embraced it and grew, building an infrastructure and world-class creative team purposely designed to usher in the streaming era, along with a more fair, rewarding music business for creators. Our technology enables them to access royalty payments 4x faster while also maximising the royalty collection amounts.

With over 400 eployees in 12 offices around the world, Kobalt today represents over 31,000 artists and songwriters, 700,000 songs and 600 publishing companies. Kobalt is proud to work with artists, songwriters, and companies like Childish Gambino, Max Martin, Paul McCartney and MPL Communications, Disney Music Group, and many more.


​​Kobalt continues to grow 3x faster than the market and as such has a continuous focus on scaling out its systems, products and services to cope with the increasing demand. One of the key opportunities for Kobalt is to address the masses of songwriters that are reasonably early in their careers and as such struggle to get representation from strong publishers. As most publishers depend on primarily manual processes, the cost of service usually outweighs the revenue potential that those songwriters would generate. Through technology, Kobalt aims to reduce the cost of service for each individual songwriter, making it viable to support large numbers of songwriters at a marginal cost.
