Today, hundreds of people (and counting) work out of the company's HQ in the Swedish capital, and Forster is the managing director for the Nordics, the five biggest countries in Northern Europe.
Their mission: to make sure everyone gets to enjoy legal music, wherever they are, on their smartphones, tablets and desktop computers.
Spotify isn't quite there yet, but it's well on its way; earlier this week, the company announced that it now has 40 million active users around the globe (across 56 markets), 10 million of which are paid subscribers.
A big milestone any way you slice it, especially given the increasing global competition (and many other reasons why its continued growth is a challenge that's not to be underestimated).
I recently caught up with Forster at Spotify's headquarters in Stockholm as part of a tour of local technology companies, and also captured some photos to reflect the culture at the offices (see below).
In the interview, Forster walked me through some of the recent achievements and product launches, why the Nordic countries are still such a crucial part of Spotify's overall business operations, the importance of the U.S. market and Spotify Connect, future geographical expansion and the company's place within the Stockholm tech scene. Enjoy (and share) the video above.
