μTorrent, working with μTorrent founder
Ludvig Strigeus until μTorrent was sold to

Spotify The sale of Advertigo as well as his previous work made Ek wealthy enough that he decided to retire. However, after a few months, he realized he wanted a new project, leading to him founding Spotify. Ek first had the idea for
Spotify around 2002 when peer-to-peer music service
Napster shut down and another illegal site
Kazaa took over. Ek said he "realized that you can never legislate away from piracy. Laws can definitely help, but it doesn't take away the problem. The only way to solve the problem was to create a service that was better than piracy and at the same time compensates the music industry – that gave us Spotify." In October 2008, the company launched its legal music streaming service
Spotify. Initially, Spotify ran on a peer-to-peer distribution model, similar to μTorrent, but switched to a server-client model in 2014. In October 2016, Spotify co-founder Martin Lorentzon announced he would be stepping down as chairman and Ek would be taking over alongside his role as CEO. and as of June 2017 had raised over $2.5billion in
venture funding. In 2017, Ek was named the most powerful person in the music industry by
Billboard. In May 2022, Ek invested an additional $50million to acquire more Spotify shares, citing an optimistic future outlook for the streaming giant. Spotify at that time had 182million paying subscribers and was growing at 15% year on year. On 30 September 2025, Ek announced that he would step down as CEO of Spotify at the end of the year, while remaining as executive chairman. In the role, his succeeding co-CEOs will continue to report to him, while he focuses on capital allocation, long-term strategy, and regulatory efforts.

The company emerged from stealth mode in 2023 showcasing its non-invasive full-body scanning technology, which uses sensors and artificial intelligence to collect and analyze health data. Initially self-funded with €30million from Ek through his investment vehicle, the company has since received backing from outside investors. The company operates in Stockholm and London as of 2024.
