Daniel Ek

Daniel Ek, co-founder and CEO of music streaming service Spotify. Mark Coles tracks the life of the shy Swede transforming the music industry.

This week 35-year-old Daniel Ek became very, very rich when his company Spotify floated on the New York Stock Exchange - with an initial value of more than $26 billion.

It's a long way from his home in a working-class suburb of Stockholm where Daniel's interest in both music and computers was piqued at an early age.

He started his first businesses while a teenager, in between starring in school musicals, and earned his first fortune in his early 20s.

He launched Spotify in 2006 with business partner Martin Lorentzon, with a goal to 'save the music industry' at a time when illegal downloads were eating into profits.

Today Spotify has revolutionised the way we listen to music and last year Daniel Ek was named the most-powerful person in the music industry by Billboard magazine - but what does the future hold in store for the tech industry
