Swedish entrepreneur and a technologist, Daniel Ek has a net worth of $310 million (£190m) as of April 2012, according to the Sunday Times UK Rich List. He made commercial websites on school computers, recruiting his friends and netting $15,000 a month. Ek started a company aged 14 before founding Advertigo, the online advertising company. Based in London, he was millionaire by 23, and is now sitting on £190 million. He inspires a mixed reaction from music-lovers, but has stated his ambition to run the biggest music site on the internet. He co-founded the Spotify internet music streaming service in 2007 that is easy to use as iTunes and as social as Facebook. It also pays 60-70% of its income to the music industry. The Swedish software programmer and amateur musician launched the product in Europe in 2008 and in America in summer 2011.
