M artin Lorentzon is a Swedish technology entrepreneur who co-founded two highly successful companies: the digital marketing firm Tradedoubler and, most famously, the music streaming giant Spotify. After establishing and taking Tradedoubler public, Lorentzon used his wealth to provide the crucial initial funding for his next venture. In 2006, he co-founded Spotify with the technical visionary Daniel Ek. While Ek became the public face and CEO of the company, Lorentzon was the key early investor and served as the company's chairman for many years, helping to guide its strategy.

Spotify revolutionized the music industry by pioneering a legal, subscription-based streaming model that offered users access to a vast library of music. The service grew to become the world's largest and most dominant music streaming platform, with hundreds of millions of users. The company's successful direct listing on the New York Stock Exchange in 2018 turned both Lorentzon and Ek into multi-billionaires. Lorentzon has since stepped down as chairman but remains on the board and is one of the company's largest individual shareholders.
