S imon Nixon is a self-made British billionaire entrepreneur who founded Moneysupermarket.com, one of the UK's first and most successful price comparison websites. A qualified accountant, Nixon dropped out of university to pursue his business interests. In the 1990s, he started a business that provided information on mortgage loans, which laid the groundwork for his future digital venture. He astutely recognized the power of the internet to empower consumers to compare financial products.

In 1999, he launched Moneysupermarket.com, a platform that allowed users to compare prices on mortgages, insurance, credit cards, and loans. The business was an immediate success, capitalizing on the dot-com boom and the public's desire for greater transparency in financial services. He took the company public on the London Stock Exchange in 2007. Over the years, he gradually sold down his stake in the company, eventually selling his last shares in 2016. Since then, Nixon has become a prominent investor, managing his wealth through his private investment office, which has a significant portfolio of technology investments and luxury real estate around the world.
