Simon Fuller
Rank 2017

David Beckham (qv) and Sir Andy Murray are helping making a fortune for Pop Idol creator Fuller – and the former talent scout is easily worth more than both of them. Profits at the Cyprus-born entrepreneur’s management firm, XIX Entertainment, soared sevenfold to £10.9m in 2015. Fuller, 57 later this month, is collaborating on a virtual-reality venture with Swedish supergroup Abba. He is also a co-owner of the 22nd Major League Soccer franchise in Miami with Beckham, who alongside his wife Victoria is one of his top clients. Last year Hastings-raised Fuller sold a Beverly Hills mansion for $14.6m, having bought it for $8.5m in 2005.
