Boomtown Rats frontman and Live Aid getter-together Geldof (64) has made far, far more from his business interests than he ever did from music. Last year he recalled that in 1978 the Boomtown Rats turned down a $100,000 cheque to perform at a company event in California, proposed by a young tech entrepreneur called Steve Jobs. "It was a lot of money and they were being hip and cool." But Geldof said the punk band told Apple: "We don't do corporates."
But his business smarts developed as the music career wound down. He banked €8m from the sale of the Planet 24 TV production company and dabbled in the internet during the first dotcom boom. But the real money came from reality TV, especially from the Castaway show which has been a cashcow for Geldof and his partners. Dun Laoghaire-born Sir Bob has shared in €38m in dividends, including a €2.97m payout last year. He owns property in London and a renovated monastery in Kent. He has backed a number of start-ups including ed-tech firm Groupcall.
