Dunn, 52, and Humby, 56, are the brains behind Tesco’s hugely successful Clubcard scheme.
They started their west London business, Dunnhumby, from a spare bedroom in 1989. The supermarket giant bought stakes at regular intervals and recently spent £48m acquiring the final 10%.
The married couple made a total of £96m from the proceeds, the Sunday Times Rich List valued them at £90m after tax, taking other assets into account. They currently have a net worth of $140 million.
