Meanwhile, Cooke told Campaign: "We already have three or four clients lined up, from the luxury, technology, sports and car sectors. We will be using insight from other industries to help clients be progressive and innovate.

"There is no English Steve Jobs, but watch this space."
Cooke was one of six marketers nominated for this year’s Marketing Society Marketing Leader of the Year award, won by Sainsbury’s Sarah Warby.
