Top 100: 33. Jack Dorsey

Executive chairman and co-founder, Twitter and Square

A new entry in the Top 100 last year, Jack Dorsey has continued to change the way fashion retailers work online. This year has seen the sector use Twitter in a number of successful marketing campaigns, including Selfridges’ 12-hour ‘Jean-a-thon’, Topshop’s Halloween campaign introducing a ‘Twitter currency’ and Armani’s ‘Tweet Talks’. His mobile payment service, Square, relocated to a bigger head office and Dorsey plans to roll it out on an international level. He also released new features on Twitter, allowing users to add photos to the header of their profiles, using images in a similar way to Facebook and Instagram - the competition is still rife as to which platform will triumph with consumers over the next 12 months.
