Kerr (pictured) is taking over from Richard Stillwell. Kerr has been chief executive of Deloitte Consulting and was most recently its global vice-chairman between 2016 and 2018.

He led the creation of Deloitte Digital in 2012, the first dedicated digital consulting business, and grew the business organically and by strategic acquisition to $4bn in revenue with operations in 30 countries.

Previously called St Ives, Kin + Carta has been shifting to a digital marketing business and this appointment is part of that strategy.

J Schwan, chief executive officer of Kin + Carta, said: “We set out on this search to find a chairman with deep experience scaling technology service businesses on a global scale. We found all of that and more with John. John is a pioneer in the business transformation arena.  His experience building and scaling Deloitte Digital fits perfectly with Kin + Carta’s plans to build a business which addresses the growing demand for digital transformation.”
