About this event

We invited Thorold Barker, the Wall Street Jornal Editor for EMEA to have a fireside chat with Sir Martin Sorrell. 

Sir Martin Sorrell is Founder and Executive Chairman of S4 Capital plc, which is building a purely digital advertising and marketing services business for global, multinational, regional, local clients and millennial-driven influencer brands

Sir Martin was CEO of WPP for 33 years, building it from a £1 million “shell” company in 1985 into the world’s largest advertising and marketing services company. When Sir Martin left in April 2018, WPP had a market capitalisation of over £16 billion, revenues of over £15 billion ($20 billion), profits of approximately £2 billion and over 200,000 people in 113 countries. Prior to that, Sir Martin was Group Financial Director of Saatchi & Saatchi plc for 9 years and worked for James Gulliver, Mark McCormack and Glendinning Associates before that.

S4 Capital plc merged with MediaMonks, its content practice, in July 2018 and MightyHive, its programmatic practice, in December 2018 and has added eight further content programmatic and data companies to both practices in 2019, six in 2020 and four in January 2021. It is listed on the London Stock Exchange under SFOR.L and after a little over two years, S4 Capital plc has over 4000 people in 31 countries, with a market capitalisation of $4 billion.

Sir Martin supports a number of leading business schools and universities, including his alma maters, Harvard Business School and Cambridge University and a number of charities, including his family foundation.
