Global Trading and Accountability Director

Buying, Trading & Investment London, England


Position at m/SIX

Who are m/SIX? 

m/SIX are one of the world’s fastest-growing media planning & buying agencies, having doubled in size in the last two years. Our international network now comprises over 40 offices across 3 continents. 

We have a unique proposition and ownership structure, which is fundamental to how we operate for our clients. We are majority owned by our partners within The&Partnership, but our joint venture with WPP means that we are able to offer a true ‘best of both worlds’ advantage. This means a progressive and entrepreneurial approach to business and culture, whilst providing full access to GroupM’s market-leading pricing, data, and technology assets.                                                 

As both The&Partnership and m/SIX we have therefore created new models and ways of working which are leading the industry in defining the agency of the future. This means solutions built bespoke for clients’ individual needs, inclusive of all necessary disciplines and working to one bottom line. Creatives, strategist, analysts, investment and production teams working together, with data and technology at the centre. These teams are often implanted directly within the client marketing teams: in the UK we have fully embedded teams at EA, News UK, Talk Talk and Toyota/Lexus. The impact of this has been transformational on our clients’ business. 

As a direct outcome of this progressive & transformational agenda, m/SIX has one key ambition: to be the most important place in the careers of our people.
