Global Client Finance Manager

Finance & Commercial London, England


Who are m/SIX?

m/SIX is one of the fastest-growing media planning and buying agency, with an 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 GroupM’s minority ownership 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. The&Partnership overall has a strong ethic of pitching in and getting our hands dirty, regardless of level. As such we are naturally less hierarchical and territorial than many other agency environments, particularly when it comes to working with creative teams.

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, the impact of this has been transformational on our clients’ business.

The agency is designed to think audience first – to face into disruption. We use data signals to understand the flow of audiences and build communications systems that balance the need to build and convert demand. We turn real behavioural data into actionable human insight that informs all communications at both strategic & implementational levels. This means that we’re geared toward business growth, not just media growth. Our aim is always to become a valued board-level business partner of the clients we work with.

As a direct outcome of this progressive & transformational agenda, m/SIX has two ambitions. To be a top ten agency in every market in which we operate, and to be the most important place in the careers of our people.
