At December19, our ‘Clearly Effective Media’ approach is entirely centred around our Clients' desired business outcomes, driving long-term, sustainable growth. We take great pride in the longevity of our Client relationships, with an average tenure of 4.3 years. We combine cutting-edge data analysis with our bespoke planning philosophy, Prism, to ensure that every pound spent drives maximum results. At the core of our process is the belief that every client's business challenge is unique, requiring a tailored approach. We adapt our planning process, Prism, to address the unique challenges your business faces, delivering tailored plans that prioritise individual Client needs.

We are a B Corp agency, embodying our philosophy of 'Doing The Right Thing' through transparency and trust in every project we undertake. Our success is measured by more than just metrics like GRPs; every campaign we design includes a distinct measurement target and framework to track effectiveness in meeting business goals. We don't rely on short-term tactics but focus on long-lasting creativity that drives fame, attention, and memorability. Our dedication to client service, working as Partners, is reflected in our 2024 survey, where 100% of our Clients would recommend us. As a People-focused agency, we are also committed to developing future marketing stars, proven by our third consecutive accreditation for IPA CPD Gold status.
