MullenLowe London

MullenLowe's logo neatly illustrates why the group calls itself “a different kind of beast”.

Alongside its marketing comms network, it has other divisions which comprehensively come in from all angles to help inform the creative – data analysis, experiential, media buying – you name it, they do it. Plus they do like to challenge the status quo, which you don't often see in a beast of this size, even if it is a boxing octopus.
