About

SUM is a London based full-service branding and marketing agency, working with ambitious luxury and lifestyle clients across the globe.

Partners in luxury branding

A passion to be different lies at the heart of Sum’s agency model

Most branding and communications agencies apply their talents across many product categories. SUM was built to do the opposite: to work within one narrower world, and to know it thoroughly.

For more than twenty-five years the agency has partnered only with clients committed to making a genuine impression in luxury and lifestyle, whether an established house or a brand that does not yet have a name.

That focus shaped the agency model. Each client is given a single point of creative leadership across the full range of branding and marketing disciplines, so that strategy, identity, content and marketing are handled as one programme rather than as separate appointments, and the client is free to concentrate on the business itself.

“At the agency’s core lies a deep understanding of the luxury consumer, and this mindset touches everything we do.”
