Ambitious by nature
Driven by creativity
Thrilled by innovation


The strategic and creative agency dedicated to brands.

At W, as entrepreneurs, we believe in a new vision of marketing and communication: CONTRIBUTING®, a new approach to safeguard brands from the depression of a belt-tightened world, marked by a contraction in consumption, travel and other sectors.

Marketing needs to evolve and make way for an entirely new form of brand art. Brands need to drive a fresh and positive contribution to re-enchanting the world in a new way.

They need to generate change and pride in-house, stand as an emotional link and landmark for users, and create growth for markets and shareholders. Brands are an integral part of our world. They make us think, laugh, feel and dream, and sometimes open new paths.

Our role is to be by their side, guiding them and helping them to be fully in step with their times and the focus of attention.


Our Mission

Create brand ideas that contribute to the new challenges of society, transform them into experiences and activate them in their communities.

Our secret

A positive and committed vision of society and a business model that is unique in France, grounded in three areas of entrepreneur-driven expertise: branding, architecture, and advertising & content.
