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.

The values advocated by Contributing® and that we promote at the agency:

Confidence in oneself, in the future and in others. To elaborate Contributing® strategies is to push back any fatalism, any immobilism, by federating the maximum of active, enthusiastic and competent contributors, ready to invent new solutions in front of the complexity.

The Social Man.
Digital capitalism is the big winner of the Covid crisis and risks hypertrophying an individualism that is already well established in society. The Observatoire de la marque France shows how sick the “nous” in France is. The French, seeking to protect themselves, have put their carts in a circle, in an assumed “ego-logy”. Brands committed to Contributing® will be able to defend the idea that, despite physical (not social) distancing, consumers will always need relationships and conversation to be social.

The technological domination of the GAFAs preempts entire areas of our social life. As Vincent Mayet mentions, access for Google, the market for Amazon, relationships for Facebook, creativity and entertainment for Apple are a real threat to our individual freedoms
Contributing® should stand with those who fight to defend their technological sovereignty and preserve freedoms.

It is of course about the big balances (CO2 emissions, global warming, energy decrease…), but also about the small ones: personal life, professional life, working conditions, telecommuting… Contributing® will have to place architectural, physical and behavioral dimensions at the heart of the consumer experience.
