About Audrey

10 years of experience at the intersection of media buying and business development at TF1, Havas, Publicis, Seedtag, and Criteo. I can leverage my skills to support you in your short-term or long-term missions.

I have had the opportunity to work for/with various clients (e.g., FDJ, Essity, L'Oréal Groupe, Swarovski, KFC, Stellantis, Visa, Pierre Fabre...), so I have diverse industry knowledge.

What I bring: a grounded, hands-on perspective from both sides of the market. I know how agencies think, how media representatives negotiate, and how brands can invest their media budgets more intelligently.

I support ambitious brands with their media strategy, their advertising investment choices, and their agency relationships.
