Gregoire Assemat Tessandier, a business mind with a creative heart.
For more than 20 years, my career has sat at the intersection of business, creativity, marketing and technology—building organizations, transforming global client partnerships and helping ambitious brands navigate change.
Today, as a President at Publicis in the USA, my role spans large, multidisciplinary organizations across brand, creative, media, CRM, data, content, technology and transformation. The work covers major integrated structures in consumer technology, healthcare and enterprise content transformation.
Alongside these responsibilities, I serve on the executive committees of several of Publicis Groupe’s largest organizations, contributing to strategic direction, governance, operating models and commercial performance.
Across New York, London and Paris, I have built, scaled and transformed businesses through periods of growth and reinvention. Much of that work has involved bringing together different capabilities, cultures and leadership teams around a shared ambition: creating breakthrough work that delivers sustained business impact.
That journey has included leading transformation strategy for a global pharmaceutical company; helping an investment bank build its first direct-to-consumer product; partnering with a legacy media leader to create its streaming platform; and developing the first global B2B brand program for one of the world’s most valuable consumer companies.
It has also included major assignments across technology, financial services, entertainment, sportswear, fashion and luxury, working with some of the world’s most recognized brands.
The strongest organizations connect strategy, creativity, technology and culture. My focus has always been on aligning those forces—navigating complex global environments, building high-performing teams and turning ambitious ideas into measurable growth.
I entered the creative industry to do brilliant things with smart people for great brands.
