Johann Barsby is Managing Director at Publicis Commerce, working at the frontier of commerce, Retail Media, and data-driven growth. His role: helping brands navigate the shift from traditional digital commerce to a world where media, marketplaces, and performance are fully interconnected.
For nearly 15 years, he has been operating at the core of e-commerce ecosystems, supporting international brands in their transformation across Retail Media, marketplaces, and omnichannel performance. His work focuses on turning complexity into competitive advantage — structuring growth across platforms, activating data at scale, and building sustainable performance models.
Johann is particularly recognized for his vision of commerce as a unified system where brand, media, data, and technology no longer operate in silos, but as one continuous, intelligent growth engine. His expertise spans Retail Media strategy, marketplace acceleration, and the emerging role of AI in shaping the future of shopping and marketing performance.
As a speaker, Johann regularly contributes to conferences, roundtables, and industry events to share his perspective on the future of retail, platform economies, and the rise of AI-driven and agentic commerce. His ambition is to inspire leaders, brands, and organizations to rethink how growth is built in an increasingly automated, data-powered, and experience-driven commerce landscape.
