Reporting from Cannes Lions, I sat down with Dr. Mark Grether, SVP & General Manager at PayPal Ads, to explore a different perspective on retail media, one that cuts through the constant stream of announcements and focuses on solving real advertiser challenges. We discussed why PayPal is choosing not to chase the latest product launch headlines and instead is doubling down on helping the market understand the unique advantages of its existing capabilities.

We also dug into one of the industry's most debated topics: shoppable ads. Why have so many shoppable ad initiatives struggled in the past? What makes PayPal’s approach different? And how could identity, payments infrastructure, and changing consumer behavior — especially in an AI-powered world — reshape how brands reach and convert shoppers? Tune in for a fascinating conversation about the future of retail media, commerce, and customer acquisition.
