In a digital world where brands compete for attention in the same environments, the future of advertising is no longer just about creating better ads, it is about understanding the culture and behavior of each platform itself. In this session, Francisco Martín Vera and Andreas M. Stefansen will explore Stellar's Media First Approach, a philosophy where the media environment becomes the starting point of the creative strategy. Instead of adapting media to the ad, brands must adapt creatives to the ethos of each platform and community. Through real campaign case studies and market insights from platforms such as BeReal, Strava, dating apps, and other emerging media ecosystems, they will showcase how platform-native creativity and contextual relevance are becoming key drivers of modern advertising performance
