    Brands Move From AI Experimentation to Adoption

    At an ADWEEK House Cannes Lions panel co-hosted with Zefr, industry leaders discussed practical steps for turning AI experimentation into business value for marketing organizations. Panelists emphasized building data-driven foundations—standardizing data, measurement and decision frameworks—creating knowledge hubs to retain learnings, and redesigning workflows rather than merely layering AI onto existing processes. Speakers also said the primary barriers are organizational: internal resistance, the need for executive support, and education. The session encouraged marketers to experiment with AI tools and cultivate internal evangelists to integrate AI responsibly into day-to-day operations.
