James Avery is joined by Melissa Burdick, Co-founder and President of Pacvue, to discuss the complex, multi-touchpoint journey of the modern consumer. Melissa breaks down the three pillars of commerce media: discovery, retail media, and the emerging world of agentic commerce. She also explains why brands are shifting their focus from basic ROAS to sophisticated incrementality (iROAS) models. The conversation highlights the technical necessity of an "API-first" strategy for retailers to attract top-tier brand spend and explores how tools like Amazon’s Rufus and AI-powered assistants are reshaping discovery and increasing basket sizes.
