## Resource

Most retail media networks are built to look backward. But what if the real opportunity is predicting what customers will do next? In this episode, a reprise of my recent article for The Drum, I dig into a fascinating new model that challenges the industry’s reliance on transaction data and closed-loop attribution. I’m unpacking my recent conversation with Marco Steinsieck, former head of Sephora’s media network and now GM of Backpack Media, an education-powered commerce media network built on Sallie’s ecosystem. I also play a snippet of Marco's recent appearance on The Middlemen podcast to explore how life-stage signals — like planning for college or making first financial decisions — might be a far more powerful indicator of future purchases than anything sitting in a transaction log. This one raises big questions about where commerce media is headed and whether the current playbook is already outdated.
