Retail Media Breakfast Club

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 This one raises big questions about where commerce media is headed and whether the current playbook is already outdated.

EMARKETER is teaming up again with Bain to survey retail media network leaders for a unique insight into the forces shaping the industry. The survey is intended for people working in-house on retail media teams, and it is global this year! The survey is also double-anonymized. The survey organizers will not know, nor are they trying to determine, which specific retail media network a respondent works for. The goal is to understand broader retail media trends, not attribute responses to individual companies. Please take the survey here.

Today I unpack a contrarian take that’s been sitting with me since my conversation with James Deaker on The Yield Doctor: what if the biggest threat to retail media is already here, but no one has the incentive to talk about it? I replay snippets from my convo with James, and dig into how AI-enabled commerce is reshaping the shopper journey long before customers ever land on a retailer’s site, and why that creates a structural risk for the entire retail media model.
I also explore the uncomfortable truth about leadership incentives: why retail media executives may be disincentivized from sounding the alarm, even as behavioral data signals start to disappear and ad surfaces lose relevance. This isn’t about the death of retail media, but it is about a major reset. The question is: who’s actually preparing for it?

A few weeks ago, Kroger Precision Marketing announced a major partnership with Google that allows brands to activate Kroger audiences directly inside YouTube and DV360 while tying campaign measurement back to actual Kroger sales. On the surface, this looks like another retail media expansion story. But in this episode, I share snippets of a recent LinkedIn Live, and unpack why it’s actually something much bigger.
On the livestream I was joined by Christine Foster from Kroger Precision Marketing and Jon Flugstad from MetaRouter to explore the real competitive advantage emerging in commerce media: context. We discuss why retailer-owned shopper intelligence is becoming more valuable than rented identity solutions, how loyalty data changes the game for omnichannel measurement, and why the future winners in retail media won’t necessarily be the retailers with the most ad products, but the ones with the strongest infrastructure

Timeline
[00:00] Why Kroger’s Google partnership is really a story about shopper context, not just media activation 
[01:00] What retailers uniquely own that platforms and infrastructure companies can’t replicate 
[02:22] Christine Foster explains how Kroger’s 20+ years of loyalty data powers trusted audience intelligence 
[04:14] Jon Flugstad breaks down the fragmented retail media tech stack and why reconciliation is so difficult 
[05:30] Why retailer-owned context is becoming the “gold” of commerce media in the AI era 
[07:18] How Kroger designed its Google integration to give brands self-serve activation directly inside existing workflows 
[09:37] Why omnichannel visibility across online and in-store sales is the next evolution of retail media measurement 
[10:58] My biggest takeaway: the future winners in commerce media will be defined by infrastructure and context layers, not ad formats

Today I dive into a powerful idea that completely reframed how I think about retail media in relation to communicating narrative. After listening to a conversation featuring Joe Zappa on the AdTechGod Pod, I couldn’t ignore how directly his framework applies to our world. We’re not struggling with innovation: we’re struggling with storytelling.
I unpack why so many retail media announcements fall flat, even when the products themselves are solid, and what’s missing from the way we communicate value. I explore how shifting from feature-first messaging to problem-first narratives can transform how brands, agencies, and the industry as a whole responds. Plus, I break down practical ways leaders can stand out: not by being louder, but by being clearer and more intentional with their voice.

[00:00] - Why I’m looking outside retail media to rethink how we tell our story
[01:00] - The core problem: leading with features instead of fixing what’s broken
[02:30] - Why most retail media announcements fail to answer “why should anyone care?”
[03:30] - The real opportunity for executives: sharing learnings instead of self-promotion
[05:15] - A simple 4-part framework for creating impactful LinkedIn content
[07:30] - Why being present and opinionated beats being technically “different”
[08:45] - The shift retail media needs: from “we launched” to “here’s the problem we solve”

Which of these deserve a deeper dive? Which ones are hype vs. a real opportunity? Let’s figure it out together.
