Your Share, Not Your Sales: Rethinking Retail Media Measurement with Matthew Fantazier
James Avery sits down with Matthew Fantazier, VP of Retail Data Partnerships at The Trade Desk, to unpack the first-of-its-kind three-way partnership between The Trade Desk, Dollar General, and Kevel that brings onsite retail media into the same programmatic workflow as offsite. Matt spent 19 years on the advertiser side at J&J and Kenvue before moving to The Trade Desk, and he brings that buyer's perspective to why fragmentation has become the industry's core problem: brands are managing 300+ retail media networks which makes frequency control, optimization, and consistent attribution nearly impossible. The conversation covers what actually unlocks brand and agency budgets (make it simple, then lean into what only you can offer), why commerce data's deterministic view of real purchase behavior is only valuable if activated intentionally, and why incrementality, new-to-brand, and category share matter more than ROAS as a measure of whether a brand is winning. Matt and James also dig into how CTV fits into a connected funnel, why store-level and regional share data can reshape a messaging strategy, and Matt's prediction that "retail media" will be an archaic term within five years, replaced by retail data, retail inventory, and retail measurement inside a single unified media plan. If you're running a retail media network and trying to understand where you fit in the broader media ecosystem, this episode is essential listening.
