From Tesco Media to Tomorrow’s Stack: Building Retail Media That Actually Works (Part 2)

With special guest Florian Clemens - ex-Director of Strategy, Proposition and Measurement at Tesco Media; built the global accounts team at Amazon Advertising.

Hosted by Viv Craske & Colin Lewis. Brought to you by Grace & Co, the marketing and commerce consultancy.

Part two of our special with Florian Clemens dives into the unsexy-but-critical machinery behind retail media: interfaces, platforms, ad policy, data sharing and measurement. We open with the tier-one question every retailer is asking - self-serve or managed service? - then move into how to design ad experiences without breaking the retail experience, why ad policy matters more than people think, and the big make-or-buy question facing every retail media network. Florian closes with a TLDR every retail media leader should pin to the wall: what is your theory of incrementality?

If you missed Part 1 on supply and demand, queue it up first...
