For too long, advertisers have faced an uncomfortable choice: buy at national scale and accept a one-size-fits-all message, or invest in regional networks and drown in complexity. The same dilemma has haunted retail media networks trying to grow without cannibalizing the differentiated value that makes local and regional players worth buying in the first place.

This roundtable asks how new CMN/RMN partnerships can dismantle that trade-off. This requires shared tech infrastructure, coordinated data models, and go-to-market frameworks designed to protect, not flatten, what makes each network distinct. We'll explore what it takes to make partnerships work: the data negotiations, the sales team alignment, the account-coverage models, and the unexpected speed bumps.

For brands and agencies in the room, the stakes are just as high: if this model works, managing seven separate RMN relationships to achieve national reach may no longer be the only option. The question on the table is whether "national scale plus local relevance" is finally achievable without the trade-offs, and what everyone in the ecosystem needs to do differently to get there.
