WPP has appointed Guillaume Epstein as its first global head of commercial. 

The role is designed to streamline how the holding company manages pricing, contracts and client negotiations across its worldwide network.

Epstein joined from digital transformation consultancy Valtech. Before that, he spent over a decade at Publicis Groupe, holding senior finance and commercial roles across Europe, Asia-Pacific and Latin America. His most recent position there was SVP and global commercial finance director. 

The appointment is part of WPP’s push to simplify its operating model. Large global clients have increasingly demanded cleaner, more unified agency relationships. WPP is responding.

The holding company has been restructuring steadily under CEO Mark Read. It has consolidated agencies and cut operational complexity following years of acquisitive growth. Creating a dedicated global commercial role signals that standardising pricing and contracts is now a formal strategic priority.

For clients, a more consistent commercial framework could mean fewer variations in how deals are structured across markets. That is something multinationals negotiating global contracts have long pushed for.

Epstein’s cross-regional background across three major markets makes him a strong functional fit for the role.

WPP has not disclosed a start date.
