In this fireside chat, Colin Lewis is joined by Ines Catão, Retail Media Director at Worten, for an in-depth conversation about building a marketplace-powered retail media business in an emerging market. Ines will share how Worten, Portugal’s leading electronics retailer with more than 35% market share and over 200 stores, transformed its online marketplace into a high-growth advertising platform, delivering 300% monetisation growth and more than 800% ROAS in just seven months. The discussion will explore how Worten evolved from a traditional retail model toward a more sophisticated media business, while creating differentiated propositions for both major brands and SMB sellers. It will also examine the role of marketplace democratisation, operational scale, automation, and cross-functional alignment in making that growth possible. Looking ahead, the session will focus on how Worten is connecting online and in-store retail media and building a model designed to scale profitably into 2026 and beyond
