This episode unpacks the technical and strategic foundations retailers need to thrive when the disruptor becomes disrupted.
Key Discussions in This Episode
Introduction and Anne-Claire’s Role at Mirakl (04:48–06:48) Anne-Claire describes her three-part role: empowering Mirakl employees to leverage AI, disrupting existing products with AI capabilities, and building solutions that help customers capitalise on agentic commerce opportunities.
Defining AI and Agentic Commerce (06:48–09:42) Anne-Claire breaks down two core aspects of agentic commerce: shoppers using AI to discover and purchase products, and retailers using agents to accelerate operations. She discusses the evolution from today’s discovery tools to tomorrow’s autonomous purchasing agents that can hunt down rare items and complete transactions while you sleep.
The Changing Shopper Funnel (09:42–12:26) How AI is already disrupting shopping behavior: 60% of shoppers now use AI at some stage of their journey, searches have expanded from 2-3 keywords to detailed, contextual descriptions, and organic traffic to e-commerce sites has declined 10% in the first half of 2025 as consumers find answers directly on AI platforms.
Impact on Retail Media Revenue Models (14:02–18:53) The shift from keyword-based to intent-led search, with 37% of shoppers now using more than eight words in AI platform searches (up from just 4% in August 2024). Anne-Claire explains how retailers can leverage AI platforms as off-site placements, similar to Google Shopping, and create new sponsored placement opportunities within shopping agents.
Building a retail-media powered business in an emerging market
Episode 10
Tuesday, January 27, 2026 • Duration 35:43
Colin Lewis is joined by Ines Catao, Retail Media Director at Worten, for an in-depth conversation about building a marketplace-powered retail media business in an emerging market. Ines explains how Worten—Portugal’s leading electronics retailer with over 35% market share and 200+ stores—transformed its online marketplace into a high-growth advertising platform, achieving 300% monetisation growth and 800% ROAS in just seven months. The discussion covers the strategic shift from traditional retail to a media business, the power of marketplace democratisation for SMBs, and how Worten is bridging online and in-store retail media as it scales into 2026 and beyond.
Key Discussions in This Episode
Introduction to Worten and Ines’s Background (00:01–01:12) Ines introduces Worten as Portugal’s leading electronics retailer with over 35% market share, 200+ stores, and a strong online presence. She shares her own journey from seven years at Google in advertising across Europe to joining Worten two years ago to build the retail media business.
The Portuguese Market Context (02:11–05:44) Portugal’s 10 million population, strong culture of in-store retail, and rapid mobile adoption (80% of consumers discover brands on phones) create a unique opportunity. E-commerce is growing rapidly, but Worten is ahead of competitors with over 20% of sales online, compared to just 8% for other major Portuguese retailers.
The Marketplace Journey and Seller Growth (06:28–09:45) Worten partnered with Mirakl to launch its marketplace, now featuring over 3,000 sellers from 50+ countries. The “win-win-win” strategy benefits sellers (easy onboarding and shipping), consumers (increased choice), and Worten (new revenue streams and traffic). Sellers recently gained access to Worten’s first advertising offerings on the marketplace.
Democratizing Access Through Marketplaces (09:45–11:18) The marketplace model democratizes access to the Portuguese market for SMBs and international sellers, enabling small businesses to compete and scale. This aligns with broader European opportunities to help companies succeed in the online world.
The SMB Advantage in Retail Media (11:18–14:58) Unlike large brand budgets constrained by rigid allocation structures, SMB sellers can flexibly allocate and adjust their retail media spending based on real performance. This agility makes SMB budgets more effective and appealing to retailers building media businesses. Colin and Ines discuss how this flexibility in creative, capability, and budget reallocation creates competitive advantages.
The Future of Search and Interaction (18:53–23:31) Moving beyond traditional keyword search to conversational, multi-turn discovery where shoppers may see only 2-3 featured products plus 7-9 additional options, all matched to intent rather than keywords. The critical importance of product content and embeddings over traditional keyword optimisation.
Category-Specific Adoption Patterns (24:08–27:36) Discussion of how agentic commerce will capture significant goods transactions—McKinsey projects $1 trillion in the US and $3-5 trillion globally by 2030—with varying adoption rates across categories, price points, and demographics.
The Death of Traditional Personalisation (28:48–31:10). Why “the personalisation you used to know is dead”: AI platforms already possess deep contextual knowledge about users that far exceeds traditional CRM and customer data platforms. The importance of enhancing product content to match shopper intent and problem-solving needs.
Voice and Visual Search Adoption (31:10–34:25) Current trends indicate that shoppers prefer speaking to AI (typing while walking) over full voice conversations, as well as the significant adoption of visual search—photographing items to find matching products or even generating shopping lists from fridge contents.
Building Shopping Agents: Retailer Strategies (34:25–37:39) How advanced US retailers are converging on unified customer-facing agents with specialised sub-agents behind the scenes handling specific tasks like inventory checking, customer service, and returns processing.
Navigating a Rapidly Evolving Ecosystem (37:39–40:34). Why this isn’t a “winner takes all” situation, the parallels to the mid-1990s internet emergence, and the critical need for interoperability and an agentic client layer that can connect to multiple protocols and platforms as they evolve.
Implications for Marketplaces (41:25–45:21). How curated marketplaces become even more valuable in an AI-driven discovery environment, the heightened importance of accurate pricing, availability, and delivery date promises, and why these fundamentals remain critical regardless of interface changes.
Final Advice and Takeaways (45:21–46:52) Anne-Claire’s TLDR: Start experimenting now, understand how shopper behaviour is changing, build critical foundations, improve product content to match intent, and maintain marketplace fundamentals while testing new approaches.
Segmented Retail Media Strategy (14:58–18:27) Worten structures its retail media into two distinct offerings: a full-funnel brand proposition (awareness, brand consideration, market share) competing with TV, Google, and Meta, and a performance-focused seller offering (consideration and conversion) designed for rapid ROI. This segmentation ensures Worten differentiates itself from traditional advertising channels and meets each customer segment’s unique needs.
The Importance of Differentiation (15:26–17:18) To stand out against established advertising players, Worten emphasizes what makes retail media unique: direct consumer insights, the ability to test products in-store and online, direct access to Gen Z, and opportunities to experiment with packaging and positioning. Big brands love innovation, and Worten’s differentiated offering gives them a reason to invest.
Strategic Transformation and Change Management (19:23–21:55) Two years ago, Worten made a pivotal strategic decision to professionalize retail media as a true marketing channel. This required top-down leadership support, cross-team collaboration, aligned KPIs, and educating the organization that this represented a significant shift after 20+ years of traditional retail operations. Success came through communication, alignment, and crediting teams across the business.
Building Buy-In Through Influence and Results (21:55–25:54) Change wasn’t easy initially—there were roadblocks and closed doors. However, Ines emphasizes education, persuasion, and demonstrating impact. After 9–12 months of persistent effort, the organization saw the untapped potential and began cheering for retail media. The key was showing concrete results for the business, brands, and customers while staying true to Worten’s mission of customer satisfaction.
Marketplace Ads: Rapid Adoption and Growth Metrics (28:37–31:00) When Worten introduced its ads program powered by Mirakl technology, adoption exploded. From fewer than 30 sellers, the program grew to over 350 sellers in just seven months. Monetization revenue jumped 300%, and sellers experienced a 40-percentage-point boost in their ability to generate sales within the marketplace—a clear win-win outcome.
ROAS Performance and the Role of E-Commerce Excellence (31:33–34:13) Worten achieves over 800% ROAS on its marketplace retail media. This exceptional performance stems from the e-commerce team’s strong and growing conversion rates (powered by AI-driven content creation, optimization, and catalog management). Retail media benefits directly from a high-performing e-commerce platform; the two are inseparable.
Pragmatic AI Usage in Emerging Retail Media (34:13–35:04) While AI is critical to Worten’s e-commerce operations, Ines believes retail media needs to mature further before advanced AI optimization becomes the priority. Currently, Worten uses AI moderately—in internal tools, collaboration with e-commerce, and the Mirakl ad server—but focuses on getting the basics right during this fast-growth phase rather than optimizing decimal points of yield.
2026 Roadmap: In-Store Placements, Omnichannel Integration, and Marketplace Scaling (35:04–36:55) Worten’s 2026 strategy includes three major initiatives: launching in-store ad placements by year-end, connecting the online ad server with in-store bookings for a seamless omnichannel experience, and tripling last year’s marketplace ads objectives. The focus is on integrating stores and online, measuring performance together, and delivering continued growth for sellers.
