Stephen Howard-Sarin

Stephen Howard-Sarin has spent 10+ years' operating at the intersection of commerce and advertising and is currently the Managing Director of Retail Media Americas at Criteo. He leads a fantastic team that owns retail media partnerships with dozens of retailers and thousands of brands. Previously, he was VP of Retail Media at Instacart and VP of Strategy & Transformation at Walmart, where he architected the company’s expansion in advertising starting in 2017. Stephen earned his programmatic stripes at eBay Advertising before that, as Senior Director of Sales, Marketing & Analytics. Throughout his career, Howard-Sarin has helped build hypergrowth ad businesses adjacent to core commerce. Transaction-based first-party data fuels ideal marketing outcomes, but advertising is not a core competency of most commerce companies. There are significant gaps in culture, talent and technology that hamper retailers from becoming great at advertising – and Stephen loves to build bridges across those gaps.

Day 2, Tuesday, March 10

8:50 AM Presentation: The AI Powered Shopper: What the New Journey Means for Marketers

The rise of the AI powered shopper is reshaping how people discover, evaluate, and buy. Journeys are no longer linear — they’re fluid across retailers, search, social, and now AI agents that actively participate in research and decision-making. As media and commerce converge, commerce data has become the connective tissue that powers relevance, personalization, and measurable outcomes. This session will explore how agentic commerce is emerging as a new discovery layer, why it’s additive rather than disruptive, and what marketers must do now to stay visible in an AI driven shopping landscape.

Objectives:

  • Detailing how AI and agentic shopping are changing the consumer journey and expanding retail media.
  • Learning why commerce data is becoming the foundation of addressability, relevance, and performance.
  • Sharing the practical steps brands should take now to prepare for the next wave of AI powered commerce.
