Shopify Embraces AI Agents to Revolutionize Online Shopping
Shopify president Harley Finkelstein told attendees at the Upfront Summit that the company is “going all in” on agentic shopping — autonomous, agent-driven personal shoppers that can discover, compare and purchase products on behalf of consumers. Finkelstein argued agentic agents could expand online commerce (noting roughly 18% of U.S. retail purchases occur online today), improve product discovery for smaller merchants, and surface preferred brands based on user context rather than mass-retailer prominence. He said initial rollouts will be gradual but sees agentic shopping as an important new entry point for e-commerce that could benefit both large sellers and the long tail of merchants.
