In this episode, Richard Hill sits down with Matthias Kleven, Head of Northern European Partnerships at Shopify, to unpack one of the biggest platform shifts eCommerce has seen in over a decade—the ability to buy directly from AI agents without ever leaving the conversation.

Matthias breaks down Universal Commerce Protocol (UCP), an open framework co-developed by Google and 20+ retailers that allows agents like ChatGPT, Google Gemini, and Microsoft Copilot to handle the entire buying journey—from discovery to cart logic to checkout—without redirecting to a website. For Shopify merchants in the U.S., this is already live. For non-Shopify merchants, the Shopify catalog is now open for the first time ever, allowing anyone to sell into these agentic platforms.

This isn't theoretical. It's happening now. And the implications for conversion rates, customer experience, and how merchants think about SEO and product optimization are massive.

Matthias explains why 50 million commerce-related queries happen daily on ChatGPT alone, how merchants can toggle agentic storefronts as channels in their Shopify admin, and why optimizing product catalogs, FAQs, and shipping details is now as critical as traditional SEO ever was. He also shares how UCP sits as a universal adapter layer on top of existing APIs and tech stacks—it's not a replacement, it's an accelerator.

If you're running an eCommerce store, managing a brand, or building strategy around the future of shopping, this episode is essential. The shift from keyword search to conversational commerce is here, and the merchants who prepare now will dominate the next era of online retail.
