Consumer behavior doesn’t change overnight, even when the technology is obvious. In this episode of Retailgentic, Scot sits down with Hamish Gunasekara to unpack why agentic commerce is inevitable, why it’s moving slower than the hype suggests, and why product data infrastructure, not checkout, is the real unlock.We cover:Why “fully autonomous shopping” is the wrong definition of agentic commerceWhy consumer habits change slower than technologyWhy global mega-catalogs don’t work (and never really have)How vertical AI shopping experiences can thrive alongside ChatGPTThe hidden trust and governance problem no one is talking aboutWhy product catalogs are the hardest unsolved problem in commerceIf you’re a retailer, brand, agent builder, or investor trying to understand what actually matters in the agentic commerce stack, this episode is foundational.Timestamps:02:39 Meet Hamish & the origin of Catalog04:55 From Afterpay to Cash App Commerce11:30 The Naya experiment & lessons learned14:24 How AI is changing discovery16:08 Why catalog data is broken18:30 Fundraising & early traction20:48 Who Catalog is built for23:20 Why global catalogs don’t work28:30 The agentic commerce stack33:40 Defining agentic commerce (correctly)37:30 Why vertical agents will win43:45 Trust, governance, and adoption44:51 Where to learn more👉 Connect with Hamish: https://www.linkedin.com/in/hamish-gunasekara/👉 Learn more about Catalog: https://getcatalog.ai/🧠 Want to stay ahead in AI commerce?

In this episode of Retailgentic, Scot sits down with Luca to unpack a research paper that blends academic rigor with real-world implications:“LLMs Reproduce Human Purchase Intent via Semantic Similarity licitation of Likert Ratings.”The paper, co-authored with Colgate-Palmolive researchers, explores whether AI can accurately simulate human reactions to product concepts, enough to replace or accelerate traditional consumer panels, which are slow, expensive, and hard to scale.This one goes deep, but in ways that any retail or AI leader should care about. Scot and Luca discuss:Colgate’s Challenge: How to test product concepts faster and at scale.Synthetic Consumers: AI models that react to products like human panels.Accuracy Breakthrough: Reaching ~73–74% agreement with real consumers.Fixing LLM Failure Modes: Why naive prompts don’t work, and what does.Bayesian Reasoning: Adding uncertainty so AI stops being confidently wrong.Smarter A/B Testing: Using AI to pre-screen ideas before running live experiments.Digital Clones: Future consumers earning money by sharing preference data safely.Simulated Populations: Matching real audiences for testing and predictions.AI isn’t just helping brands write copy or generate images, it’s beginning to think like their customers. If synthetic consumers continue to evolve at this pace, product development, A/B testing, and personalization may look completely different in just a few years.Timestamps: 03:00 — Luca’s background: Rocket Internet, HelloFresh, Lazada, Stitch Fix08:00 — How PyMC Labs was founded & why Bayesian modeling matters16:00 — Bayesian thinking explained in simple terms19:00 — High-stakes decisions & why probabilistic reasoning matters24:00 — Colgate’s challenge: testing product concepts at scale26:00 — How synthetic consumer panels work30:00 — Accuracy results: humans vs. AI (~73–74%)32:00 — Why naive LLM prompting fails (“mode collapse”)35:00 — How reasoning → scoring solves accuracy issues38:00 — Example: synthetic consumers evaluating PyMC’s own website redesign44:00 — How AI can pre-screen ideas for smarter A/B testing48:00 — Where AI cannot replace causal testing49:00 — Digital clones & monetizable consumer preferences52:00 — Future benchmarks, new LLMs & evaluation methods👉 Connect with Luca: https://www.linkedin.com/in/lfiaschi/👉 Learn more about PyMC Labs: https://www.pymc-labs.com👉 Check out the paper: https://arxiv.org/pdf/2510.08338🧠 Want to stay ahead in AI commerce?
