Key Themes at SXSW 2026 with Omnicom's Greg Brown

·51 min·4 clips

Greg's core SXSW finding: an AI agent can recommend a detergent, compare prices, and add it to a cart without the consumer ever visiting a brand page — and Flywheel data shows $100 ROAS from sponsored ads inside Amazon's Rufus assistant.

The conversation starts in familiar CPG Guys territory. After the formal show opening and easy co-host banter, the discussion turns to South by themes around commerce, search, and artificial intelligence. Walmart becomes the pressure test. The host compares Walmart’s openness to AI agents with Amazon’s Rufus and tighter control of the customer journey, then asks whether Amazon’s confidence is a strength or a risk. Greg Brown does not crown a winner. He treats Walmart and Amazon as two live experiments, with major retailers still working out how AI discovery will change commerce. Target comes in as a mixed example. Brown also brings up Cloudflare CEO Matthew Prince’s South by comments about the internet after search and the different retailer models now being tested. The advice is practical, not showy. For CPG brands, the job is not to pick one platform’s version of the future and build only for that. The shaky part is the pace of change. Brown argues that brands need to stay platform agnostic and LLM agnostic because model capability and retailer strategy can move quickly. A leading model or retail approach today may not hold that lead for long. Betting on one retailer, or optimizing around one LLM, leaves a brand exposed when the ground is still shifting. The tone stays measured. The host gives Brown room to compare Amazon, Walmart, and Target without turning it into a scoreboard. The useful signal is flexibility: brands need discovery and brand equity plans that can stretch across Amazon search, Walmart’s agent-facing platform, and whichever AI interface gets traction next. The excerpt still carries the show’s trade-show rhythm, with branded setup, personal banter, and a legal close, but the strongest clip is the middle section where AI commerce turns into a brand-readiness problem.

A practical map for brands trying to stay visible as AI rewires retail discovery.

Greg Brown lays out a clear case for how CPG brands should think while Amazon, Walmart, Target, and LLM-driven discovery all shift at once. The practical lesson is simple: do not lean on a single platform, do not assume today's hierarchy will last, and build brand equity that…
