Who is Marie-Claude Nadeau
Senior partner at McKinsey and a global leader of the firm's payments work, based in San Francisco. She is a leading voice on how agentic commerce reshapes authentication, fraud, subscriptions, and top-of-wallet dynamics as AI agents begin transacting on consumers' behalf.
These experts look further ahead: as AI agents begin to compare, decide and even purchase for users, the entrance to commerce shifts from "humans clicking links" to "agents reading data." This is the layer after GEO. Their recurring focus areas include: Payments, agentic commerce risk, McKinsey.
What GEO / AEO practitioners can learn from Marie-Claude Nadeau
- **Product data becomes the fuel**: structured, accurate, machine-readable product information decides whether your items enter an agent’s consideration set. - **Trust and rules**: governance of payments, liability and authorization determines whether an agent dares transact with you on a user’s behalf. - **Agent Experience (AX)**: after UX, making AI agents understand and choose you efficiently becomes the new discipline.
**GEOly angle**: Payments angle: delegated authorization and know-your-agent infrastructure.
What it means for brands going global
For DTC and ecommerce brands going global, agentic commerce is both threat and opportunity: the sooner you shape product data, reviews and trust signals into a machine-readable, trustworthy form, the more likely you are to be chosen in agent-led shopping.
