In this episode of Marketplace Masters, Paul Sonneveld is joined by Gregor Leopold, CEO and founder of Global AMZ in Munich, for a practical walkthrough of the first 90 days after taking over an Amazon vendor account. The brief was deliberately specific: not top-line strategy, but sequence. What do you do first, and what comes after?

Gregor starts with the audit he insists on for every client, including the ones convinced everything is already running well, and the things it consistently uncovers: high-volume ASINs turning no profit, duplicated listings, missed reimbursements, and advertising KPIs that look excellent because the spend is sitting on branded keywords. From there, he walks through the sequence: pull the data, run the 80/20 on both your best and worst ASINs, then work the catalogue and the ad audit in parallel.

They also dig into why Gregor argues Amazon is now a media platform with a store attached rather than the reverse, and why that makes catalogue work ten times more important than it was five years ago, now that AI models and search engines are reading your product data. Plus the uncomfortable internal conversations, the "little kingdoms" inside mid-sized and large brands that cost them double and triple investment, why ROAS is interesting but not the most important number, and how to hold your ground when Amazon tells you a product has gone CRaP.

If you've inherited a vendor account and don't know where to start, this is your running order.
