Episode notes
Founding Story Packing Flip-Flops By Hand
- Robert Gentz started by selling flip-flops on FlipTops.de and personally packed about 20 orders a day during launch.
- That hands-on early customer contact taught them why people bought online and fueled their initial investor pitch.
Flywheel Built From Specific Shoe Searches
- Zalando's growth came from a flywheel: scale inventory around specific searches, convert more traffic, expand brands, categories, then geographies.
- Starting with niche shoe searches (model + size) let them build selection that later converted broader brand and country demand.
Zalando's B2B Fulfillment For Brands Like Next
- Zalando launched a B2B vector that sells its logistics and software to brands, letting them run e-commerce from Zalando's infrastructure.
- Example: Next uses Zalando's European fulfillment footprint to service its continent-wide orders.
