## At a glance
- 8x: revenue growth since the opening months
- 8 countries: DE · IT · FR · ES · NL · BE · PL · UK

## Markets live
DE, IT, FR, ES, NL, BE, PL, UK

## Marketplaces live on
Amazon, Zalando, Bol.com

## Challenge
X-Bionic sold on Amazon vendor-only, supplying the marketplace as a wholesaler, which left the selling price and the buy box outside the brand's control. On Bol.com only a fraction of the range was listed. Worst of all, seasonal collections went live late, which is fatal for a brand built around seasons, while other sellers took the buy box from the official listing.

## What changed under Operator One
- Operator One became Merchant of Record, the legal seller across Europe, so pricing and listings came back under the brand's control.
- The vendor dependency was unwound: the brand stopped accepting vendor orders and addressed its distributors, and O1 cleared improper sellers off the buy box.
- The operation went live in about two months, starting with Germany and Italy, then rolling out collection by collection with each new season.
- The range expanded beyond Amazon onto Zalando and Bol.com, reaching a fashion audience Amazon alone does not.
- Day-to-day marketplace management moved to O1, freeing the brand's internal team.
- X-Bionic keeps ownership of its inventory and sets its own pricing strategy throughout.

## Outcome
X-Bionic trades as the seller rather than the supplier, across eight European markets and three platforms, with revenue several times its opening months.

## Who this applies to
If a vendor account has taken your pricing and your buy box, or your seasonal range never reaches the marketplace in time, the fix is structural rather than tactical. Book a call to see what moving to a seller model would look like for your range.

## Story
From supplying a marketplace to owning the storefront X-Bionic makes high-performance sportswear: technical apparel designed around body temperature and built in seasonal collections. It is a brand with genuine engineering behind it. On the marketplaces, none of that was showing. The problem X-Bionic sold on Amazon vendor-only. In that model the brand supplies the marketplace as a wholesaler, and the marketplace decides the retail price and controls the buy box. The brand had no lever over either. On Bol.com, only a small fraction of the range was even listed. The deeper damage was seasonal. A brand built around collections needs each season live when the season starts, and X-Bionic's were going live late. Meanwhile other sellers kept taking the buy box away from the official listing, so buyers were often not buying from the brand at all. What Operator One put in place Operator One became the Merchant of Record, which made O1 the legal seller across Europe and brought pricing and listings back under the brand's control. X-Bionic keeps ownership of its inventory and sets its own pricing strategy. The vendor dependency then had to be unwound. The brand stopped accepting vendor orders and addressed its distributors, and O1 cleared improper sellers off the buy box. The first markets, Germany and Italy, were live in about two months, and the rollout since has run collection by collection, in step with each new season. The range also moved beyond Amazon. Zalando and Bol.com opened a fashion audience that a single marketplace does not reach, and day-to-day marketplace management moved to O1 entirely. Where the brand stands now Eight European markets live across three platforms. Revenue several times what it was in the opening months. A full multi-season range live, with collections publishing on time. Buy box and pricing control recovered from the vendor model.
