Cascading layoffs that accelerated the decline · Fatal mistake: Built European Amazon aggregator on identical assumptions to Thrasio; collapsed identically when Amazon algorithm changed
Evaluating only SellerX’s profile at its peak — without knowing the outcome — the model ranked Unit economics as the #1 likely cause. Documented cause: Overexpansion.
Key Events Timeline
FUNDING
Raises €227M equity and debt round — one of the largest European raises for an Amazon aggregator. Acquires dozens of brands across Europe.
LAYOFF
Lays off over 200 employees as Amazon algorithm changes and rising interest rates collapse the aggregator model. Exits multiple European markets.
DOWN ROUND
In discussions for merger or acquisition. Valuation collapsed from estimated €1B+ to undisclosed fraction. Continues at dramatically reduced scale.

Documented cause
SellerX was Germany's — and one of Europe's — largest Amazon FBA brand aggregators, founded in Berlin in 2020 by Philipp Triebel and Benedict Landwehrkamp. The company raised approximately €500M including a €227M equity and debt round in 2021, buying dozens of Amazon seller brands across Europe. Like its US counterpart Thrasio, SellerX acquired brands at peak multiples in 2021 and then faced the same structural collapse: rising cost of capital made leveraged acquisitions uneconomic, Amazon algorithm changes hurt organic rankings, and integration costs exceeded synergies. By 2023, SellerX had laid off over 200 employees, exited multiple markets, and was in discussions for merger or acquisition. The company continues in reduced form.
Lesson
“Copying a US model to Europe does not diversify the platform dependency risk — it replicates it. SellerX and Thrasio failed simultaneously because Amazon changed one algorithm, everywhere.”
