Paul Groos · Managing Director
We started by building our own brand: GreenHec – phone cases, screen protectors, holders and charging cables. Every process we offer today, from sourcing and compliance to listings, ads, fulfilment and customer service, we first built and tested for ourselves.
Since 2026 we also bring partner brands to the marketplaces. Instead of charging for services, we buy the goods ourselves. That aligns our interests with yours: we only earn when your products sell.

Track record
From 3 to 6 marketplaces in two years
We started on three marketplaces in July 2024. Today we sell on seven marketplaces across Europe and through our own online shop.
Our own brand GreenHec – phone cases, screen protectors, holders and charging cables – is where we built and tested every process.
* Q3 24: started mid-July, so not a full quarter.
How we work
Numbers, not promises
Every decision is based on real sales data – from the trial order to the reorder.
Fair to our partners
We don’t undercut your prices and we don’t take sales away from your own channels.
Quality like our own brand
Your listings, service and packaging meet the same standard as GreenHec.
