UK-founded cashback marketplace OnBuy, has accelerated its European expansion, launching eight new markets across Sweden, Norway, Denmark, Poland, Hungary, Romania, Czech Republic and Switzerland. The move brings OnBuy’s total European presence to 21 countries, giving UK retailers fast access to millions of additional customers.

The expansion follows strong results from OnBuy’s first 12 European markets, which have delivered 152% quarterly sales growth and a 300% increase in average monthly site visits in the second half of the year. The performance highlights a clear shift in retailer behaviour across Europe, as brands increasingly favour marketplaces that support, rather than compete with, the businesses that sell on them.

OnBuy’s model, centred on non competition, transparent fees and instantly redeemable cashback on every purchase, has resonated strongly with both customers and sellers. The first phase of expansion saw swift adoption from returning buyers, giving retailers quick traction in new regions.

Early indicators from the second wave are strong. During beta testing, the newly launched markets delivered a 374% quarterly uplift, signalling significant appetite for a marketplace that protects retailer margins while delivering clear value to shoppers.

Across Europe, retailers are looking for new ways of doing things. They’re tired of marketplaces that compete with them, squeeze margins or move goalposts. OnBuy is proving that a different approach works, which is clearly reflected in the growth we’ve experienced.

OnBuy is the only marketplace giving customers real cash rewards on every purchase. It boosts repeat purchases, grows lifetime value and gives sellers a competitive edge from day one, which is something retailers simply don’t get anywhere else.

This new phase of expansion brings us closer to a truly pan-European marketplace built on fairness, transparency and growth. For retailers, it’s a chance to establish themselves early as we continue reshaping the ecommerce landscape.
