OnBuy, the UK’s fastest-growing online marketplace, has launched across 12 European markets, opening registration for retailers in Germany, France, Spain, Italy, the Netherlands, Belgium, Austria, Greece, Finland, Portugal, Ireland and Slovakia.
The expansion cements OnBuy’s status as one of Europe’s fastest-scaling tech businesses, they say, offering retailers a fairer, more profitable way to sell online and giving consumers a credible alternative to US giants Amazon and eBay.
The move builds on a landmark year for OnBuy, which earlier acquired iconic British retailer Comet. The acquisition highlights the company’s ambition and growing presence in UK retail.
Early signs point to huge demand. OnBuy’s European beta activity has already delivered 308% sales growth and a 40%+ compound monthly growth rate, highlighting the scale of opportunity for sellers who join now. Expansion into a further 8 markets is already underway, putting OnBuy on track to be live in 20 countries by the end of 2025.
The company forecasts an additional £100m in Gross Merchandise Value (GMV) and at least 5 million new customers from its EU rollout in the next 12 months, with eyes on a total GMV of £1bn within the next 3 years.
Retailers across Europe are calling out for a marketplace that truly supports them. OnBuy is different – we don’t compete with our sellers, we champion them. Our model creates higher margins for retailers, more choice for customers, and a level playing field that the industry has been missing.
Europe’s e-commerce market is enormous and the appetite for change is clear. With our growth momentum and seller-first approach, we’re building a challenger marketplace that’s reshaping how retailers do business.– Cas Paton, CEO and Founder, OnBuy
A key driver of OnBuy’s success is its industry-first cashback programme. As the only marketplace worldwide to offer customers instantly redeemable cashback on every purchase, which can be spent immediately onsite or withdrawn, OnBuy has redefined loyalty. In the UK, this model has delivered over 50% repeat purchase rates, driving stronger sales and customer retention for retailers.
To lead its continental expansion, OnBuy has appointed Marie Dauphin as Head of Sales, who is building localised teams to recruit thousands of new retailers and establish strategic partnerships across logistics, affiliates and e-commerce platforms.
For retailers, the benefits are clear:
- Fast access to millions of European shoppers
- Clear fees and transparent policies
- Automated tax engine for easy cross-border selling
- Cashback-driven loyalty that boosts repeat sales
