Kleinanzeigen, Germany's largest classifieds marketplace, has migrated its Secure Payment feature to Adyen, taking direct control of its payment processing, fraud prevention, and checkout development for the first time. The move replaces the previous setup with an in-house model built on Adyen's technical infrastructure, giving Kleinanzeigen full ownership of the transaction layer across its platform. (Adyen)
How Secure Payment Worked Before
Kleinanzeigen, launched in 2009 as eBay Kleinanzeigen, was acquired by Norwegian classifieds group Adevinta in 2021 and rebranded in 2023. Its Secure Payment feature, introduced in 2020, was built on Online Payment Platform (OPP), a Dutch marketplace payment specialist that handled escrow, KYC, buyer protection, and seller payouts. The model was functional, where buyers' funds were held until delivery was confirmed, and neither party needed to share bank details or email addresses. However, it meant Kleinanzeigen had limited visibility and control over a layer that sits at the core of platform trust.
What the Adyen Setup Delivers
The migration consolidates payment processing onto a single Adyen integration, replacing OPP as the intermediary. Adyen's fraud detection services, Uplift, dynamically detect fraud without relying on static, manual rules, enabling Kleinanzeigen to tune its risk management specifically for P2P marketplace behaviour. A redesigned checkout reduces the flow to a single click. Kleinanzeigen now controls how payment features are developed and can respond faster to EU regulatory changes, an increasingly relevant consideration for platforms operating in online commerce across European markets.
My Take
Adevinta has been explicit since the acquisition that Kleinanzeigen's ambition is to become a full transaction platform in Germany, not just a listings site. Controlling the payment layer is the necessary first step. What comes next? Since Kleinanzeigen, like other classified marketplace providers, is overwhelmingly C2C, where private individuals sell secondhand goods to other private individuals, its embedded finance journey is likely to look different from other marketplaces. Both embedded lending and banking are very unlikely (both require recurring business relationships that one-off C2C transactions simply do not create), and the focus will likely remain on improving the payment layer itself. Perhaps better buyer protection, faster dispute resolution, or deeper logistics integration.
