About us
We dare to design the future of payments. Ratepay is energy and diversity and: custom-made state-of-the-art payment solutions. Established in 2009 we were a fintech before the word fintech even existed. Today we are the number one white-label Buy Now Pay Later payments provider in Europe handling over 2.5M transactions per month and we’re constantly growing.
We are where we are because we work together as one team. Because we got the freedom to execute ideas. And above everything: because we never stop improving. Here it is all about shared goals not about the big ego. We are dedicated pros (more than 250 of them) not cons. We embrace being courageous, committed and decisive, warm-hearted and having a will to win.
We have our origin in the heart of the payment scene and cover the whole value chain from integration support to the dunning process with a core of AI-based risk management. With us, you can integrate direct debit, instalments and prepayment. In other words: the favourite payment methods in Germany, Austria and Switzerland (the Dutch like it too). Located in the middle of Europe’s fintech metropolis (Berlin) we are proud to work with major partners such as Eurowings, Ebay and About You and hundreds more.
