Estreem: the new benchmark for payment processing in Europe

Born from a strategic partnership between two major French banking groups, BNP Paribas and BPCE, Estreem is an independent fintech launched in February 2025. Its ambition: to become the leading sovereign payment processor in France, capable of operating at European scale.

In a payments sector undergoing profound transformation, Estreem positions itself as a disruptive player, combining security, technological agility and economic competitiveness. The objective is clear: to swiftly join the TOP 3 European payment processors.

Equipped with a next-generation platform, Estreem covers the entire card processing value chain, from software editing to operational management, relying on state-of-the-art cloud infrastructure. It supports all major payment schemes (CB, Visa, Mastercard) as well as new European schemes such as Wero.

Designed from the outset to reach beyond French borders, Estreem aims to become a pillar of European strategic autonomy in payments.

The 3“E”s of Estreem sum up its DNA: Excellence in technology, Expertise in the business, and a strong European vision.
