Mastercard’s technology at the heart of Treezor’s international deployment

Based on a technological and commercial partnership with Mastercard, the collaboration between the two companies now extends to card transaction processing and Card Management System.

MPTS will enable Treezor to optimize card payments in foreign currencies and therefore easily open the path to globalization for the 40 neobanks and Fintechs that are Treezor’s clients.

“Mastercard’s ability to provide Treezor rapidly with the whole range of its value added services to reinforce the centralization of its payment processes on a unique platform for France and other European markets was a decisive factor in our choice to implement MPTS. Our ambition is to position Treezor’s platform among the best references in Europe” 

Eric Lassus, CEO, Treezor

“The strengthening of our partnership will contribute to improve Treezor’s agility and add new services to neobanks and fintechs. Treezor can count on Mastercard’s team support in both France and other European countries to accelerate its development in new geographies.”
