To guarantee hassle-free transactions to our international clients, we're handling them through our payment provider Mangopay.
Mangopay is a branch of the French bank Credit Mutual and European payment service. They have recently been nominated as “Best E-payment solution in Germany”. :)
As a European startup, we are not allowed to accept payments directly and hence have to work with a payment provider that acts as a trust fund. The underlying reasons are anti-money-laundering efforts by the European Union, and you can read more about it here.
