Rivero's story

Working in the payment industry for several years and experiencing the challenges in running payment operations, the co-founders decided to go on a journey to bring modern solutions to the market that enable payment institutions to reduce operational risks while improving process efficiency.  ‍ Rivero AG was founded in 2019 with the primary purpose of simplifying payment operations. The first product, Kajo (for scheme licence management), was launched in April 2020 with the first group of customers in Switzerland and later in other European countries. The second product, Amiko (for end-to-end digitization of fraud recovery and dispute management), was launched in March 2021, with a growing number of customers across Europe.
