Rebtel became a favourite of people making international calls by dropping their costs by up to 98%. But taking payments online opened them up to new waves of transaction fraud. Head of Operations Daniel Martinez sat down with us in Rebtel’s Stockholm office to talk about how the company started, fraud schemes they stopped and their favourite SEON teammate! SEON x is a series where we hear from SEON customers, partners and collaborators about how they built and grew their companies and what they contribute to the fight against fraud. This series is brought to you by SEON. Where every day we help businesses protect themselves and you from fraud. https://seon.io/ https://twitter.com/seon_tech
