Creating a Fraud Free World @SEON: The Story

Tamas Kadar, CEO and Co Founder and Bence Jendruszak, COO and Co Founder, launched their first venture, a crypto currency exchange during their final year of university. Weeks in, they were attacked by online fraudsters. 😮 They were forced to hack together a set of tools to instantly inform them if a transaction was genuine or not. They then pivoted to building a platform that can detect fraudulent activity instead and that is how SEON was born. 🤩

They knew they could not do it alone so they teamed up with Miklos Kiss CPO and Balint Dali, CTO to enhance the revolutionary platform. Since then, the journey has been unstoppable. 18 months in and we have grown from 18 to 155+ SEON Fraud Fighters, across Budapest, London, Austin and Jakarta. With more hubs opening up in San Francisco, Singapore, we are on a mission to create a Fraud Free World. We raised Series A in March 2021 and were featured in TechCrunch. We are proud to continue to grow at pace both in terms of helping the best online businesses and democratising fraud fighting.🔥🔥🔥
