Two early adopters of cryptocurrency, Tamas Kadar and Bence Jendruszak witnessed first-hand the damages fraudsters could cause to a business. The bitcoin exchange where they worked suffered constant and heavy losses in high chargeback rates. Couldn’t they find a way to reduce these attacks, or better yet, remove them altogether?

The question led them to investigate fraud prevention solutions. Unsatisfied with the offers on the market, they decided to set up their own. One that would combine powerful technology for data enrichment with light-touch, single API integration. One with a flexible business model and an intuitive admin panel, allowing businesses of all sizes to afford prevention and complete control.

A few years later, SEON was born. Since 2015, Tamas and Bence have successfully raised seed-round investment for their machine-learning system, but more importantly, proved the tech is solid enough to be trusted by renowned clients. Today, they help reduce fraud for a number of international companies such as KLM, Air France, Barion Payment and Eurobet. So what next for SEON? The company has its eyes firmly set on the future.

Aside from aiming to serve a larger number of clients, Tamas and Bence are currently working on blockchain integration into their solution. After all, it is a technology they know and understand, and the reason they became passionate about fraud prevention in the first place. And if their success with SEON is anything to go by, they sure have the engineering know-how and business sense to make it happen.
