About Stefan ๐Ÿค“

Stefan Gaasbeek (aka Stefan XYZ) is a Dutch businessman, internet entrepreneur, domain investor, crypto enthusiast, and co-founder of Social Network Telfie.

He is a very creative, ambitious, and business minded person. Stefan launched his first internet business with his twin brother Erwin at the age of 15. Since 2004, Stefan has worked on many projects, some failed enormously, while others were a huge success.

At the moment Stefan is managing several internet projects, and works with his team on a new version of Telfie. Telfie is also launching a cryptocurrency later this year, that will be used on the new Telfie platform.
