Jordan Casey
App developer
If ever there was a tech entrepreneur to make you feel like an underachiever, Jordan Casey would be it. Described as the youngest app developer in Europe, he has already founded two companies – Casey Games and TeachWare – launching his first game at the age of 12. Casey Games, as the name suggests, was focused on apps and games, while TeachWare developed a web-based application to help teachers manage their students’ information.
