Alex Leutgöb is CTO & Co-Founder of FELGO GmbH (previously called V-Play). Equipped with a business and technical background Alex specialized in mobile app development in 2008 when the first app store launched. Since then he published several apps for customers reaching from small companies to multinational enterprises. With a profound knowledge for the mobile platforms iOS, Android, BlackBerry, Windows Phone, Symbian and MeeGo his apps were downloaded more than a million times. Because of this variety of platforms, he began to evaluate several possibilities for cross-platform development, which finally led to switching his focus on cross-platform mobile app creation with Qt and QML in 2011, when the Felgo framework was born.
