Why Felgo

As the only company in Europe and America, Felgo is a Qt Service & Technology Partner, focusing on Qt product development and extending Qt to new areas.

Felgo is a team of more than 20 people, working with Qt for more than 15 years.

As the creator of the Felgo SDK, we bring a complete view for product development and product team needs. Compared to consulting companies, we think value-based, not in time units or sales cycles.


Back in 2012 and long before the Qt 5 release, Felgo (former V-Play) was the first company that brought production-ready Qt app development to iOS and Android. For that, we combined an own OpenGL renderer with Qt 4.8 and launched the well-known Felgo SDK (former V-Play Engine) for mobile apps and games.

Today, Felgo gained profound knowledge in many fields of application and is thriving to solve new challenges with its partners and customers.

Felgo holds courses on programming for several Austrian universities, including the University of Applied Sciences Upper Austria and Salzburg University of Applied Sciences. Felgo also actively works on scientific research programs with Vienna University of Technology and Johannes Kepler University Linz.
