The event is for everyone interested in new things from the world of Java and related universes! Conference schedule is a mix of invited and call for papers talks. We are working very hard to choose the most interesting technologies and solutions in order to show you the hottest stuff.

In the previous years we managed to gather over 2000 attendees. Almost all of them rated events' organisation and content very high. Interesting presentations, world-class speakers and unique atmosphere, all while keeping very reasonable ticket prices (we are doing our best to keep it low).

GeeCON is all about the community, it's organised for and by the community. During previous editions, we've hosted free community events like JUGs@GeeCON (2010), GeeCON Community Day (in 2011). We are very proud that technical User Groups from all over the world (including Poland, Italy, France, Belgium, Egypt, Brazil, Austria, Ukraine) are willing to work with us to improve GeeCON.

Let's move the Java world!
