CCEx is a software development company with as current areas of activity: Information Security, Game Development and Artificial & Virtual Intelligence.
We do this by developing Free Software accessible by anybody anywhere for free (like in free beer), freely (like in freedom).
To do this we simply sell licenses of our software for commercial use, and release its code for free to individuals and non-profit organizations. Just like what many software companies have done or do currently.
It's a very viable model, if done correctly, and everybody should profit from it.
