Because of the shortage of coders, big french consulting companies (Atos, Cap Gemini, ...) hire since decades graduates from every domain more or less related to science/technology and give them a six months training (in the best case) before sending them to the clients.
So I'm not that surprised that such a school will be successful as long there is a coder shortage. When the next bubble blows, these graduates will probably be the first to be layed off.
