I wanted to find out more and simply called them - nice people, great concept !
Actually you can get much more than "just" platform marketing (which is 50.- € per aircraft and month - you were right).
They also offer a web based flight management system for daily ops and they give online presentations and free trials for this. Plus you can get your own interactive booking engine for your fleet on your webpage - the guy even said, they would customize this "Iframe" totally to the looks of your website.
And then they are also offering flight support services...
If you are a software user AND a flight support customer, the software provides seamless communication between you and their flight support !
Looks like somebody invested some thoughts into what the industry needs...
