It seems like a pretty sweet company. I'll have to look into them some more.
I'm currently building a comprehensive management system for my buddies company. Before, this we (wife and I) designed, implemented, and managed a content engine for the same company.
Are you getting involved at all with their service?
Thanks for getting back - these days there are rare German companies that are advanced in development and potential rising stars. In terms of involvement, I am approaching them but we have nothing fixed yet :-).
