ebusiness models seem to be matured enough to get some serious scientific coverage. I discovered a great resource recently. Tobias Kollmann, one of the founders of Autoscout24.de the car exchange that has recently been acquired as a part of a group deal by T- Online is also professor in Kiel. The departement is focused on ebusiness and eventures. He takes his research serious and has published a row of good articles and books. He especialy covers funding, research, marketing for different business models such as mobile commerce applications, marketplaces and digital content models. His papers are pretty interesting (unfortunately in German only):

• This paper has some great info how to select and refine the business model for your start-up.
• Another one shows some interesting case studies for venture backed start-ups.
• This one is a great starter's guide to a venture transaction.
• And this one has a nice classification of start-ups, helping to determine which one might thrive or not.
