There were great presentations and workshops. Especially the web 2.0 business model workshop gave some new hints and showed the success factors of startups. (updated later)
Here are the winners of the business plan competition:
1. Platz: Bluewalks (bluewalks.com)
2. Platz: Forsslund Systems (forsslundsystems.se)
3. Platz: Smaboo (smaboo.de)
I really like Bluewalks due to my hobby of city travelling.
