Thanks to Jean Derely for improving this list on and on.

In case you do not know about it, the Beta Group is the largest Internet & Tech entrepreneurship networking event in Belgium, with about 350 attendees in each of its monthly meetups. The event consists of a pitch slam with six startups showcasing their products, short requests and announcements from the audience (the live tweets), and lots of networking over free warm beer. A must.

Disclosure: I am a member of the Beta Group's council, and proud of it!
