Barcamp is a good way to get an overview of the start-ups. In Paris, the ones i’ve covered in earlier posts are The Tokeda Project and Moovement. The full list is here. Richard tells us more about some of the players here. Logistics : Meet at Yahoo! 17 rue Guillaume Tell 75017 Paris. On May 12th 14h00 until late at night or early morning next day. They won’t like it but i would say : just pop in (registration is full!).
If you can’t make it in Paris, may be you can in Portland, in Denver, in Ottawa, in Sheffield UK, and in many more places.
