Hey, thanks so much for your comments - always love feedback. We've only announced the very beginning, there is a lot more that we have not commented on yet. We're surrounded by lots of brilliant people (not to mention Xavier Niel and I think we can all agree he knows how to build things) - it's not just me (Roxanne), don't worry :) Thanks again for your comments.
Many of the French universities have incubators, for some you do not need to be a current student but have a graduate or alumni in the founding team (for example, the Sciences Po incubator is like this.)
LeCamping is actually an accelerator, not an incubator.
The région IDF and Paris Développement also have an incubator, I think Paris Incubateurs is the name.
But if you are simply looking for mentoring and not necessarily a work space, you may also want to look into the Founder Institute program, which gives you access to mentoring and a great network through their weekly sessions.
