The Polytechnique community is composed of networks and associations that enable entrepreneurs to meet and exchange ideas.
Startup Café organizes meetings between Polytechnique alumni who are now entrepreneurs, and students at the École interested in entrepreneurship. The group is run by young business creators who studied at École Polytechnique. Meetings are open to all, and take place on the Polytechnique campus. They are an opportunity not only for students but also for researchers, teachers and entrepreneurs to talk informally to participants.
X-start-up is the network of X entrepreneurs, bringing together Polytechnique alumni who have created a live business.
Cabinet Start up
The association Cabinet Start up encourages entrepreneurship among Polytechnique students. In March 2014, the group organized the first Startup Weekend at the X : participants had 54 hours to come up with a viable start-up project, from product design to the business plan.
