The Junior Enterprise movement, born in France 52 years ago, is now expanding all over Europe and the World. it's composed by a network of student associations that offer consulting services to companies and privates. Junior Enterprises bridge the gap between students and the business world by allowing them to come in contact with companies early in their academic careers. They Provide a fertile ground to test new ideas and to take the responsibility of pursuing them, creating an environment where students can put into practice what they have learned and keep learning from every new challenge. Junior Enterprises are an opportunity, for both companies and students, to collaborate on new projects together. The goal of this talk is to present the junior enterprise reality at Politecnico di Milano and discuss opportunities created for both students and companies.
