To stay in close loop with the MIT Entrepreneurship Center, entrepreneurial students join the MIT Entrepreneurship Society after graduation. Open to all MIT alumni, the E-Society is a community of people committed to supporting each other in entrepreneurial endeavors and further developing entrepreneurship at MIT.

E-Society members have a private email list and directory that enable them to seek and give help and resources to other members including helping identify funding sources, advice on mergers and acquisitions, sourcing job candidates, and general guidance for how to grow a successful high tech startup company. This grows the entrepreneurial alumni network, for which the MIT E-Society encourages every member to commit to being an active supporter and resource.

Each member also pledges to give back financial support to entrepreneurship at MIT at some financially well-off point in their entrepreneurial career. In return, E-Society members receive special VIP invitations to all MIT Entrepreneurship Center events and unique access to many MIT Entrepreneurship Center resources and contacts.
