Want to work in a group of 3-4 students to create a startup? In summer startup, you'll come up with an idea, develop a prototype, develop a pitch, and present your startup to a variety of audiences. You'll need to be totally committed to (A) working in a group and (B) self-teaching/self-learning new skills, e.g., new programming environments, business research, communication skills, etc.
Summer start-up projects have been running since 2015, challenging small teams to see a business idea from spark to prototype-and-plan. The projects are student-created and -driven, including learning the technologies involved and using them to develop a minimum-viable-product that captures a new idea.
