One is a gluten-free snack-food company. Another is a pest-control firm. They are two of the six members of Northeastern University’s first graduating class of start-ups.

Launched in a basement classroom, nurtured with the help of students, professors, and alumni mentors, these fledgling companies have matriculated through Idea, Northeastern’s accelerator program, which is distinguished by its management team: The incubator, which hosts about 80 start-ups, is run by students.

“We see this as a huge experiential learning lab,” said Dan Gregory, a Northeastern business school professor and Idea’s faculty adviser. “We want to build great ventures, but we really want to build great entrepreneurs.”
