17 MIT startups to watch


Sixteen teams took to the stage Sept. 10 for the 2021 delta V Demo Day, marking a return to the in-person startup showcase, as well as the tenth anniversary for the Martin Trust Center for MIT Entrepreneurship's premier event.

Demo Day is the culmination of the Trust Center’s delta V accelerator — the name comes from the scientific term meaning a change in velocity. The accelerator provides teams with entrepreneurship training, coaching and mentoring, and mock board reviews, as well as funding, office space, and prototyping tools. Notable alumni include Biobot Analytics, which is studying wastewater across the United States as a way to track COVID, and Spyce, a restaurant with a robotic kitchen, which was just purchased by salad chain Sweetgreen.

Speaking to the audience in the Kresge Auditorium on MIT’s main campus in Cambridge, Massachusetts, the Trust Center’s managing director Bill Aulet pointed out that the institute has programs to solve problems in science, technology, design, and management. Why, he asked, would it also need entrepreneurship programs?

“Entrepreneurship gets you to figure out what you can do, and make a difference,” Aulet said, later adding, “There’s no fear about attacking problems here, and I love the problems we’re attacking.”

The problems many of the 2021 teams are attempting to solve reflect the challenges created in the past 19 months — a registry for unpaid family caregivers, platforms for monetizing online content, and a “vaccine” for crops.
