The New Venture Competition, the annual student competition sponsored by Harvard Business School’s Rock Center for Entrepreneurship and Social Enterprise Initiative, has released a list of semifinalists who’ll compete under the “Social Enterprise” category.

This year, the Arthur Rock Center for Entrepreneurship, which oversees the NVC, had a record 69 teams enter the competition’s Social Enterprise Track. The preliminary round of judges selected 16 teams to advance to the semifinal round, which will further narrow down the list.
