The capstone event of the HBS's expansive offerings in entrepreneurship, this year's competition attracted 150 Harvard MBA candidates as well as students from six other Harvard graduate schools.
In addition, HBS graduates from 17 HBS alumni "hub" clubs worldwide participated in 14 regional competitions.
As part of the finale programme, a member of each venture delivered a 90-second pitch to the audience, leading to an electronic crowd vote.
Over the course of the entire competition, which began last fall, more than 200 judges and mentors took part.
Alumni winners were chosen by an online crowd vote by other HBS graduates around the globe, HBS students, and a panel of judges in three categories - most innovative, greatest impact, and best investment
