A survey of seven MIT science and engineering departments quantifies how many biotech startups have been lost to gender bias: 40. The study, which compared the relative proportion of female faculty members (22%) to woman-founded companies (10%), got its start at the 2018 Xconomy Prize gala. Nancy Hopkins—no stranger to measuring gender bias—told the story of a woman in venture capital who carried a list of 100 VC-funded Boston biotechs, 99 of which were founded by men. Hopkins’s KI colleagues Sangeeta Bhatia, entrepreneur and founder of Glympse Bio, and MIT President Emerita Susan Hockfield heard the speech and joined with Hopkins to brainstorm strategies for addressing this imbalance. Their conversation grew into the Boston Biotech Working Group, which carried out the survey and is spearheading several programs to boost the number of women biotech founders.
