While others are keeping us healthy: Daniel Yu’s Reliefwatch keeps pharmacy and clinic shelves stocked in developing countries with little more than a phone call. Anoop Jain’s Sanitation and Health Rights in India builds toilets for people in rural India while simultaneously supplying those communities with clean water, and Spencer Penn and Morgan Snyder’s Sweet Bites keeps kids’ teeth clean with a simple sugar-free gum.

This year’s group was put together by Emily Canal and myself from research and online nominations, and was selected by our returning judges: Jean Case, cofounder of the Case Foundation; Cheryl Dorsey, president of Echoing Green; Randall Lane, Editor of FORBES; and one new addition, an alum of our inaugural 2012 Social Entrepreneur list, Hugh Evans, cofounder of the Global Poverty Project.

And now, meet the rest of the group that will be making our world a better place to live, in 2016, and for decades to come.
