Some folks squirm at mention of a woman’s period…not Arunachalam Muruganantham. Considered a madman and pervert by his community, he ignores his detractors and makes his dream—low-cost sanitary pads made by and for rural Indian women—a reality. Using manually operated machines, Muruganantham’s microbusiness model is focused on something more important than profits: providing sustainable employment, hygiene and emancipation to women who would otherwise go without. He’s a man with a million-dollar idea—except money has nothing to do with it. His goal is to make a livelihood, not to accumulate wealth; to operate at a human scale, not a multinational one. Menstrual Man is the inspiring story of a hero who rises above poverty and a lack of education to become a superstar social entrepreneur in the business of breaking cultural taboos and re-inventing the economic pyramid. Muruganantham is leading a movement, not a company. And it’s spreading.
