The New York Times:
D.light, a company cofounded by Sam Goldman, who spent four years in the Peace Corps in Benin before earning a master’s degree in business from Stanford University, is an example. Mr. Goldman started D.light with the mission of replacing millions of kerosene lamps now used in poor, rural parts of the world with solar-powered lamps.
Having used kerosene lamps himself while living in Benin, Mr. Goldman learned firsthand of kerosene’s problems — it is expensive, it provides poor light and it is extremely dangerous. When the son of his West African neighbor nearly died after suffering severe burns from spilled kerosene, Mr. Goldman said he realized he wanted to create a venture to solve both the social and economic problems caused by these lamps. His time in Benin also convinced him, he said, that only as a business could a project become large enough to reach the great number of people who use these lamps as their primary source of light.
“We could have done it as a nonprofit over a hundred years, but if we wanted to do it in five or 10 years, then we believed it needed to be fueled by profit,” he said. “That’s the way to grow.”
