Ending Poverty: There's an Open Source App for That!
Rural Africa presents changemakers with intractable challenges across sectors, but one American investor, Grameen Foundation, believes it all comes down to access to information. Grameen Foundation has invested millions to develop mobile-phone applications that leapfrog over a lack of electricity, education, and income. Building on their legacy of leading-edge ideas, Grameen Foundation has evolved from funding microfinance to designing disruptive solutions to the kind of poverty that's most challenging to reach, in remote rural areas, and to the poorest of the poor. Since more people have access to cell phones than toilets in Africa, Grameen Foundation brings increased agricultural productivity, access to prenatal and infant healthcare, and a portfolio of financial services, to the poor--right into the palm of their hands.
