Grameen Bank started out as a micro-credit organization in Bangladesh, making small loans to poor women so that they could start businesses. They proved that very small loans paid back regularly in small amounts could make a huge difference. From their website:
“Grameen Foundation USA is empowering the world’s poorest people to lift themselves out of poverty with dignity through access to financial services and to information.
“The Grameen Technology Center is working to eliminate poverty by leveraging the power of microcredit and technology.”
