"Kiva lets you connect with and loan money to unique small businesses in the developing world. By choosing a business on Kiva.org, you can "sponsor a business" and help the world's working poor make great strides towards economic independence. Throughout the course of the loan (usually 6-12 months), you can receive email journal updates from the business you've sponsored. As loans are repaid, you get your loan money back."
This was very exciting to see!
What a great idea, implementation and outcome for this website that is already changing the lives of many entrepreneurs in the developing world. They seem to have a network of physical partners established in the countries where it operates that legitimizes borrowers personally which is a key part of what they do.
