Kiva lets you connect with and loan money to unique small businesses in the developing world.

By choosing a business on our website and then lending money online to
that enterprise, 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 monthly email updates that let you know about the progress
being made by the small business you’ve sponsored. These updates
include reports on loan repayment progress, photos of new capital
equipment, narratives on business growth and standard of living
improvements, and more. As loans are repaid, you will get your original
loan money back…."
