Kiva, a non-profit website that allows you to lend as little as $25 to a specific low-income entrepreneur across the globe. You choose who to lend to—whether a baker in Afghanistan, a goat herder in Uganda, a farmer in Peru, a restaurateur in Cambodia, or a tailor in Iraq—and as they repay the loan, you get your money back. Here's the Kiva about page.
I've been a member of for a while now. In fact, my daughtter and I started her micro-loan fund a few years ago. Since she started with $100, Maddy's lent to 33 different entrepreneurs and groups around the world and her fund is $500 or so. She re-invests the money with new entrepreneurs as the loans are repaid.
Once you're a part of the team, you can choose to have a future loan on Kiva "count" towards our team's impact. The loan is still yours, you choose who you loan to and repayments still come to you—but you can also choose to have the loan show up in our team's collective portfolio.
If you'd like to join our lending team we'd love to have you. We'd love it even more if you were to blog/post/tweet/invite your friends. For $25 you can help change someone's life.
