Kiva.org is a really successful way of helping small business create jobs across the world via microfinance. They’re now celebrating their sixth anniversary.
You can visit their site, and check out small businesses and what kind of loans they need to expand. My focus has been the West Bank, though I’ve also made loans in places including Detroit. (I lived in the area for ten years.)
Note that Kiva’s different from donation websites because the money can be relent somewhere else after it is paid back.
A lot of people have helped out via Kiva, and one way to check it out is to view their recently released visualization which shows loans being made crossing the world.
