Microfinance site which allows you to invest in African business, undercutting the extortionate interest rates of local loansharks (up to 40%), and getting (if you want) a very competitive (albeit risky) rate yourself (I think Im averaging 8%).
Basically borrower chooses a sum, and rate they are willing to pay, and joe public bids on it, under cutting each other etc – sort of like on ebay… at the end of the bidding, the borrower gets the money at the lowest exchange rate bidded – on average 11ish%
Just chucked 30Euros in… very addictive stuff!
