I invested with them on the recommendation of two friends who've been with them for a couple of years. Basically they do what banks did 50 years ago. They take your money and they loan it out to people. No dodgy financial services, just simple loans. You don't have the safety of government guarantees if they go bust, but unless the economy suddenly tanks REALLY badly, and there are lots of defaults on the loans, you should be fine. The risk is spread because you only have a small (£20 or £50) slice of any one loan. This should be part of a portfolio of investments. I'd call it pretty medium risk.
