Richard Branson, the billionaire entrepreneur, has just launched a new venture: Virgin Money. Like Prosper.com, it's a platform for person-to-person loans. The difference is that Virgin Money is designed to manage the small loans people get from friends and family. The idea is that people are constantly taking on loans for education, house downpayments, and their small businesses from people they know--and that an intermediary administrator will lower the default rates and preserve relationships. On the Virgin Money website, there's a feature specifically for small business loans. Branson says that a loan from his aunt kept his first business afloat during a rough patch. Have you ever borrowed from a friend or family member to grow your business? Do you think you'd use a tool like this one? You can share in the comments!
