Zopa is a UK-based company providing an online money exchange service, allowing people who have money to lend it to those who wish to borrow, instead of using savings accounts and loan applications at traditional banks. The process is sometimes referred to as peer-to-peer lending. The name, Zopa, stands for "zone of possible agreement", a negotiating term identifying the bounds within which agreement can be reached between two parties.
