Prosper is a platform that connects borrowers with individual and institutional investors. It allows people to apply for personal loans, which are funded by investors who earn interest on the money they lend. This peer-to-peer lending model aims to provide better rates for borrowers and attractive returns for investors. Founded in 2005, Prosper was one of the first companies to offer this type of service in the United States. The platform uses a credit scoring system to assess borrower risk, helping investors make informed decisions. Overall, Prosper seeks to create a more efficient lending process for both parties involved.
