Description: Founded in 2006, Lending Club serves as ostensibly the most well-known and largest online peer-to-peer lending marketplace. The company facilitates personal and business loans, as well as financing for elective medical procedures, leveraging technology and a zerobranch infrastructure to drive costs down and charge borrowers lower rates. Having helped fund more than $18.7 billion in loans to date, the company itself doesn't assume the credit risk of the loans it helps sell, but simply connects borrowers and investors via its online platform.
