Peer to Peer portal Funding Circle has announced it will introduce a new risk tier that will allow the company to serve a quarter more of its U.S. small business loan applicants. Funding Circle connects business owners with investors facilitating loans up to $500,000. Announced during a presentation at LendIt 2014 in San Francisco, the new tier was designed for borrowers who have traditionally faced difficulty in obtaining a loan. It will also provide opportunity for investors who seek greater returns and diversification. The new tier will roll out exclusively in the U.S. this summer.
