Los Angeles based big data online lender ZestFinance has raised $150m of debt financing from New York's Fortress Group. The financing will enable Zest to expand its new lending arm, Basix, which launched in July and is aimed at borrowers with middling credit----targeting those who might not qualify for a loan from popular online lenders such as Prosper or SoFi. Former Google CIO and ZestFinance founder, Merrill, recognizes that the investment is an important vote of confidence for the online lender from a large institution.
