B en Navarro is an American billionaire financier and the founder of Sherman Financial Group, one of the largest consumer debt buyers in the United States. After working at several financial institutions, Navarro founded Sherman in 1998. The company's primary business involves buying portfolios of defaulted consumer debt, such as unpaid credit card balances, from banks and other lenders at a steep discount.

Sherman Financial Group then attempts to collect on this debt, a business model that has been both highly profitable and controversial. The company has grown into a massive enterprise, and Navarro has diversified its activities, most notably by founding Credit One Bank, a major issuer of credit cards to subprime borrowers. In recent years, Navarro has also become known for his philanthropic activities in Charleston, South Carolina, and for his unsuccessful bid to purchase the Carolina Panthers NFL team.
