What is "perkstreet"

PerkStreet Financial was an American-based virtual bank that offered checking and debit card accounts with cash-back rewards. The company was founded in Boston, Massachusetts in November 2009, and was led by former Capital One executive Dan O'Malley. With no bank branches, PerkStreet Financial had low operating costs. However, a cash-back rewards scheme that approached 2% for some debit card accounts turned out to be unsustainable, and contributed to the company's closure in 2013.
