Ally Financial Inc.
A digital bank and auto-finance leader, Ally Financial runs Ally Bank—the largest all-digital bank in the US—alongside auto loans and leases, dealer insurance, and loans to middle-market companies. It began life in 1919 as GMAC, the financing arm General Motors created because banks wouldn't lend on cars, then rebranded as "Ally" in 2010 to shake off its parent's shadow and become an independent, customer-first bank.
