The invention of the assembly line changed the way the automotive industry conducted business in the 1920s. To keep factories running smoothly, manufacturers needed auto dealers to buy vehicles in large quantities. To help dealers finance and maintain their inventory — now Ally Financial — opened its doors as GMAC, a division of GM, in New York City. For 100 years, Ally Financial has transitioned through many different business and consumer environments. Today, Ally Financial is an award-winning leading digital financial services firm, one of the largest full-service automotive finance operations in the United States, and an online-only bank with 10,000 teammates serving 9 billion customers. In 2021, Diversity Inc. recognized Ally Financial as one of the “Top 50 Companies for Diversity” and Forbes named it one of the “Best Employers for Diversity.” The company promotes diverse thinking to inspire new ideas, invests in emerging technologies, and constantly innovates and reinvents products and services to best serve its customer needs.
