At Bright Way () we’re living our mission to improve the financial well-being of hard-working Americans. Our goal is to transform the way our customers think about and use credit cards, rewarding good behavior in ways that truly add value, while providing experiences that empower and engage, even if that means challenging industry norms.
Operating as a startup and owned by One Main Financial, one of the largest and most successful personal finance companies in the industry, we launched our digital-first suite of credit cards in 2021 and have been on a high growth, fast-track ride of fostering innovative thinking to engaging and empower our customers ever since.

We’re not afraid to look to outside influences and create new frameworks.

Establish and enforce standards for rule authoring, documentation, testing, and maintainability
