Tens of millions of Americans today are unbanked or underbanked, meaning they don’t have enough money in savings to cover a minor emergency. They pay too much in fees, don’t have access to credit at affordable rates, and have little ability to grow their wealth. OnePay’s vision is to create a single app for consumers to save, spend, borrow, and grow their money, bringing our mission to life with simple and accessible banking, credit, and payments products that deliver a best-in-class experience to millions of customers. Our products include:
-Checking and high-yield savings accounts
Domestic and international peer-to-peer payments
Credit Builder and credit score monitoring
Digital wallet / contactless payment solutions
Credit card program
Buy-now-pay-later installment loans at Walmart
Prepaid mobile service
Why do we have a right to win?

There’s never been a better time to build a category-defining business and there has rarely been a team better positioned for the opportunity. Join us!
