About OnePay
OnePay is a consumer financial services app with an exceedingly simple mission: to help people achieve financial progress.
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? We have the backing of Walmart (a Fortune 1) and Ribbit Capital (a preeminent fintech investor), are deeply embedded with the distribution of the world’s largest omnichannel retailer, and have an industry-leading multi-product value proposition — all in addition to having some of the best people and talent in the industry.
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!
