Our take
Traditional banking hasn't worked for millions of Americans who are underserved or priced out of the system. High fees, minimum balance requirements, and tough credit checks create barriers that keep everyday people from building financial stability. Meanwhile, fintech startups are proving there's a huge demand for simpler, more accessible financial services. But most of these apps still focus on just one or two features, forcing users to juggle multiple platforms to manage their money.
OnePay is Walmart's all-in-one financia platform bringing everything together in a single app. Launched in 2021 through a partnership with Ribbit Capital, OnePay expanded after Walmart acqwuired fintechs Even and ONE in 2022. The platform now includes buy-now-pay-later and, through a new DriveWealth partnership, stock and ETF investing. On top of this, OnePay also serves employers with a B2B financial wellness suite to improve employee stability and engagement.
OnePay is already helping millions of consumers and has earned a 4.8-star app rating. And recently it announced crypto trading for Bitcoin and Ether, further expanding its offerings. With this momentum, the platform is really positioning itself as a true one-stop financial hub.
