One.app is a fintech platform that provides a digital banking experience through a mobile app and a linked debit Mastercard®. It does not issue its own bank licenses but partners with Coastal Community Bank to offer banking services. Users can manage money, earn a high-yield savings rate (APY up to 5.00% on eligible deposits up to $250,000 per year), and access features like instant payments, direct deposits that can arrive up to two days early, 3% cash back at Walmart (up to $50 per year), and up to $200 in overdraft protection. The app generates revenue mainly from interchange fees merchants pay when customers use the debit card. One.app targets individuals and small businesses seeking a convenient, low-cost way to save money and handle everyday transactions without monthly fees. Its goal is to simplify digital banking by offering strong savings returns, quick money movement, and practical perks through a mobile platform.

Is Auto Sales The Next Amazon-Walmart Contest?

While Walmart does sell and even buy cars through its Carsaver partnership, the company still relies on third parties to handle the bulk of the transaction process. This leaves an opportunity for Amazon to take a more direct approach, leveraging its vast ecosystem and tech-driven conveniences to elevate the car-buying experience
