One.app provides a digital banking platform that allows users to manage their finances through a mobile app. While it is not a bank itself, it collaborates with Coastal Community Bank to offer banking services, including a debit Mastercard®. The app caters to a wide range of clients, from individuals to small businesses, seeking a convenient and cost-effective way to handle their money. One.app stands out in the fintech market by offering a high-yield savings account with an Annual Percentage Yield (APY) of up to 5.00% on balances up to $250,000, which is significantly higher than typical savings account rates. The company generates revenue through interchange fees from merchants when customers use their debit card, and it provides additional benefits such as early direct deposit, cash back at Walmart, and overdraft protection. The goal of One.app is to enhance the financial management experience for its users while helping them grow their savings.
