Business Model
What each company does and how it makes money
Green Dot is a financial technology and banking platform that provides prepaid debit cards, checking accounts, and money movement services to consumers and businesses. It generates revenue primarily through interchange fees from card transactions, monthly account maintenance fees, and service fees from its business-to-business money processing operations. The company's key advantage is its extensive retail distribution network—with cards sold at over 100,000 retail locations—which creates significant scale and brand recognition in the prepaid financial services market.
Mastercard is a global payment technology company that operates a network connecting consumers, merchants, financial institutions, and governments. It generates revenue primarily from transaction processing fees—charging a small percentage of each payment volume—and from service fees for its data analytics, consulting, and security solutions. The company's moat lies in its massive two-sided network effect—the more merchants accept Mastercard, the more valuable it becomes to cardholders, and vice versa—creating a powerful ecosystem that's difficult to replicate.
American Express is a global payments and financial services company that issues charge and credit cards to consumers and businesses. It generates revenue primarily from discount fees charged to merchants — typically 2-3% of transaction value — and cardmember fees, with additional income from interest on revolving balances and travel services. Its key competitive advantage is its premium brand positioning and closed-loop network — which allows it to control both card issuance and merchant acceptance while collecting rich transaction data.

Both have compounded well over 10 years (MA: +515.7%, GDOT: -44.0%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.
