Stripe

Stripe makes money by taking a small fee every time a business uses its code to accept a credit card payment online. They give startups a “magic” piece of code that lets them start taking money in minutes. They won by making their code so easy for programmers to use that they didn’t have to talk to old-fashioned banks. Their secret is being the “invisible engine” inside millions of new internet companies, making it very hard for them to ever switch to a competitor. They use Code Leverage to run an Infrastructure model distributed via an API.
