I would add: Stripe might build this for themselves, and Apple might one day provide a native API. But there is also a good chance that they buy this tiny YC startup instead - gets them two former Uber engineers and an instant working API. Another credible path to exit is to sell to a dumber, slower company - like Visa. Fraud is a huge issue and big companies in the payment space are always hungry for pragmatic solutions like this.
