This is the writeup of a session I delivered at both the Hong Kong Computer Society EASIG Seminar and Cloud Expo Asia. It’s about how, at PayMe, we started by creating an API product but realized our goal should have been to build an ecosystem instead. What is PayMe Wikipedia makes a decent job of explaining it: https://en.wikipedia.org/wiki/PayMe, although it’s a bit light on the products that are most relevant to this post: API and POS.
