Stripe really did come about because we were really appalled by how hard it was to charge for things online.

When a country doesn't have a good economic infrastructure, that harms the country. With Stripe, the idea is that by providing better infrastructure, by linking the Internet economically, by making it easier for these online businesses to exist, it'll make the web better.

Auctomatic was a compressed start-up experience, going from start to launch to acquisition in under a year. We spent a long time building the product before getting our first customer, whereas with Stripe we made sure we had paying customers from the very start.

With Stripe, people who previously operated online or offline in a very limited capacity now have all the tools to work like a real online business. That's a very valuable thing.

Help each user personally. Sure that won't scale to a very large size, but when a startup is just starting out, it really helps you have an advantage as a small and nimble company.

I think a lot of people learn to code messing around with things while in secondary school. And for me, it started up as a hobby and a plaything, and I just became more curious over time.

In the desktop world, you could build a successful business where a consumer only came back to you once or maybe twice a year. I don't think you can build that kind of business on mobile. You need higher frequency, or otherwise you fall off the home screen and the user never comes back.

Our idea with starting Stripe was to build better payments technology for people building things on the web.
