two20 is a software development company. We build native iOS applications in Swift and SwiftUI, web applications in TypeScript, and the platform layer that sits underneath both — authentication, payments, invoicing, transactional email, scheduled work.

Most software fails after the demo. It holds together in a walkthrough and then falls over the first time a real customer touches it, or it runs fine and becomes unmaintainable the moment the people who built it move on. We build for the part that comes after.

The work runs in three stages. Scope produces a written design document: what gets built, what deliberately does not, and what it costs. Build ships in waves, in your repository, on your accounts, so you see it running long before it is finished. Hand over means documentation, access, and a system you own outright.

We stay on to run it only if you want us to.
