Products

Things we've built ourselves: an app for everyday life, a tool for developers, and a book that teaches what we learned building them.

Vennie remembers what you hold, from food and bills to documents, and reminds you before anything runs out, falls due or expires. You can join the waitlist for the Android beta.
Dartform shows your Dart backend on a canvas, so you can see its models, endpoints and relationships without digging through code.
The Secure Flutter Handbook follows a developer through the security mistakes most Flutter apps ship with, across 12 chapters and a checklist to run on your own app.

Engineering Residency

Where we teach how we build. Project-based Flutter courses built around a real app, then real production problems to prove you can apply what you learned.

Project-based Flutter and Dart courses, each one building a real app from start to finish
Case Files: a real production bug every week, to diagnose from the evidence before you see the answer
A Recall Check with every course, and a free Beginner's Path if you're starting from zero

Builder Pipeline

Our work for businesses, kept separate from the teaching. We learn how a trade works first, then build the software it's missing.

Every product is already built and working, so your business can start using it straight away.
You get a one-week trial, so you can see it working before you commit to anything.
If you're stuck on a decision, you can book a call with the studio to talk it through.
