Products

We build for ourselves first.

Our own apps are where we try every idea, with our own money and our own users. Then the same team and the same standards go into your project.

And then we build for you.

Approach

Three phases. No surprises.

1Before we build

Discover

We map your goals, users and constraints. You get a written scope and a clear estimate.

2While we build

Build

Short cycles with working versions on your phone early and often, so you always see the progress.

3After launch

Launch & care

Store release, monitoring and long-term support. We stay after launch.

Principles

Integrity you can check.

“Deen” means a way of life. For us it means a few simple rules we keep on every project.

  • A clear estimate before we startYou know what to expect up front. No hidden costs, no surprise invoices.
  • No dark patternsWe don’t build tricks that push people into things they didn’t choose.
  • Privacy by defaultWe collect as little data as possible and follow GDPR from day one.
  • You own everythingThe code, the accounts and the keys are yours, always.
  • Honest adviceIf we’re not the right team for your project, we’ll tell you.
