About D4N

D4N is a software studio based in Derbyshire. We design and build websites, web applications, and iOS apps for businesses across the East Midlands and the UK.

We keep things simple. No account managers, no layers of process. When you work with D4N, you work directly with the person writing your code. That means faster decisions, fewer misunderstandings, and software that actually does what you need.

We specialise in three things: professional websites that generate leads, custom web applications that run businesses, and native iOS apps published to the App Store. We choose depth over breadth — we'd rather be excellent at a few things than average at everything.

Every project starts with understanding the problem. We ask questions, listen carefully, and build solutions that fit — not off-the-shelf templates with your logo swapped in. The code is clean, the design is thoughtful, and the result is software you can rely on.
