Dunderline B.V.

An independent software company
in Amsterdam.

Dunderline designs, builds and operates its own digital products — from first sketch to the app stores. We keep the company small on purpose: careful engineering, considered design, and software we are happy to run for years.

The company is registered in the Netherlands as Dunderline B.V. (Chamber of Commerce / KVK 78680220), based at Herengracht 551, 1017 BW Amsterdam.

What we do

  • Product engineering

    Native iOS and web applications, built and maintained in-house.

  • Design

    Interfaces that stay out of the way — typography-first, fast, accessible.

  • Operations

    We run what we ship: infrastructure, analytics and support under one roof.
