Yellow Orange has been building digital products for more than two decades, combining software engineering, product design, and applied AI.
Flexible team, shaped around the problem
A compact network of builders, researchers, and domain specialists, mainly based in the Netherlands and assembled for each assignment.
Useful software for hard operational problems
We work where rules, data, people, and workflows meet: knowledge platforms, crew optimization, blockchain proofs, and other specific systems.
Public solutions
A few examples we can talk about publicly. Most of our work is built around specific teams, data, and operational constraints.
