About

The exact point of the solution

CTN Software is a software development and consultancy firm founded to turn complex business processes into simple, fast and reliable software.

Our story

Working on enterprise software across many industries, we kept seeing the same picture: businesses were either stuck with off-the-shelf packages that didn't fit, or wrestling with late, undocumented software that nobody dared to touch.

We founded CTN Software to change that. Our goal is to be a technology partner that understands the business goal, builds the right architecture, writes clean code and stands behind what it delivers.

Our expertise is the Microsoft .NET ecosystem: C#, ASP.NET Core, Blazor, Entity Framework Core, SQL Server and Azure. With these, we build long-lived, scalable systems for organisations of every size, from small businesses to enterprises.

Experience

A 9+ year enterprise journey

We bring experience from business-critical systems in energy, insurance and IT to your project.
