About

A studio built by someone who has run the systems.

UnoArch is a software studio founded by a Danish enterprise architect. We build platforms, connect systems and advise on the hard technical calls, with the judgment of fifteen years inside enterprise IT and the speed of a small, senior team.

Portrait of Stig Sörnsen, founder of UnoArch
The founder

Stig Sörnsen

Stig started in 2012 carrying the on-call pager for a hosting company, and moved on through automation, DevOps and development leadership to enterprise architecture. He brought four countries onto one shared system, and led the technical carve-out of Sentia Denmark after Accenture acquired it, with no downtime for customers.

Why UnoArch exists

In 2026 he founded UnoArch to build full time. Five platforms are in production today, and the studio designed, built and runs every one of them. The lesson from both worlds is the same: architecture that nobody can build is not architecture.

What that means for you

Both sides of the table

Most studios either understand large organisations or can ship a complete product fast. UnoArch was built to do both.

  1. 01We understand the business problem before we write a line of code.
  2. 02We can tell you what a system will really take, because we build and run them ourselves.
  3. 03We stay until it runs, and we tell you plainly when something will not work.
