We build complex platforms, and get them to production.
New platforms, systems that finally talk to each other, and a senior second opinion before the expensive decisions. We have built and run five platforms of our own. Yours can be next.
Five platforms. All in production.
We do not only build for others. We build, own and run our own products, from coaching software to picture books to sales proposals. It is the clearest proof of what we can build for you.
Four ways we help
The same studio that built the platforms above can build yours, connect your systems, or sit at the table as your technical partner.
Platform development
You have a business problem that needs software. We take it from the first idea to a platform real people use every day, and we build it to keep running.
- Shaping the product and the first version
- Architecture that holds as you grow
- Payments, data, AI and integrations done properly
- Launch, then hand over or run it for you
Integrations & automation
Most companies do not need one more system. They need the ones they already have to work together. We connect them, and turn the manual weekly routines into software that runs by itself.
- Webshop, ERP, finance and CRM connected
- Manual routines turned into automated flows
- Logged, documented and monitored
- Built on the tools you already use
Technical partner
For founders and ventures that need someone to own the technical side. We make the build-or-buy calls, lead the build hands-on, and stay until it runs for real users.
- Own the technical side of the venture
- Make the build-or-buy calls
- Lead the build, hands-on
- Stay until it runs for real users
Advisory
Architecture choices, mergers and systems that have grown out of control. You get advice from someone who has built and run these systems, not only drawn them, in plain language.
- Architecture and platform reviews
- Carve-outs, mergers and separations
- Stabilising systems nobody dares to touch
- Build, buy or fix: a straight answer
Enterprise judgment. Startup speed.
Behind UnoArch are fifteen years inside enterprise IT, where systems are not allowed to fail: carve-outs, mergers, and platforms shared across countries. That experience goes into every system we build, at the speed of a small, senior team.
- 01Led the technical separation of Sentia Denmark after its acquisition by Accenture, with no downtime for customers.
- 02Brought four countries onto one shared way of working and one set of systems.
- 03Merged a group of acquired companies into one operation, and retired the old systems behind them.
- 04Cut a manual business process by 90% by automating the core of it.
One senior architect, from the first call to production.
UnoArch was founded by Stig Sörnsen, an enterprise architect who spent fifteen years making large systems work, and who now builds complete platforms hands-on.
You talk directly to the person who designs and builds your system. No account managers, no handoffs, no doubt about who is actually doing the work.
Built to run, not to demo
Everything we build is measured the same way: does it work in production, for real people, on a normal Tuesday.
Production is the finish line
A plan that only works on paper is not done. We stay until the system runs for real users, and we build it so it keeps running.
Senior judgment, small-team speed
We build with AI-assisted development, which lets one experienced architect move like a team. The decisions, the architecture and the responsibility stay senior.
The hard parts come first
Payments, privacy, security and numbers that must be exact are designed in from day one, not bolted on before launch.
Plain language
No jargon and no inflated reports. You get a straight answer about what is true, what it costs and what to do next.
