We connect humans and software with AI
Deep technical expertise meets AI innovation. We help organisations modernise, build, and scale software that drives real business value using AI agents.

Three areas, one approach
End-to-end AI solutions from strategy to production.
Agentic Development
We build custom AI-native solutions powered by agents — delivered through an agile process we continuously improve and automate. Robust architecture, high performance, and security from day one.
Learn moreAI Adoption
We help your teams succeed with AI — not just experiment with it. From identifying the right workflows to deploying agents in production, we focus on outcomes that stick.
Learn moreAI Sovereignty
When data is sensitive or business-critical processes demand full control, we help you win with local AI. Deep experience with open-weight models and open-source tooling keeps you in charge — no cloud dependency, no black boxes.

Insights and conversations
All articles →Migrating a Full Website to Optimizely CMS 13 with Visual Builder in Four Hours
Four prompts, fourteen agents and one evening: how AI agents rebuilt umage.ai on Optimizely CMS 13 with Visual Builder, starting from an empty folder. What it cost, what it reached for, the CMS 13.5.1 gotchas it hit, and the caveats that keep the four hours honest.
After It Ships: Introducing AnnotateTheWeb
The most useful feedback on a website arrives after it ships, from clients, editors and testers who will never run your dev server. AnnotateTheWeb, our new hosted tool, lets them point at what's wrong on any live site and sends the note to your team, or straight to your AI agent over MCP.
Point, Don't Prompt: Introducing Redline
Giving an AI agent feedback on a UI usually means screenshots, scribbles and a long chat message. Redline, our open-source overlay, lets you point at the running app instead, collect a batch of notes without breaking your flow, and hand the agent everything it needs to find the code.
umage
[ˈuˌmæːjə]
Danish for giving a damn.
Most people do the work. We do the umage. There is no English word for it — the closest you get is "taking pains," but umage has none of that suffering. It is the quiet commitment to doing something properly, because the result matters.
Questions we hear often
What is AI Sovereignty?
AI Sovereignty means running AI on infrastructure you control — using open-weight models and open-source tooling rather than third-party cloud APIs. It lets enterprises put AI to work on sensitive data and business-critical workflows without sending that data outside their environment. umage.ai specialises in designing, deploying, and operating locally-hosted AI.
What is Agentic Development?
Agentic Development is software delivery where AI coding agents do a meaningful share of the work — writing, reviewing, refactoring, and testing code under engineer direction. It compresses idea-to-production cycles dramatically. We run up to 12 concurrent coding agents on a single engineer's machine and have taken production-ready open-source apps from idea to release in 26 hours.
Do you work with open-weight or locally-hosted large language models?
Yes. Running LLMs locally is a core part of what we do. We have run and tested 40+ open-weight models and routinely help clients evaluate which model fits a given workload, how to deploy it on-premise or in a sovereign cloud, and how to integrate it with existing systems through RAG and agent architectures.
Where is umage.ai based, and who do you work with?
umage.ai is based in Virum, Denmark (Teknikerbyen 5, 2830 Virum). We primarily serve Danish and other Nordic enterprises, working on-site and remotely. Reach us at hello@umage.ai or +45 7071 3333.
Who leads umage.ai?
umage.ai was founded by three partners: Allan Thræn (Optimizely MVP with 25+ years in software architecture), Martin Ottosen (former Director of Product Management at Optimizely and Product Architect at Sitecore), and Morten Aslo-Østergaard (.NET architect with deep AI-sovereignty experience and a DTU engineering degree).
