We build, upgrade and run Umbraco websites for universities, insurance brokers, media and B2B companies. More than 10 years on the platform, sites with up to 80,000 pages, and our own packages that other Umbraco teams install from NuGet.
Pick one piece or hand us the whole lifecycle. Each card links a client project where we shipped that kind of work.
Corporate sites, portals and content platforms built on current Umbraco and .NET, designed so editors can work without developers.
We move older Umbraco sites to the current version, including the jump from .NET Framework to modern .NET, without losing content or SEO.
One Umbraco installation that runs several brand sites, or Umbraco as a headless CMS feeding React, Next.js or mobile front ends.
Custom editors, dashboards, workflows and packages that make the Umbraco back office fit how your team actually publishes.
Umbraco connected to the rest of your stack: identity, CRM, marketing automation and external data sources.
Fast search, sensible caching and automated deployments on Azure or AWS, followed by ongoing maintenance and security updates.
From Umbraco 7, 8, 10 or 13 to Umbraco 17 LTS, with content migration and redirects.
Security updates, fixes, small features and help for editors on live sites.
Senior Umbraco and .NET developers for your team or under your agency brand.
Older Umbraco versions no longer get security fixes and run on the retired .NET Framework. Packages stop working, hosting gets harder and fewer developers want to touch the code. An upgrade fixes that, and it is a good moment to clean up the content model.
For Jongeneel, a transport company, we moved an operations platform from Umbraco 8 and .NET Framework to Umbraco 17 on .NET 10, and added automated tests, Docker and CI/CD along the way. Read the case

Yes. OSKI Solutions is a Registered Umbraco Partner. We have built on Umbraco for more than 10 years and maintain 11 Umbraco packages on NuGet, most of them free and MIT-licensed, with more than 50,000 downloads in total.
Umbraco 7 and 8 no longer receive security fixes and run on the old .NET Framework, so hosting, packages and developers become harder to find each year. We usually recommend moving to the current long-term support release. We start with an audit and give you a fixed estimate before any work begins.
Yes, this is a large part of our work. We review the code and infrastructure first, fix urgent issues, document what we find and then agree on a maintenance or improvement plan.
A focused upgrade or a mid-size corporate site typically takes 6–12 weeks. Large platforms with migrations and integrations, such as university or multi-brand sites, run over several months in phases. You get a timeline with the estimate after discovery.
Anywhere that runs .NET: Microsoft Azure, AWS, Umbraco Cloud or your own servers. We have run Umbraco on Azure, on AWS ECS with Docker, and moved large sites between the two without downtime.
