Modern business IT. Planned in person, built properly.
I plan, modernise and support business IT for small and mid-sized companies, from Microsoft 365 and IT security to network, servers, telephony and automation. In Hamburg and remote.
Where people usually start.
„Our IT has grown over the years and nobody has the full picture any more.“
Bring structure to existing IT→„We use Microsoft 365, but nobody ever planned permissions, devices and file storage as a whole.“
Set up Microsoft 365 properly→„We want to know whether we are prepared for a cyber attack, and what we are still missing.“
Put IT security to the test→„Our Wi-Fi and network work somehow, but not reliably.“
Modernise the network→„We are changing IT provider or moving offices and want no gap in operations.“
Changing provider and moving→„We have our own IT team but need extra expertise on specific topics.“
Support your internal IT→„„Our mobile and landline contracts have grown over the years. Nobody has a full view of the terms, the costs and the tariffs any more.““
Manage and optimise contracts→„„A lot still runs manually. We want to automate, and to use AI where it genuinely takes work off our hands.““
Automation and AI with a target picture→Your situation is not listed?
Describe it in two sentences. You will get an honest assessment.
Seven areas. One person to talk to.
Cloud, network, servers, security, devices and processes are connected. So I do not just look at the single problem but at the environment behind it, from planning through to day-to-day operation.

Understand, plan, build, support.
-
01
Understand
Look at the existing environment and the requirements before changing anything.
-
02
Plan
Agree priorities, effort and sequence. Not every piece of infrastructure needs replacing.
-
03
Build
Carrying out the planned changes myself, ideally without interrupting day-to-day operation, and documented so it can be followed.
-
04
Support
Ongoing support and further development, if you want it.
From real projects.
IT for a medical practice: email with built-in protection, new practice software and a stable network
A specialist medical practice renews email, practice software and network without the practice standing still.
Microsoft 365 for a non-profit: SharePoint, mailboxes and telephony in Teams
A distributed team brings collaboration and telephony together in Microsoft 365. No office phone system, supported entirely remotely.
Reinforcing in-house IT: an Apple fleet under management, mailboxes to the cloud
An agency working exclusively on Apple devices gets its device management, mailboxes and file storage in order. As a complement to the in-house IT, not a replacement.
From practice, for practice.
What clients say.
Thank you for the excellent collaboration, we look forward to more projects together.
Thanks to the new internal wiki Mr Korbjuhn built for us, colleagues now usually find the answer to questions about standard processes themselves, which noticeably takes the load off the IT department.
It is hard to believe how much time you save once rudimentary Excel skills are developed a bit further. There is plenty to learn, of course, but it is fun and it really pays off.
The training was great! You simply learn far more effectively when it is explained to you personally and that clearly. I am happy to recommend Mr Korbjuhn.
I do not just advise. I build it.
I am Franz Korbjuhn, a self-employed IT consultant and IT service provider based in Hamburg. I work with small and mid-sized companies and with in-house IT teams — from the technical decision through delivery to day-to-day operation.
I do not only advise, I implement the solutions I propose myself. That is why you get a realistic recommendation and not automatically the product with the highest margin.
- Understand first, change second.
- No more complicated than it needs to be.
- Technology is a means, not an end.
- Knowledge stays with you.
