We are your IT department

Founded by Fabian Lessmann for start-ups, SMEs and companies with high demands on security, data protection and technological sovereignty.

My Story

Why I started Stelvion

Hey, Fabian here! I have been building software and running IT systems for more than ten years, eight of them as an administrator and developer in the German security sector.

Keeping track of these fields has always been hard. The market moves fast and new technologies appear every few weeks. AI and vibe coding have shifted that pace to almost daily. Many companies struggle to keep up. At the same time, data protection has played a decisive role for years now, and it is often unclear where you are even allowed to store your data and which providers are safe.

On top of that comes political uncertainty, and you start asking whether depending on non-European software is still justifiable at all. Many public institutions are already switching to open-source solutions to become independent and regain full control over their data.

This is exactly where Stelvion comes in. Stelvion offers a platform for start-ups, SMEs and companies with high demands on security, data protection and technological sovereignty. With fully managed servers that meet European and German security standards, we run the business software of our customers and support them as a consulting partner.

I would be glad to support you and your company on this journey with Stelvion.
