About Stelvion Systems

We are your IT department.

Founded by Fabian Lessmann to give small businesses enterprise-grade IT without the enterprise complexity. One partner, one platform, complete peace of mind.

My Story

Why I started Stelvion

I spent years working as a developer and IT professional in the German defense sector. That taught me what reliable infrastructure actually looks like and what it takes to keep systems secure. But it also showed me a problem: professional IT is too expensive for most small and medium-sized businesses. And the traditional service providers? Outdated processes, slow response times, and surprise invoices.

Something else stuck with me: it matters where your data lives. If your infrastructure depends on non-European providers, that is a risk, not just for you, but for your customers and theirs. So I set out to build a platform where you can run the services you need, hosted in a secure European environment you actually control.

The idea behind Stelvion is straightforward: a clean interface that does not overwhelm you, a setup that works from day one, and one contact person who knows your business. No ticket queues, no rotating support staff, just someone who takes care of your IT so you do not have to.
