Voluntary work

  • Voluntary judge of financial matters (Finanzrichter) for the election period 2021-2025 at the Finanzgericht Münster.
  • Voluntary member of the supervisory board (Aufsichtsrat) of DenktMit eG for the election period 2023-2024.

I actively support the work of/at CCC and Wikimedia DE. And I run a non-profit computer museum.

Let's go, start it up!

I put demands on my readers: You are required to detect irony. But, spoiler alert, each of the following startups has a valid core of truth. Can you find it?

  • Ohrenbaum GmbH is a small holding located in Münster, Germany. It was founded in April 2020. As a founding director, I'm doing the strategic direction.
  • Svantic institute is a novel research institute located in Münster, Germany. It was founded in April 2021 and is currently operating privately.


I'm on the web since 2000 and I had many generations of websites, some (most) of them being down nowadays. Sven.Köppel.org was my website in the 2010s. Ufopixel.de is another old project I was involved in. There are still plenty of ressources which can be found at my old website at Goethe University.

There are a couple of other Sven Köppel around, which are not me. These are for instance @testpilot76, this instagrammer or that person in Hamburg.
