I am a business angel and entrepreneur

I am founder of Visual Meta GmbH and acted as shareholder and managing director until 2018, when I sold my remaining shares to Axel Springer / idealo. Together with "Saarbrücker 21" (SB21) - a group of friends and successful entrepreneurs - I invest in innovative startups.


We are focused on supporting the founders and companies we invest in. We only invest our own money and take a long term approach, without any pressure for exits. We also like sustainable dividend models. All of us run or have run successful companies and thus can provide useful insights, make introductions and support with follow-on financing rounds.
