Our Story
What began in 2013 as a small online stamp business gradually grew into an expanding enterprise. With more and more offerings and a steadily growing customer base, in January 2026 we took the next step and founded VENTIS Auktionen GmbH.
This development allows us to expand our services professionally and offer our customers an even better service. Our focus is on quality, fairness and personal care — values that have accompanied us from the beginning.

Our Philosophy
Trust through transparency
We value honest valuations and clear communication. Every customer should understand how we arrive at our assessments.
Quality in diversity
We offer not only selected individual items, but also well-curated collections and small lots. Every offering is carefully examined and fairly valued.
Personal care
Every collector is unique. We take time for your concerns and advise you individually — whether beginner or experienced philatelist.
Long-term relationships
We accompany many of our customers over many years. This loyalty is both an honour and a commitment for us.
