(Our Story)
(About)
AVIONMAR is a boutique business aviation broker based in Vienna. Founded by Stefan Duller in 2010, the firm grew out of a banking career — and that discipline still shapes how we work: rigorous analysis, careful structuring and absolute discretion on every mandate.
We acquire, sell and finance business jets for a worldwide clientele, drawing on an extensive network of operators, OEMs and brokers. As a member of the EBAA, we operate to the standards of the European business aviation community — and as a boutique, we give every transaction the senior attention it deserves.
Every mandate is led personally and handled with complete discretion. There are no junior handoffs and no conflicting house positions to work around — just senior attention on the details that move a transaction forward.
From the first valuation to final delivery, we sit on one side of the table — yours. That clarity is what brings clients back to us, transaction after transaction.

(From the Founder)
A jet transaction is built on trust. We represent one side of the table — our client’s — and protect it with the same care we would our own.
