K-Advisory GmbH

K-Advisory was founded in 2008 by Peter Kölliker, after 30 years as an auditor at EY — most of it spent with river cruise operator Scylla Tours, where he built deep expertise in Swiss direct taxation and European VAT.

Three years ago, Peter handed leadership of the firm to his son Daniel. Today, both work together — combining three decades of institutional knowledge with a new generation's perspective on European VAT, Swiss tax and corporate advisory.

That continuity is the point. Clients don't work with a rotating team of consultants; they work with the same two people, over years, who already understand their business.
