Fiduciary work as stewardship.

Tiamat Treuhand works with entrepreneurs, families and companies who value discretion, precision and a long-term perspective. We do not seek volume. We seek alignment — mandates where we can add genuine value, where the relationship can deepen over the years, and where our work contributes meaningfully to the financial clarity of those we serve.

Our work spans the full range of fiduciary and advisory services: accounting and reporting, tax advisory, company formation, payroll, trusts and succession, compliance, CFO advisory, real estate portfolio management, and restructuring mandates. But the common thread is not the service — it is the standard. Every engagement, regardless of scope, is treated with the same care, the same rigour, and the same long-term orientation.

Switzerland sets a high bar. We hold ourselves to a higher one. The regulatory environment here is demanding, the standards are exacting, and our clients deserve advisors who not only meet those standards but operate well ahead of them. That is the Tiamat commitment.
