Philipp Kieber on legacy, leadership and continuity at Interadvice Anstalt

Interadvice Anstalt has been guiding families through wealth, structure and succession from Liechtenstein for more than a century. Today, Philipp Kieber carries that legacy as the fourth generation to lead the firm. In this Q&A with The European, he reflects on how a close, steady organisation responds to tighter regulation, diverse client needs and global movement — and why long-term trust remains its most valuable asset

Interadvice Anstalt has spent more than 100 years helping families organise wealth, succession and long-term governance from its base in Vaduz. The firm’s history is unusually continuous: three generations have taken responsibility for it, with each handover designed to keep the organisation stable rather than reshape it. Philipp Kieber now occupies that position in the fourth generation, serving as both director and executive board member, and guiding the business through an environment that is more international, more regulated and more closely scrutinised than the one his great-grandfather entered in 1922.

Beyond his role at Interadvice, Kieber founded LieAdvice AG to provide accounting and tax support for local clients who need practical handling as well as long-term structuring. The two responsibilities sit side by side, with one focused on cross-border governance and succession and the other on the day-to-day mechanics that make those structures durable. It gives him sight of both ends of the work — from design to execution — and has shaped how he thinks about shifting expectations, regulatory pace and the value of steady client relationships over time.

Known for a calm, non-authoritarian and people-centred leadership style, Kieber describes his approach as “not just about numbers but about people, decisions, and the right sense of proportion”.

In this conversation with The European, he discusses how fiduciary work is changing, how generational continuity shapes decision-making, and how regulatory and client demands have broadened the scope of the role. He also reflects on the balance between discretion and transparency, and on the practical considerations of running a firm with deep roots in Liechtenstein and clients spread across multiple jurisdictions.

The European: How do you tailor fiduciary services to meet the needs of international clients?

Philipp Kieber: For us, it always starts with listening. International clients come directly or via an adviser with different legal frameworks, family setups and expectations, and we take the time to understand that. From there, we build structures that feel natural to them, not imposed. Liechtenstein gives us a flexible toolkit, and with our network abroad we can bridge jurisdictions smoothly. The goal is simple: a solution that works quietly and reliably in the background.

What distinguishes Interadvice’s approach to family office services?

We come from a long tradition of looking after families. That shapes how we work. Clients appreciate that we stay close, remain available and keep the circle small. When we manage foundations or trusts, we do it with a forward-looking perspective. It is about continuity and ongoing support rather than complexity for its own sake.

How do you define “valued encounters” in your client relationships?

A valued encounter is one where both sides leave with clarity and trust. We prefer conversations that are thoughtful, unhurried and personal. Many clients have been with us for decades, some across generations. That only happens when interactions are respectful and proportionate. It is part of our culture, and we guard it carefully.

What trends are shaping the future of fiduciary services in Liechtenstein?

Regulation continues to increase, not only in Liechtenstein but worldwide. Currently, geopolitical circumstances are making compliance even more challenging. At the same time, Liechtenstein has positioned itself for many years with a long-term, sustainable perspective and thus a broad implementation of new regulations. This will continue to shape the industry: responsibility, professionalism, and a greater need for well-considered decisions.

How does LieAdvice AG integrate accountancy and tax services with your core offerings?

LieAdvice allows us to support clients in a practical way. While Interadvice focuses on international structures, LieAdvice handles accounting, local taxes and day-to-day administration for international and local clients. The two sides complement each other. For our clients, it means they can rely on one coordinated approach rather than juggling multiple advisers.

What challenges do you face in balancing discretion with global compliance standards?

Discretion has always been part of our work. But today it must be paired with complete clarity towards regulators. That balance is delicate, yet essential. We manage it by applying strict acceptance criteria, documenting purpose and intent thoroughly and staying close to developments in sanctions and reporting regimes. It is not about secrecy, it is about professionalism.

How do you stay ahead of regulatory shifts across jurisdictions?

We learn continuously. Regulation changes quickly, and you cannot afford to be reactive. We follow developments closely, speak with specialists in other countries and adjust our structures early when needed. For us, staying ahead is not an ambition, it is part of safeguarding the stability our clients expect.

What innovations are you exploring to future-proof your services?

Our innovation is measured, not loud. We focus on governance, sustainability and substance, because those elements will endure. With a century of history behind us, we think in long arcs. If structures are well documented, well governed and aligned with the direction Liechtenstein is taking, they remain robust. That is the kind of future-proofing we believe in.
