ABOUT
Osiris Asset Management AG is a privately held company, founded in 2006 under the laws of Liechtenstein and governed by partnership principles. From the outset, our focus has been clear: delivering excellence in Fund Management and Family Office solutions of the highest standard.
​
Our operations are conducted in strict accordance with European laws and regulations and are authorized and supervised by the FMA – Finanzmarktaufsicht Liechtenstein. The firm is wholly owned by its partners, ensuring independence, alignment of interests, and a long-term perspective. As a collective of seasoned investment specialists, we dedicate our expertise to Fund Management and Global Wealth Management, serving private clients, families, and institutions with discretion and precision.
​
Our guiding principle is uncompromising excellence in investing. For us, this means striving to generate attractive returns without taking on disproportionate risks — an achievement possible only in markets that are less than “efficient.” While superior performance remains a central ambition, our foremost priority is the protection and consistency of capital. We measure success not only in periods of growth but, above all, in the ability of our clients’ portfolios to withstand volatility and preserve value through adverse market conditions. Our disciplined, value-oriented approach ensures resilience and sustained performance across full market cycles.
INDEPENDENT WEALTH MANAGEMENT
At Osiris Asset Management AG, we draw upon longstanding market experience and an unwavering commitment to excellence. Our mission is to deliver carefully conceived solutions, offering clients independent advice and support entirely free from external influence by asset managers, brokers, banks, or other institutions. This independence ensures that every decision we make is guided solely by the best interests of our clients.
​
Creating lasting value in today’s markets requires more than access — it demands a true knowledge advantage. For this reason, we have dedicated a specialized team to proprietary, in-depth research, following a rigorous and consistently applied methodology. Our research framework is built around identifying and articulating the fundamental elements that define a long-term investment case. This disciplined approach safeguards our clients’ capital, upholds their principles, and ensures that each investment stands on a foundation of clarity, resilience, and foresight.
EXPERIENCE AND DEDICATION
The team at Osiris Asset Management AG is wholly dedicated to generating lasting value for its clients. This commitment extends across investment strategies, legal advisory, tax-efficient structuring, estate planning, and rigorous risk management and monitoring. Equally important, it includes delivering pragmatic, common-sense guidance shaped by decades of hands-on experience.
​
Our approach is firmly rooted in understanding each client’s specific needs and delivering highly personalized services to address them with precision and care. Both the partners and the wider team bring a wealth of international expertise, being fluent in multiple languages and adept in diverse geographical markets. This global perspective, combined with local insight, ensures that our clients benefit from solutions that are not only tailored, but also resilient and forward-looking.
