Individually strong, powerful together.


Trust, the foundation
of a partnership.

The number eight, known as "Octa" in ancient Greek, has long symbolized auspicious beginnings, renewal, empathy, assertiveness, and effectiveness. Our name accurately reflects our identity and mindset:

The "auspicious beginning" represents the founding partners coming together 23 years ago in the Private Banking division of the esteemed traditional Bank Leu. "Renewal" signifies the establishment of Octa Wealth following years of successful collaboration at the Asset Manager Sound Capital. "Empathy," "assertiveness," and "effectiveness" are the defining attributes for us.

As a well-coordinated and proven team, we continue to shape our story. In the upcoming chapters, we see trustful, partnership-based relationships with our clients as the key to sustainable success.

Founded 23 years before its inception.

Octa Wealth traces its origins back to the year 2000 when its founding partners, led by Christian Sieber, collaborated within the Private Banking division of Bank Leu (later renamed Clariden Leu). In 2012, Christian Sieber and his senior partners embarked on a venture to co-found Metropol Partners, later rebranded as Sound Capital, all the while ensuring a seamless transition in client service.

After 11 successful years, the decision was made to depart from the existing setup and establish a new, dynamic, and independent wealth management firm under the name Octa Wealth. The primary objective was to remain true to the existing philosophy and continue providing the highest level of service to their clientele.

The core principles of this endeavor are partnership-based relationships built on trust, acting in the best interests of the clients, and leveraging experience, passion, independence, and a dynamic structure that allows for customized solutions tailored to individual needs.


Solutions as unique as the challenges.

We prioritize our clients' wishes and goals, managing their wealth accordingly and addressing their concerns.

Wealth Management

We prioritize our clients' return expectations and risk preferences. Our goal is to implement their chosen directives using the best available investment products. Together, we analyze the situation and select a suitable investment strategy, which we execute through our portfolio management.

Portfolio Management

We meticulously tailor individual and sustainable solutions to our clientele. Our independence enables us to choose investment products and ensure a transparent fee structure. Collaboratively with our clients, we establish investment objectives and strategies.

Investment Policy and Strategy

Our foremost focus is safeguarding and managing wealth within agreed parameters. We firmly believe in the long-term investment strategy, consistently delivering optimal results. Our strategies are crafted with foresight to endure crises, turbulence, and disruptions. We meticulously analyze short-term market fluctuations and capitalize on opportunities. All investment decisions are collaborative within our Portfolio Management team, and our lean, dynamic organization allows us to adapt flexibly to current market conditions.

Family-Office Services

Our Family Office services relieve our clients of wealth-related burdens, enabling them to fully enjoy life. We manage all aspects of their assets, including investments and financing, provide consolidated reports, and assess the suitability of other service providers (such as tax advisors and retirement planners) to meet individual needs. Our primary focus is on performance and cost control, including effective cash management. We help our clients ensure that their wealth effortlessly supports their desired lifestyle.
