FOSS’s mission is to make the family office concept as clear and understandable as possible. In 2011, founders Jan van Bueren and Thomas Ming became aware that most families trying to establish a single-family office or appoint a multi-family office experience this as really challenging.

  • Developing a sophisticated and highly structured process to support families with the establishment of their customised single-family office; and
  • Establishing an unconventional multi-family office database containing essential information for families worldwide to enable them to properly select the best multi-family office.

Global reach

After years of thorough research and passionate commitment, Jan van Bueren and Thomas Ming have been able to establish themselves as a recognised and independent source of advice for international affluent families. They are regular speakers at family office conferences, family business meetings and educational events, and the authors of numerous articles about setting up a single-family office or selecting a multi-family office.

FOSS originally launched its services as «FOSS Family Office Services Switzerland». Several years later it changed its name to «FOSS Family Office Advisory» to better reflect its global reach. Since its foundation, FOSS’s achievements in service delivery have been recognised with several awards.

FOSS forms an integral part of the Wealth Planning Services of Union Bancaire Privée, UBP SA (UBP) in Switzerland. UBP was founded in 1969 by Edgar de Picciotto; since then, it has remained a privately-owned independent Swiss financial institution. The Bank’s activity is exclusively focused on wealth management for private and institutional clients, with clear targets of preserving and generating wealth over the long-term.

As UBP does not offer in-house family office services to its clients, its FOSS team is in an excellent position to advise you in a professional and objective manner on the selection of a multi-family office or the establishment of a single-family office.

UBP is one of Switzerland's best-capitalised private banks, guaranteeing long-term financial stability and strength (learn more about UBP's key figures).


Headquartered in Geneva, the Bank is also present in Switzerland's other financial centres – Zurich, Basel, and Lugano – as well as in some 20 locations worldwide, ...

    ... enabling it to combine local know-how with a strong international network. Its private banking booking centres include Hong Kong, London, Luxembourg, Monaco, Nassau and Singapore.

    In the space of one generation, the Bank has established itself as one of Switzerland's leading private banks. Therefore UBP is often used by independent asset managers as their custodian bank of choice. UBP is specifically recognised for its expertise in traditional and alternative asset management. Its integrated approach enables high-net-worth clients to benefit from a quasi-institutional management of their wealth and to benefit from the Bank's highly knowledgeable and skilled experts.

    Moreover, the Bank offers wealth planning advisory services committed to supporting clients in their search for reliable solutions in order to secure, grow, and transfer their family estate over generations. UBP’s wealth planning advisors closely cooperate with various prestigious external specialists, including highly qualified Swiss and international lawyers, tax advisors, chartered accountants, and seasoned administrative services providers, building an extensive network of renowned partners over the last 30 years.
