Giving you unique insight into a hidden industry

FOSS's mission is to make the family office market as transparent as possible for you. In 2011, Jan van Bueren and Thomas Ming found that almost every family trying to hire a multi-family office found the market as exceedingly non-transparent.

Since then, they have committed themselves to providing a solution to this problem, with the ultimate goal of making it possible for every family to get easy access to custom-made family office services and high-quality wealth management.

To achieve their goal they have been focusing on three main objectives:

  • creating an extensive internet-based educational platform about the concept of family offices and the wide range of services they provide;
  • establishing an unconventional multi-family office database containing essential information for global families to enable them to properly select the best multi-family office and;
  • developing a bespoke evaluation process to determine the unique needs and wishes of each individual family.


After years of thorough research and passionate commitment, they have been able to establish themselves as a recognised and independent source of information for affluent families. As a result, these families are now being offered a light to guide them through the complicated and non-transparent world of the multi-family office service's industry. As of 2016 FOSSs services are extended with single-family office advisory.

Jan van Bueren and Thomas Ming are regular speakers at family office conferences, family business meetings and educational events, and the authors of numerous articles about setting up and selecting (multi-)family offices. Since its inception FOSSs unique service has been recognised with several awards.

Tier 1 Capital Ratio:27.5%
Assets under Management (in CHF):125.3 bn

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.

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.
