About FONS Family Office Network Service SA
With a strong emphasis on finance and ethices, our clients' interests are at the heart of our work. Founded in 2003 in Geneva, the Family Office Network Service SA is a family office born of a desire to create a link between Switzerland and Japan by offering advisory and auditing services in the context of wealth and asset management to Japanese clients. Although the company has since moved away from the Japanese market, it still retains its original essence, notably because of the long-standing collaboration between its founders and these clients. It continues to operate in Switzerland and Japan, but also internationally.
Combining a passion for the protection of family assets, a strong interest in finance and a taste for art, we offer a wide range of services applicable to these areas. Whatever your problem, we can help you!
