About us.

Arcus is the latin word for Arch. The Roman Arch was the foundation of Rome’s architectural mastery and thus, is the symbol of strength and stability. Arcus Finance SA finds its roots in 1991 when Louis Olivier teamed up with two other entrepreneurs to create the very first independent wealth management company in Geneva, Gesfinance SA. The pioneering and growth-oriented spirit of Louis Olivier enabled him to expand the business, this is how Arcus Finance SA was founded in 1998. By surrounding himself with a trustworthy and qualified team, he met the challenge of responding to his clients’ needs under a business model which was rare at that time.

Today, Arcus Finance SA has grown into a team of 20 people including administrative and trading support as well as wealth managers. The core team has been strengthened by the addition of team members which enables the company to combine experiences, dynamism, tradition and modernity. It stands out from its peers by perpetuating an entrepreneurial legacy and integrating a young vision of wealth management. It, indeed, believes that successful continuation is key.

Arcus Finance SA gathers not only the same values from experienced professionals but also diverse skills. The team consists of a wide range of individuals with solid financial knowledge gained through reputable banks. Their combined expertise allows Arcus Finance SA to adapt itself to a fast-moving financial environment and to be specialized in both developed and emerging markets.

Arcus Finance SA is registered under Swiss law and is a member of the Swiss Association of Asset Managers (SAAM).
