Rich people tend to “make their money work for them” by setting aside capital to invest through specialized investment offices or investment vehicles. These vehicles offer superior expertise, client trust, flexibility, and personal service, usually all at the same time. There are three important types of vehicles: Family Offices (FOs) or Multi-Family Offices (MFOs), Investment Networks or Clubs (e.g. 990 Capital), and Large Wealth Management Companies (e.g. Blackrock). All of these tend to be highly exclusive, and information about them tends to be limited. Family Offices are the most exclusive, dedicated solely to serving a single client and his/her family. Multi-Family Offices do this but for several ultra-rich families, which is possible because of the cost cutting they can do by spreading their operations over multiple clients.
