Organisation focused on clients

The innovative business model of Maerki Baumann & Co. AG is concentrated on our core competencies of investment advisory and asset management. Our bank focuses on selected parts of the value chain and obtains highly standardised services from external partners. Our business model also reflects in our organisational and management structure.

Client focus

A consistent client focus is of central importance to us, and our organisation is structured accordingly. Flat hierarchies and swift decision‑making processes in the areas private banking, asset management and indirect real estate investments underscore this. The great value we attach to expertise for investment and financing solutions is manifest in the broadly based area of Investment Management. We supplement our in‑house know‑how through a comprehensive network of external specialists. PricewaterhouseCoopers AG acts as auditor.
