Main Partner AG

Main Partner AG was established in Zurich in 2015 by Thomas Schär after an existing asset-management practice. The firm did not originate from a single industrial fortune; it instead aggregated mandates from multiple families seeking an external manager. It remains licensed by FINMA and supervised by AOOS. The firm concentrates on fixed-income strategies supplemented by private credit, real estate, hedge funds and secondaries. Mandates include portfolio construction in foreign banks, leveraged bond and derivative positions, and participation in IPOs and bond placements. Execution occurs through SPVs, fund commitments and direct co-investments. Geographic scope centers on Europe with additional exposure to international counterparties. Team size and total assets remain undisclosed. The firm lists one office at Münsterhof 5 in Zurich and maintains partnership agreements with leading Swiss banks. No philanthropic vehicles or club memberships beyond the Swiss Association of Asset Managers are recorded. No operational events from the last 24 months appear in public sources. Regulatory status under FINMA and the VSV-ASG creates a structural distinction: the firm functions as a licensed external asset manager rather than an unregulated single-family office, allowing it to serve multiple non-related families under Swiss supervisory oversight.
