## About

Principalis was established in 2017 as a multi-family office headquartered in Baech, Switzerland. It serves a small number of families through customized mandates that mirror single-family-office practices in asset allocation and manager selection. Leadership previously operated at Rianta Capital before founding the current vehicle. The firm directs capital into private equity, private credit, hedge funds, infrastructure, and real estate. Allocations span direct co-investments and SPVs as well as fund-of-funds commitments. Confirmed holdings include SFP AST Swiss Real Estate and RF-Promotion 2 in Switzerland together with the PMP Fund domiciled in Luxembourg. Geographic reach covers Europe, North America, Asia, the Middle East, Oceania, and South America. No public headcount or AUM figure is available. The firm maintains a strategic partnership with SFP Investment Foundation for real-asset transactions and oversees the Sigg family contemporary Chinese art collection. No operational events from the last 24 months appear in public records. Principalis functions as an exclusive vehicle limited to a select group of families rather than an open platform. This closed structure shapes its sourcing and governance around individualized mandates instead of standardized product offerings.
