R & S Associates
R & S Associates was established in Geneva in 2009 by Irina Rentsch, building on her tenure as a senior private banker at Pictet & Cie. The firm operates as a multi-family office serving international clients who require tax optimization, trust administration, and coordinated family governance alongside active portfolio management. The firm's deployment spans private equity, private credit, hedge funds, infrastructure, natural resources, and real estate — both direct and fund commitments — across Europe, North America, Asia, and Oceania. The partnership's co-location with Necker Finance (Suisse) SA, where business partners Rémy José Louis Mabillon and Fabien Kurer hold board roles, adds structuring capacity for cross-border assets. Technology interests cluster around AI/ML, workflow automation, and supply-chain tools. The advisory board includes real-estate specialist Tatiana Vogt and legal counsel Tatyana Proskurnya, while partner Jimmy Chu focuses specifically on Europe–China investment corridors. R & S Associates maintains a physical-asset portfolio that includes the Bergwelt Grindelwald alpine resort, a luxury chalet portfolio in the Swiss Alps, private-school investments in Switzerland, and healthcare assistance services in Geneva. The firm participates actively in the Swiss-Chinese Chamber of Commerce and its Romande section, reinforcing bilateral deal-sourcing channels. An art advisory portfolio operates alongside the main investment activities, and the firm is linked historically to philanthropic support for the National Gallery of Art in Washington, D.C. The firm's structural distinction lies in combining Swiss fiduciary infrastructure with an explicit mainland China investment corridor — a pairing few European multi-family offices match. Co-location with a regulated Swiss financial intermediary, an advisory board stacked with legal and real-estate operating expertise, and ownership of operating hospitality assets give R & S Associates a posture closer to a merchant-family office than a pure allocator.
