Stefan Wiesli


As Managing Partner and Attorney at Law at Barandun in Zurich, I combine entrepreneurial thinking, international experience, and legal precision. I am driven by the interplay between legal and economic considerations – a dynamic that inspires me to develop solutions that are legally sound, strategically thought-through, and pragmatically implementable. Clients value my efficient, results-oriented advice and my exceptional dedication. As an active investor in real estate and InsurTech ventures, I bring economic insight directly into my legal work – particularly in M&A transactions, commercial and contract law, and the advisory of demanding UHNWI, asset managers, and family offices.
