## About

BS&MC originated in 1959 from the business law department of an established Swiss legal practice, forming a multi-family office in Lugano that now fields over 90 professionals. The firm operates across Europe, Asia, Africa, the Middle East, and South America. Its wealth-origin base is not publicly attributed to a single family; instead the group serves multiple families and entrepreneurs with trust, legal, and tax-advisory foundations. The firm deploys capital through a mix of direct co-investments, SPVs, private credit, real estate, infrastructure, and secondaries. Asset classes extend into collectibles, passion assets, and digital assets, with a crypto and blockchain advisory stream. Stage coverage spans venture capital, growth equity, and buyouts, with confirmed technology focuses in AI/ML and Web3. Geographic deployment reaches across 13 additional offices, including Luxembourg, Milan, London, Nicosia, and Dubai. BS&MC reported over 90 people firmwide, with the Rosa Riganti Foundation acting as its centralized philanthropic vehicle. Chairwoman Valentina Toto drives the foundation's art sponsorship and partner relationships, including ties with Trinity College Cambridge, Safinim SA, and Renexia. Nataliya Ottaviani serves on the SECA Ticino working group, anchoring the firm's Swiss private equity network. The group also operates Worldwide Properties Management SA in Lugano for commercial real estate holdings. The structural differentiator is the firm's embedded legal-and-tax boutique model — an architecture that makes cross-border structuring the central operating system, rather than a back-office afterthought. BS&MC's multi-jurisdictional licensing and its roster of corporate administration services create a compliance-forward posture that differs from pure investment-led family offices.
