## About

United Multi Family Office opened in 2017 as a single-family office before Gustavo Henrique Fernandes and Victor Urbano Buonfiglio Valezim converted it to a multi-family model the following year. Both founders previously worked at Credit Suisse Hedging-Griffo and Banco Safra. The firm offers investment consulting, patrimonial consolidation, succession and tax planning, holding structures, heir preparation, and concierge services. All work occurs inside Brazil with a focus on South America. Compensation combines an assets-under-advisement percentage for securities with direct payment to third-party specialists for non-investment mandates. Additional partners joined between 2023 and 2025, including Monique Kahtalian and Mauricio Abdalla. The firm maintains one office in São Paulo’s Vila Olímpia district. No public portfolio holdings, AUM figures, or co-investment activity appear in available materials.
