As record numbers of wealth owners move and invest internationally, wealthy families face a critical infrastructure question: Should we replicate our wealth management systems in new countries? Local expertise will always be essential, but the definition of "local" can be expected to evolve over time. Consolidated data infrastructure is key to avoiding unnecessary operational barriers as global footprints and portfolios expand.
The political climate for sustainable finance has cooled in the United States. Donald Trump’s return to the White House has weakened support for environmental, social and governance (ESG) policies. Fund flows show that enthusiasm has faded among some institutional investors. However, the picture looks significantly different from the viewpoint of family offices. These private vehicles, which manage wealth for ultra-wealthy families, continue to persist in sustainable investing.
The global family office market has reached $20.13 billion in value and is projected to hit $27.61 billion by 2030. This growth reflects a fundamental shift in how ultra-high-net-worth families approach wealth management, moving from simple stewardship to strategic value creation across generations.
For many family offices, the risks are no longer theoretical. Governance is informal, reporting delayed, and portfolios are growing more complex by the quarter. Yet many still rely on basic spreadsheets to track billions. According to Copia Wealth, citing KPMG data from 2025, more than 57% of global family offices continue to use general tools like Excel for core financial reporting.
Deciding whether to establish a family office is often one of the most important choices wealthy families make. A wide range of factors shape this decision. In this article, we examine three of them by comparing four wealthy families and their approaches to managing their fortunes.
María Asunción Aramburuzabala formed family office Tresalia Capital after her father Pablo – executive vice president of Grupo Modelo, the brewer of Corona beer that his own father Felix founded after the Mexican Revolution – died unexpectedly of cancer in 1995 at age 63 with no finalized succession plan. Today she is worth an estimated $8.2 billion, making her Mexico’s wealthiest woman and Latin America’s second after Chilean mining magnate Iris Fontbana. Her story holds three valuable lessons for today’s family office builders.
Today’s family offices face two challenges that seem to work against each other: keeping talented staff and controlling costs. Recent industry research shows this phenomenon to be widespread. Simply paying higher salaries is not the answer. The way forward is to invest in modern technology that transforms how family offices operate.
For centuries, ultra-wealthy families have been relying on dedicated teams to manage their financial affairs. These teams’ methods, operational scopes, and sophistication have evolved significantly in response to economic shifts, technological advances, and evolving global opportunities. By examining these transitions, we uncover valuable lessons for wealth owners building family offices in the modern era.
