Structure, liquidity, and control for the continuity of wealth
The authors bring to this work decades of direct advisory experience with entrepreneurial families across the United States and Latin America. The theoretical framework developed in the book is grounded in that practice — in the patterns, vulnerabilities, and structural solutions that only become visible through sustained engagement with wealth at this scale and complexity. The book represents, in this sense, a codification of what the practice has taught.
The book is not the source of the Sentinel methodology — it is its documentation. The approach to wealth architecture described in these pages was developed through years of direct engagement with entrepreneurial families navigating the full complexity of significant wealth: liquidity challenges, succession pressures, governance gaps, and the structural vulnerabilities that compound silently across decades of incremental decisions.
This is the central thesis of the book, and of the Sentinel practice. Wealth that is managed as a collection of instruments — however excellent individually — is vulnerable to the systemic risks that only become visible when the estate is understood as a whole. The book develops this thesis across four parts, drawing on the theoretical foundations of systems thinking applied to the specific context of entrepreneurial family wealth.
The first part examines the origins of significant entrepreneurial wealth — the cultural, leadership, and enterprise dynamics that create it, and the structural implications of its concentration in a business owner's hands. It addresses the paradox of the entrepreneur's wealth: simultaneously the most concentrated and the most generative configuration of capital, and therefore the one most in need of architectural discipline from an early stage.
The second part addresses succession as the central structural challenge of entrepreneurial wealth — not merely as a legal or tax exercise, but as the test of whether a wealth architecture is genuinely built for continuity. It examines the patterns of succession failure, the governance structures that prevent them, and the cultural dimensions of wealth transfer that no legal document can substitute.
The third part develops the architectural framework at the core of the Sentinel methodology — the integration of risk, liquidity, and continuity into a single decision-making system. It provides the analytical vocabulary and the structural models that enable families to understand and manage their wealth as a coherent system rather than a collection of independent instruments.
The fourth part presents the Sentinel methodology in application — illustrating how the four dimensions of wealth architecture (diagnosis, projection, liquidity, and continuity) operate in practice across a range of scenarios representative of the entrepreneurial families we serve. It concludes with the central argument for the architectural approach as the only framework adequate to the complexity of significant entrepreneurial wealth.
The book is not written for those seeking quick answers or immediate returns. It is written for entrepreneurs and families who understand that the most important decisions about wealth are not made in weeks but in decades — and that the quality of those decisions is determined not by the instruments chosen but by the framework within which choices are made. It is, in this sense, a book about patience, discipline, and institutional thinking applied to private wealth.
