Scaling Impact by Kusi Hornberger is included as a core reference for the chapter 'Exploring the Landscape' because it maps practical strategies, structures, and practices—such as blended finance, impact-first investing, patient capital, catalytic DFI roles, results-based philanthropy, and combined finance-plus-support—to reimagine how capitalism can be more inclusive and accountable; the website’s summary and paradigm-shift sections directly align with the row’s 'Why read' rationale and show how the book connects systemic theory to actionable changes for scaling impact.
