Abstract

Healthcare angel investing presents a unique temporal challenge that fundamentally differs from other venture categories. While software and consumer technology companies may achieve liquidity events within five to seven years, healthcare companies routinely require ten to fifteen years or longer to reach meaningful exits. This extended timeline creates a distinctive long-tail return distribution that challenges conventional venture portfolio theory and investor psychology. This essay examines the structural factors driving extended holding periods in healthcare ventures, analyzes the implications for portfolio construction and fund economics, and explores how sophisticated angels can optimize for these temporal dynamics. Key findings suggest that successful healthcare angel investors must reconcile the mathematical advantages of power law returns with the psychological and practical challenges of decade-plus holding periods, requiring distinct approaches to portfolio size, diversification, reserve allocation, and investor expectations. The analysis draws on empirical exit data, fund performance metrics, and detailed case studies to illuminate the specific timing challenges facing healthcare angels and propose frameworks for navigating this unique investment landscape.
