Investment thesis
4D Capital invests in digital healthcare companies at an inflection point driven by major industry transformation. The healthcare sector—representing 17-20% of U.S. GDP and reaching $5 trillion in 2024—is being reshaped by telemedicine, remote monitoring, AI-driven decision-making, and genomics. Key structural drivers include chronic disease prevalence affecting 60% of U.S. adults, an aging population requiring expanded services, evolving value-based payment models (40% of payments by 2022), and rising costs creating demand for scalable tech-driven efficiency. These trends are expanding the addressable market for healthtech while improving outcomes and accessibility.
