Town Hall Ventures closed a $440 million fund to invest in startups using AI to expand healthcare access and outcomes for underserved populations. The firm targets companies that combine clinical workflows with scalable technology to reduce disparities. The sizable fourth fund signals growing LP appetite for healthtech strategies that pair clinical validation with data-driven scalability. Town Hall’s focus on underserved markets differentiates it from generalist healthtech funds and suggests continued funding flow into care-delivery innovation. For portfolio companies, the new capital pool can accelerate clinical validation, regulatory navigation, and deployment in safety-net settings where adoption barriers have historically impeded scaling.
