HealthCare Ventures

HealthCare Ventures is a life science-focused venture capital firm founded in 1985 and headquartered at 47 Thorndike Street in Cambridge, Massachusetts. Over more than 35 years, the firm has invested $1.6 billion in more than 100 therapeutic, diagnostic, device, and healthcare technology companies, establishing itself as one of the longest-running healthcare-dedicated VC firms in the United States. Harold Werner serves as Managing Director, and the firm employs approximately 11 people. HealthCare Ventures focuses specifically on pre-clinical or early clinical stage companies with transformative potential in patient care, deploying check sizes in the $3 million to $10 million range across Seed, Series A, and Series B rounds and leading rounds. The firm has made at least 32 tracked investments according to public databases. Portfolio sectors span therapeutics, diagnostics, medical devices, and healthcare technology. A recent notable portfolio exit was Paige, an AI-powered cancer diagnostics company, which exited on August 22, 2025. HealthCare Ventures takes a hands-on approach that goes beyond providing capital: the team actively helps manage portfolio companies, providing operational guidance, strategic input, and scientific expertise throughout the development journey from pre-clinical work to commercialization. The firm's nearly four decades of continuous operation in life science venture investing give it institutional knowledge and relationships across the clinical, regulatory, and commercial ecosystem that span multiple full innovation cycles in biotechnology and medical devices.
