Investment thesis
Waterline Ventures concentrates exclusively on healthcare, investing in early-growth technology and service-enabled technology companies in that sector. The firm believes success in healthcare demands deep domain expertise built on extensive industry experience, and it maintains a disciplined single-market focus. It emphasizes building lifetime relationships with entrepreneurs, aiming to back founders across multiple ventures throughout their careers. Waterline also stresses capital efficiency, working with founders to craft financing plans appropriate to each company's needs rather than assuming every idea requires large amounts of capital. Drawing on decades of investing and operating experience, the firm supports founders through its network while letting them run their businesses.
