Overview
Even One Ventures is a venture capital firm that funds early-stage life sciences companies developing personalized therapies for life-threatening diseases. It operates with a patient-first investment approach, concentrating on pre-seed to Series B rounds to accelerate the development of medicines that may not otherwise exist. By investing across biotech and healthcare areas such as oncology, immune health, women’s health, rare diseases, and longevity, it supports teams from discovery to clinical development and commercialization. The firm differentiates itself by focusing on personalized, patient-tailored approaches and by building a portfolio that includes immune profiling, rescued oncology assets, personalized mRNA cancer vaccines, and custom T-cell therapies. Its goal is to get scientific advances quickly to patients, giving future patients a head start through ventures formed from the founder’s own health journey and deep scientific collaboration.
