Zavain Dar is a venture capital investor at Dimension who combines deep technical knowledge in software, AI, and biology to invest in "techbio" companies building foundation models for molecular interactions, with founders describing him as "natively bilingual" between machine learning and life sciences. He runs a concentrated investing approach with roughly 20 positions per fund and often leads sizeable checks so that he and Dimension can work closely with founders as "core architects," rather than holding many small, passive stakes.
