Logos Capital
Logos Capital is a San Francisco healthcare investment firm that backs biotech companies from private rounds through their public life, and turns up repeatedly in cancer drug financings.
Overview
Logos Capital is a healthcare-focused investment firm based in San Francisco with offices in San Diego and Boston, investing in private and public biotechnology companies with a data-driven, clinically grounded approach. It appears as a participant in several of the sourced oncology rounds in OnCo, typically as part of a syndicate rather than as the company-creating lead. Portfolio links here are derived from the startup records that name it; the firm's own site describes its team and approach rather than listing a full portfolio.
