Logos Capital

What Logos Capital does

Logos Capital is a fundamental biotechnology-focused investment management firm founded in 2019 and headquartered in San Francisco, California, operating as Logos Global Management LP. The firm identifies and invests in transformative, first-in-class, and best-in-class biotechnology companies developing innovative therapeutics across both private and public markets, with disclosed participation in five financing rounds aggregating over $442 million between February 2025 and March 2026 spanning regenerative medicine, oral peptide therapeutics, clustering antibodies, AI-powered neurodiagnostics, and radionuclide cancer therapy. Its core differentiating technology is the proprietary Logos Analytics platform, a data science system that predicts clinical trial outcomes by modeling trial designs, replicating statistical analyses, and evaluating probability of success through advanced simulation and event tracking.

The firm is led by Managing Partners Dr. Arsani William, MD, MBA (CIO; previously drove biopharma portfolio expansion at Farallon Capital Management) and Dr. Graham Walmsley, MD, PhD (previously Principal and Portfolio Manager of the Vantage crossover fund at Versant Ventures, with involvement in BlueRock Therapeutics, Akero Therapeutics, Jecure Therapeutics, and Olema Pharmaceuticals). The broader team includes a CFO, General Counsel/CCO, VP Operations, Senior Analysts with clinical pharmacology and biomedical engineering expertise from Roche/Genentech, Amgen, Yale, and Peking University, plus an Investment Advisor who was Farallon's founding data scientist.

Logos Capital generates revenue through investment returns—management fees and performance carry—earned by deploying LP capital into transformative therapeutics. Go-to-market is sales-led and relationship-driven, targeting qualified institutional investors through direct outreach and IR channels ([email protected], phone lines at +1 (415) 801-4660 and +1 (415) 801-4670), with deal sourcing supported by the firm's proprietary analytical platform and rigorous clinical underwriting rather than external distribution.
