Gordian Biotechnology
Gordian Biotechnology is a South San Francisco in vivo drug discovery company building a high-throughput screening platform that tests hundreds of gene therapies simultaneously inside animals that naturally develop age-related diseases. By pairing 'patient avatar' models with single-cell transcriptomics and machine learning (a stack the company calls Mosaic Screening + Pythia), Gordian aims to predict human clinical outcomes earlier and cure complex diseases of aging.
Francisco Leport
Francisco Leport is the co-founder and CEO of Gordian Biotechnology, a South San Francisco-based company pioneering high-throughput in vivo drug discovery for age-related diseases. Trained as a physicist at Stanford, Leport pivoted from particle physics and energy tech into biotech, driven by a lifelong fascination with longevity sparked by his mother's fruit fly research. Gordian's signature 'mosaic screening' platform uses gene therapy vectors and single-cell RNA sequencing to test hundreds of therapies simultaneously in single animal models, with an AI system called Pythia scoring results against human disease signatures - achieving 80% accuracy in predicting clinical outcomes. The company raised a $60M Series A in April 2024, backed by Founders Fund, Gigafund, and The Longevity Fund, and in early 2026 announced a research collaboration with Pfizer to accelerate obesity drug discovery.
