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.
Arda Therapeutics is a San Carlos, California biotech building precision biologics that eliminate the specific cells driving chronic disease rather than tinkering with the proteins those cells produce. Using a single-cell data discovery engine, Arda maps disease-specific cell states, pinpoints their surface markers, and designs targeted therapies that deplete only the harmful cells while sparing healthy tissue. Founded in 2021 by former Calico scientist Adam Freund, the company is applying lessons from oncology to fibrosis, autoimmune, and metabolic disease, backed by a $43M Series A led by a16z Bio + Health.
