Karius is a Redwood City, California life-sciences company that turns a single blood draw into a broad infectious-disease diagnosis. Its flagship Karius Test uses microbial cell-free DNA (mcfDNA) sequencing, metagenomics and AI to detect more than 1,000 pathogens - bacteria, DNA viruses, fungi and parasites - often within a day of receiving a sample. Founded in 2014 out of Stephen Quake's lab at Stanford, the company aims to give clinicians a fast, non-invasive alternative to invasive biopsies and slow cultures, with a focus on the immunocompromised patients who need answers most urgently.
eGenesis is a Cambridge, Massachusetts clinical-stage biotechnology company using multiplex CRISPR gene editing to engineer pig organs that the human body will accept. Its EGEN platform makes dozens of edits to a porcine genome at once - removing pig antigens, adding human genes, and inactivating embedded retroviruses - to create kidneys, livers, and hearts intended to ease the global organ shortage. In 2024 its lead candidate became the basis of the world's first gene-edited pig kidney transplant in a living patient, and in 2025 the FDA cleared it for a formal clinical trial.
