PSNL

Personalis, Inc.

A cancer genomics company that reads the full DNA of a patient's tumor to help doctors spot cancer returning earlier than scans can. Its flagship test, NeXT Personal, is a liquid biopsy that hunts for tiny traces of tumor DNA in a blood sample. Founded in 2011 by Stanford University researchers, the company's name comes from "personalized" medicine — tailoring cancer care to each patient's unique genetic makeup.
