Previse is a biotechnology company based in Baltimore, Maryland, focused on advancing cancer detection and prevention, starting with esophageal cancer. Its approach relies on a routine test augmented by DNA biomarkers to identify disease earlier, aiming for a test that is convenient, affordable, and accurate enough to be used before symptoms appear. The work behind the technology stems from decades of research at the GI Early Detection Biomarker Lab at Johns Hopkins University School of Medicine.

Its potential customers include patients at risk and the healthcare providers who serve them, with the goal of delivering timely answers about cancer development and severity. Positioned in the biotechnology research sector, Previse seeks to complement or replace aspects of current detection methods that are invasive or costly. In May 2025, Castle Biosciences announced it would acquire Previse.
