CiberMed is a stealth biotechnology company started by industry veterans and Stanford University professors.

Our mission is to be the industry leader in the discovery and measurement of biomarkers using our patented technology which uses novel in silico cell sorting to determine cell proportions and gene expression.


Biomarker Discovery

CiberMed applies a variety of data science techniques including machine learning that lead to biomarker discovery. The CiberMed data science team develops biomarker models using immune cell data quantified by iSort™


iSort™ is a digital cytometry. It quantifies immune cell subsets in silico using gene expression data. The core technology is based on CIBERSORT and CIBERSORTx platforms, that were originally developed at Stanford University, and licensed to CiberMed.

Advantages of iSort

iSort™ digital cytometry provides highly accurate and robust cell subset enumeration from clinical biospecimens.

  • Cost-effective and high-throughput

  • Highly reproducible

  • Unaffected by tissue dissociation

  • Applicable to fresh, frozen, and fixed tissues

  • Applicable to pre-existing gene expression data
