Cheiron is a Stanford-based AI company building the AI-native operating system for drug development.
Biopharma knowledge work is structurally fragmented. Critical decisions depend on stitching together evidence across literature, clinical trials, regulatory precedent, and patentsspread across disconnected systems. Cheiron replaces this paradigm with a unified intelligence layer: our proprietary Lifesciences Knowledge Graph (LKG), which integrates and structures these data sources into a single, continuously evolving system of record.
On top of this foundation, Cheiron deploys workflow-native AI agents that execute real-world R&D, clinical, and regulatory tasks end-to-endwith full traceability and scientific rigor.
Since launching in 2024, Cheiron has achieved rapid global adoption. In Korea, we reached 22% of the biopharma knowledge workforce across 200+ organizations within six months. In the United States, within two months of launch, we onboarded thousands of professionals across hundreds of biopharma companies, driven by strong organic demand.
