About
Craif is a Japanese biotech company spun out of Nagoya University in 2018, pioneering non-invasive early cancer detection through urinary microRNA analysis. The company's proprietary biomarker platform, NANO IP (NANO Intelligence Platform), combines advanced microfluidics, multi-microRNA profiling, and AI algorithms to detect cancer-specific signals in urine samples. Its flagship product, miSignal Scan, enables urine-based cancer risk screening developed through collaborative research with approximately 50 major Japanese university hospitals and cancer research centers. Craif expanded to the United States in 2025, establishing a bioAI lab in San Diego and being accepted into Johnson & Johnson's JLABS incubator. The company is advancing medical device development for pancreatic cancer early detection in both Japan and the US.
