About
Cosomil, Inc. (コウソミル株式会社) is a Japanese biotech startup developing single-molecule enzyme activity-based liquid biopsy technology for early disease detection and drug development support.

Their primary application is early detection of pancreatic cancer through blood tests. The company operates two business lines: early diagnostic drug development and pharmaceutical development support. Backed by investors including ANRI, Delight Ventures, and Coral Capital, Cosomil raised a Series A1 round in February 2026 to accelerate cancer screening blood test implementation in Japan and the US.
