About RainPath

RainPath is reinventing how we diagnose human tissue.

Today, pathology labs still rely on complex chemical staining and manual workflows to detect disease. We build 100% software-based tools that replicate the results of immunohistochemistry (IHC) in seconds — no reagents, no delays, no lab work.

Our mission: simplify, accelerate, and standardize diagnostic workflows using AI, advanced imaging, and deep medical expertise.

We Combine Two Major Innovations

• A virtual staining and biomarker detection module, based entirely on image data
• A workflow digitization module, assisting pathologists in generating structured reports, automated pre-screening, and ensuring traceability from slide to diagnosis
  
  

With RainPath, We Enable

• Instant results instead of multi-day delays
• Costs divided by 100
• A fully digital, scalable, and standardized diagnostic pipeline
  
  

This is a paradigm shift in pathology — and RainPath is leading it.
