RainPath vs Woebot Health

RainPath builds software for anatomopathology labs that replaces slow chemical staining workflows and cuts down on administrative busywork. Its virtual staining turns unstained biopsy slides into diagnostic-quality H&E and IHC images in seconds, without toxic reagents. Pathologists get faster, more consistent tissue images while labs spend less on chemicals and equipment.

The company combines optical imaging with deep learning models trained on paired tissue datasets. Its virtual staining covers label-free H&E generation, H&E-to-IHC stain translation, and in-silico multiplex biomarker prediction from standard H&E slides. RainPath was named among the 100 most promising AI startups at Raise Summit 2025 and is part of the Paris Saclay Cancer Cluster.

Beyond staining, RainPath Software automates lab operations: RainPath Bons handles order registration with French health system integrations (INSi, ADRi, eSant??), and RainPath Compte Rendu pre-drafts pathology reports with voice dictation built in. RainPath Voice is a desktop medical dictation app for macOS and Windows that works inside any clinical software. Labs host data on HDS-certified servers in France with GDPR compliance.
