RainPath vs Docus

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.

Docus is a health technology platform built for diagnostic labs, doctors, and patients. Its homepage positions the product as an AI layer for modern diagnostic labs, with modules for interpretation reports, follow-up recommendations, compliance checks, digital requisitions, and context-aware assistants.

For labs, Docus turns raw test results into clinical reports for doctors and patient-friendly explanations. It supports routine panels, infectious disease, pharmacogenomics, and pathology workflows. Labs can connect via API or HL7 into an LIS, CRM, or EHR, or use branded Docus interfaces without integration.

Doctors get a clinical decision support platform with an AI medical assistant, research assistant, lab test interpretation, AI-generated SOAP notes, and patient messaging with AI auto-complete. Plans scale by number of patients managed, and the first patient is free.

Patients use the AI Health Assistant to chat with a personal AI Doctor, upload lab results for interpretation, run a symptom checker, and request second opinions from a network of 350+ doctors across 30+ specialties.

Docus states it meets HIPAA, GDPR, and SOC 2 requirements, encrypts data in transit and at rest, and does not require personally identifiable information for core workflows. The company is based in Wilmington, Delaware.
