Data Engine
Anchored in human reality. One of the most comprehensive spatial transcriptomics databases available today - 3,000+ patient samples and 100M+ spatially resolved cells.
Decoding Diseases with Spatial Intelligence
Revolutionizing Drug Discovery with Spatial Omics and AI-Driven Virtual Tissue Pharmacology.
THE TRANSITION
Biology happens in space
Traditional bulk approaches miss the spatial context of disease. Portrai integrates spatial biology with single-cell information to decode the architecture of the Tumor Microenvironment (TME).
- 3,000+
- Proprietary tissue samples
- 100M+
- Spatially resolved cells
- 20+
- Cancer & normal tissue types
THE PORTRAI PLATFORM
One platform, Three engines A self-reinforcing flywheel
Data, prediction, and validation — each engine makes the others sharper. Every new patient sample refines our models. Every validated asset improves future target discovery.
Prediction Engine
In-silico prediction with spatial precision. Microscopic-PK, Microscopic-PD, and Vision-Gene-Language (VGL Suite) decode the tumor microenvironment for target and toxicity assessment.
Validation Engine
Modality-aware validation. Translate AI insights into physical assets — first computationally, then in tissue, then in vivo. ADC- and RPT-ready.
PIPELINE
Transforming insights into medicines
Novel targets from Portrai ATLAS, translated into modality-fit asset candidates across ADC and RPT programs.
- Discovery-stage POR Series targets (POR001, POR003, POR006)
- Modality-fit asset candidates across ADC and RPT programs
- Undisclosed targets, data room on request
