The spatial map of human biology
We are mappingthe human body, cell by cell.
Search it. Zoom in. Find your way. Now for human tissue. We turn spatial omics data into one navigable atlas, so you can see where disease begins, not only what it expresses.

Why now
Every street on Earth is mapped. The human body still runs on scattered sketches.
Every spatial experiment charts a small piece of human tissue. Most of those charts sit in separate files, formats and labs. We join them into one map that you can search, compare and zoom, from the whole organism down to a single transcript.

The atlas
Every discovery gets a coordinate.
Findings are pinned to the place in the body where they happen. Turn the body. Hover or tap a marker to see what is already on the map.

Every scale
Zoom in until the biology explains itself.
- 01 · Organism · 1 m Start with the patient. Every sample keeps its place in the body, its donor and its disease context.
- 02 · Tissue · 1 mm Open the tissue. Raw data from any platform lands in one common spatial format, quality checked.
- 03 · Cells · 50 µm Meet the neighbours. Each cell is segmented, typed and placed next to the cells it talks to.
- 04 · Molecules · 5 µm Read the street signs. Every transcript keeps its coordinate. Expression becomes an address.

How it works
One map. Two ways in.
The survey TESSERA
You have spatial data.
Hand us raw data. Our end-to-end engine charts it and returns publication-ready results, fully reproducible.

Use cases
Built for teams who cannot afford to guess where.
Target discovery
Mine the atlas for spatial biomarkers and therapeutic targets.
Virtual cohorts
Assemble disease cohorts from existing data. No wet lab, no waiting.
Pilot validation
Compare your first slides against thousands of reference samples.
Tumour microenvironment
Map immune niches and exhaustion at subcellular resolution.
Neurodegeneration
Place rare cell states inside lesions across many donors.
Publication-ready analysis
Figures, interactive reports and queryable data objects.
Results
Already on the map.
31 MS patients. 200+ tissue sections. A new disease state discovered.
We partnered with Cambridge to process fragmented spatial cohorts from post-mortem brain tissues at scale. The result: identification of Disease-Associated Radial Glia-like cells in chronic MS lesions.
“By scaling this spatial analysis, we successfully identified DARGs in chronic active lesions - uncovering a novel cellular axis for disease pathobiology and potential therapeutic intervention.”

- Cancer types
- Xenium
- Subcellular platform
Two cancer types. Subcellular spatial resolution. An immunosuppressive niche mapped.
We partnered with SOTIO Biotech to process complex Xenium spatial cohorts comparing cervical and head and neck cancers. The result: identifying dense regulatory T cell populations and localized exhaustion signatures as key drivers of immunosuppression in cervical cancer.
“Generating the spatial data was only the first step. Carta Genum provided the dedicated bioinformatics capacity we needed, turning our complex datasets into clear, publication-ready biological insights.”
Help us draw the map.
We work with a small number of labs at a time. Let's see if we're a fit.
