Citronnier Atlas
A longitudinal biological intelligence platform for measuring how an individual's biology changes over time.
Overview
Citronnier Atlas is the company's flagship longitudinal omics platform. It connects minimally invasive biological samples with molecular profiling, imaging, phenotype, and intervention history to build a reusable personal timeline. The first use case is skin biology: establish a baseline, record skincare or procedures, and compare within-person biological change through repeat sampling. High-dimensional technologies such as 10x Genomics support discovery, while validated signatures are intended to move into lower-cost, repeatable assays. Atlas is currently in proof of concept and is not a diagnostic or treatment product.
Highlights
- • Longitudinal profiles that become more useful as repeat samples are added
- • Unified timeline for molecular data, images, phenotype, and intervention history
- • Skin biology as the first use case, focused on within-person change rather than a single skin-age score
- • 10x Genomics Chromium, Visium, and Xenium as discovery and validation engines
- • Reproducible ingestion, quality control, provenance, and report-generation pipeline
- • A path from high-dimensional discovery to lower-cost, repeatable targeted assays
Details
- • 2026 proof of concept: three participants from sample collection through prototype report
- • Initial biological dimensions include skin barrier, inflammation, extracellular-matrix remodeling, and cellular senescence
- • Core data asset: paid longitudinal sample pairs linked to phenotype and intervention history
- • Research-stage outputs clearly communicate evidence level, uncertainty, and limitations
- • No disease diagnosis, treatment direction, or validated biological-age claim at the proof-of-concept stage
