# System Atlas

> A free public registry of how organizations are built: companies, agencies and nonprofits, each mapped the same way (its parts, the software it runs, how work and money flow), with the source behind every fact. Figures quoted from a source are marked as quotes; anything inferred is labelled as inferred, with its confidence.
