Two pieces of infrastructure no one in EU autonomy distribution has built. Both compound into data moats. Early-access partners get scored BOMs and Build Graph contributor seats first.
A live 0–100 procurement-risk score on every SKU and every uploaded BOM. Combines EU-content %, China single-source dependency, export-control classification, lead-time volatility, substitute availability, and live sanctions screening into a single number a procurement team can act on.
Every BOM uploaded sharpens the model. After 500 BOMs, D27 owns the most accurate EU autonomy supply-chain risk dataset in existence — that's a data moat, not a feature.
A public, contributable registry of real machine builds. Drones, robots, UGVs, inspection systems, humanoids — every build is a structured data object with verified components, software stack, EU-content %, and build status.
Hugging Face's model hub created gravity because the artifact was free to share and the discovery was structured. Build Graph does the same for physical machines. Procurement can search "EU warehouse inspection robot with thermal payload and ROS2" and get real builds from real builders — not search results.
