Methodology

Data provenance & methodology

This page transparently documents which data sources we aggregate, how often we refresh, how we enrich the data, and where our coverage stops. For citations, journalism and academic use.

Data sources

What we do NOT promise

·Completeness at the small end: very small proceedings without a §9 publication (consumer insolvencies, natural persons with no business tie) are typically not captured.
·Real-time freshness: our hourly sync trails the official publication by 15–60 minutes at median.
·Causality of distress signals: Wayback decay or Trustpilot ratings are correlations, not proof of payment difficulty.
·AT/CH coverage: Austria (Ediktsdatei + Firmenbuch) is targeted for Q1 2027; Switzerland (SchKG) is a separate product.
·AI-generated content: deep summaries and Deal Playbooks are LLM outputs. Use as supplement, not as legal advice.
