insol
Research data on insolvency proceedings of German firms
insol is a longitudinal research database of
German firm insolvency proceedings and the official filings
associated with them. It covers firms and other registered
economic entities that can be identified through German
register identifiers. We provide two data products:
- Aggregated daily data on new insolvency cases, grouped by courts and WZ 2008 industry sectors (if available). These data can be accessed freely via our API.
- Detailed micro-level research data on insolvency proceedings. Available only for non-commercial academic use.

Immutable history
Published releases remain available through the API. Later schema changes do not alter the data or structure of historical releases.

Each release records the code version that produced it. Historical inputs are used to reproduce and verify past releases.
