Corporate intelligence for investigative reporting
SupplySignal maps corporate ownership structures and individual appointment histories from Companies House data, giving journalists and researchers the network picture that used to require days of manual registry searching.
Public registry data, structured automatically
Companies House is a rich public data source. The challenge is that navigating it effectively requires working through company-by-company, page-by-page, building a mental map of connections that is time-consuming and easy to miss connections in.
SupplySignal automates that structure-building process. The same public data, assembled into a traversable corporate network map, with sanctions and enforcement overlays applied. What takes hours manually takes minutes on SupplySignal.
Every data point on the map is sourced from Companies House or official government registers. There is no proprietary or opaque data methodology. The map reflects what is in the public record.
Company network mapping
Map the full corporate network behind any UK company. Directors, PSCs, connected entities and related businesses, all drawn from Companies House public data and visualised in an interactive map.
Individual appointment history
Search any person by name to surface every Companies House appointment across their career, including dissolved companies and historical roles that may not appear in a standard company search.
Connection paths between entities
Find the most direct path between any two individuals or companies on the map. Useful for establishing indirect connections that are central to an investigation.
Sanctions and enforcement flags
Sanctions designations, FCA warning notices and director disqualification orders surface automatically on every map. No separate sanctions database required.
How this works in practice
Mapping ownership behind a company in a story
Rather than working through Companies House company by company, search the entity and let SupplySignal build the ownership map. Directors, PSCs and connected companies surface in one view.
Tracing an individual across corporate networks
An individual's full Companies House history, including connections you might not know to search for, appears on a person map. Patterns of behaviour across multiple companies become visible quickly.
Establishing connections between parties
Where two parties in a story need to be shown as connected, the Find Path feature identifies the shortest connection through the corporate network, using public registry data as the source.
Transparent data sourcing
All corporate mapping data is sourced from Companies House public registers and official government enforcement lists. SupplySignal does not generate or infer connections, it structures what is already publicly available. Every data point can be traced back to its source record.
