Evidence for every value

Each field says how confident we are and which sources back it. Ask for evidence and you get the quote and the page or record it came from.

Sources you can check

The company's own site, Wikidata, GLEIF, UK Companies House, SEC EDGAR and the national registers of France, Norway, Czechia and Finland. Headcount comes from filed accounts and filings where there are any.

Stored or fresh

A company we already have comes back in milliseconds. One we don't is enriched on the spot, usually in 20 to 30 seconds, or followed by polling or a signed webhook.

A miss is free

An enrichment that finds no company costs nothing. Reading a stored record costs a tenth of an enrichment.
