Enrichment adds what a form or a CRM record is missing: company size, industry, location, job title, a verified email or phone number. It makes lead scoring, routing and segmentation possible without asking prospects twenty questions.

Three kinds of data

Trade and shipment dataFinding importers, exporters and suppliers by productVolza, ImportGenius

Read what is data enrichment and how to find importers and suppliers with trade data.

Signals and public web data

Two more sources feed enrichment. Sales platforms watch for buying signals such as job changes and intent; web data providers collect public search results and prices at scale for analysts. Both bring privacy and terms-of-use obligations: check them for your market. Not legal advice.
