How to Choose

3 criteria for picking between 7 enrichment tools

Match the tool to the specific gap first: low email find rates need Clay's waterfall; stale CRM fields need Clearbit or Lusha scheduled enrichment; job-change blindness needs LeadIQ; anonymous web traffic needs Clearbit IP intelligence. Comparing all tools against a generic feature checklist produces worse selection than starting from the gap.

Delivery model determines operational overhead. Clay pushes enriched records directly to sequencers natively; Lusha webhooks update CRM on signal fire; LeadIQ's Salesforce package runs enrichment inside SFDC without data leaving. A tool requiring manual CSV export at each enrichment cycle multiplies overhead as volume scales.

⚠️

Test on your ICP before buying

Database size does not predict per-segment fill rates. A 1.8B-record database may return 40% fill on senior EU finance contacts while a smaller EMEA tool returns 75% on the same list. Test 100-200 contacts from your exact ICP across 2-3 candidates before selecting.
