Our take on data & enrichment
Data enrichment is where most GTM systems quietly break. Teams pay ZoomInfo for one thing, Apollo for another, and end up with three overlapping databases feeding conflicting records into the CRM. The result: contact records nobody trusts, outbound targeting that isn't targeting anything specific, and reporting that lags reality by weeks.
The nine tools below are the ones we actually deploy in client engagements. Clay isn't the answer to every enrichment problem — it's the orchestration layer that lets you use every other vendor smartly. Apollo, ZoomInfo, and Cognism remain critical for coverage in specific geos and personas. LeadIQ, Lusha, and PDL fill gaps others miss. Crustdata and Ocean are specialists you should know about if you sell into specific verticals.
The move that separates real practitioners from tool-list managers is knowing when to use which — and building a waterfall enrichment strategy so no single vendor becomes a single point of failure.
How we'd stack these tools together
Clay sits at the center as the orchestration layer. It calls Apollo, ZoomInfo, Cognism, LeadIQ, and PDL in a waterfall (primary vendor first, fallbacks after), pushes clean records into your CRM (HubSpot or Salesforce), and feeds enriched contacts into your outbound email tool (Smartlead) or LinkedIn outreach (HeyReach).
