Clay is a data enrichment and outreach platform that pioneered the waterfall enrichment model. Clay holds a 4.6/5 rating on G2 based on 200+ reviews, with users praising its flexibility and integrations. Instead of relying on a single data source, Clay queries multiple data providers (75+) in sequence until it finds the data you need. This approach maximizes coverage by combining data from providers like Apollo, Clearbit, Hunter, ZoomInfo, and others. See Clay reviews on G2.
Clay's spreadsheet-like interface lets users build enrichment workflows visually. Each column can trigger a different enrichment, and AI features (Claygent) can research companies and write personalized outreach. Clay integrates with outreach tools like Instantly, Smartlead, and HubSpot.
However, Clay's credit system can be expensive. Each enrichment action consumes credits, and waterfall enrichments that query multiple providers use more credits per lookup. The platform also adds complexity: you are managing multiple data provider connections, each with different quality characteristics.
