Clay

Clay is a data enrichment powerhouse that combines 75+ data providers into a single interface. It's designed for sales teams and agencies who need to build highly targeted prospect lists with verified contact information.

The platform excels at waterfall enrichment, automatically trying multiple data sources until it finds the information you need. This dramatically increases match rates compared to single-source tools.

Clay integrates with CRMs, outreach tools, and allows for complex filtering and segmentation. While it has a steeper learning curve, the power it offers is unmatched for serious prospecting operations.

Clay is the Swiss Army knife of prospecting tools. After using it for 6 months with our agency, the depth of data we can access is incredible. The waterfall enrichment alone has saved us thousands in credits that would be wasted on failed lookups.

Setup isn't trivial - expect to spend a few hours learning the interface and setting up your first workflows. But once you understand the table-based approach, building complex prospect lists becomes almost enjoyable.

The pricing is steep at $99-299/month, but for agencies doing serious outbound, the ROI is clear. We've seen enrichment rates of 85%+ compared to 50-60% with single-source tools.

One concern: some of Clay's automation features do carry LinkedIn ToS risk. We recommend using it primarily for data enrichment and building lists, then using safer tools for actual outreach.

Verdict: Essential for agencies and sales teams with serious prospecting needs. Overkill for solopreneurs.
