Programmatic prospecting and enrichment: 50+ data sources and AI in one workflow.
Teams building signal-driven outbound or automating enrichment and CRM hygiene.
Data Enrichment & Signals
What Clay is.
Clay is a data enrichment and automation platform that pulls from dozens of providers and layers AI on top, so you can build highly personalized, signal-driven outbound and clean CRM data at scale.
It's the engine behind modern lead-gen and RevOps data quality when 'spray and pray' won't cut it.
Clay is best understood as a programmable layer over the entire enrichment category rather than a data provider itself, which is why its waterfalls can outperform any single source on coverage. That flexibility is also its risk: with no guardrails, teams build sprawling, credit-hungry workflows that are hard to maintain and easy to over-personalize. The tools that succeed with Clay treat it as owned infrastructure with a clear ICP and a defined use, not an open-ended playground.

Clay: common questions
Is Clay worth it for B2B?+
Yes for teams building signal-driven outbound or automating enrichment and CRM hygiene at scale. Clay is powerful precisely because it aggregates 50-plus data sources with waterfalls and layers AI on top, giving fill rates and personalization a single source cannot. For simple list-building, it is overkill versus a tool like Apollo.
Clay vs Apollo, which should we use?+
Clay wins on enrichment depth and custom automation via multi-source waterfalls; Apollo is simpler, cheaper, and ships its own database and sequencing. They are complements more than rivals: Apollo for affordable volume, Clay when you need accuracy, custom signals, or workflows that stitch many providers together. The catch is Clay demands real setup skill.
How much does Clay cost?+
Clay uses credit-based pricing on tiered plans, where every enrichment call and data lookup consumes credits that can scale quickly with volume and the number of providers in a waterfall. Costs are usage-driven, so a heavy program can climb fast. Model your credit burn before scaling workflows.
Who should NOT use Clay?+
Small teams that just need basic prospect lists, or anyone without the time to learn its spreadsheet-style automation. Clay has a steep learning curve and is powerful enough to over-engineer if unmanaged. If you cannot dedicate someone to build and maintain workflows, a simpler tool will deliver value faster.
