# Clay vs Apollo.io

Clay is **enrichment infrastructure you design yourself**, orchestrating 150+ providers behind custom waterfalls. Apollo is an **all-in-one platform**: its own 275M-contact database plus multi-provider waterfalls, sequencing, and a dialer under one bill. If custom data workflows and match rates justify the build, Clay wins. If you want contacts and outreach live in an afternoon, Apollo does.

## The decision

Both source and enrich B2B contacts, and both now run waterfalls. The split is build-it-yourself depth versus all-in-one convenience: Clay is a data workbench, Apollo is a platform.
