Clay vs Apollo.io

Evidence coverage

• Both products' official identity is verified directly from their own homepages: Clay positions itself as data-enrichment and agentic-workflow infrastructure for go-to-market teams, while Apollo.io positions itself as a unified AI sales platform combining B2B contact data, outbound automation and deal execution.
• The two overlap on data enrichment and outbound automation but differ in scope — Apollo bundles a large first-party contact database, while Clay is built to orchestrate and enrich data from many external sources. No capability, accuracy or ROI winner is asserted; that requires field-level evidence this site does not yet have for either product.
