WHY PICK IT- Waterfall enrichment queries 100+ providers sequentially and stops charging on failed lookups (since March 2026), so match rates beat any single database

- Claygent AI research agent automates web research (tech stacks, hiring signals, case studies) that would take SDRs hours per account

Choose Apollo.io if you want prospecting data, sequences and calling in a single tool at an SMB-friendly price.
Choose Clay if you need maximum data coverage and custom enrichment or AI-research workflows, and you're comfortable with a credit-based, more technical tool.
Bottom line: Teams wanting one affordable all-in-one pick Apollo; data-driven GTM teams building custom enrichment pick Clay — and many serious teams run both.
