Clay

Enriches lead lists with data from many sources and AI research agents.

Supervision needed: Medium Tables run on their own, but enrichment data needs spot checks before it goes into outreach.
Where it tends to fail: Wrong or stale contact data, and credits spent on rows you did not need.
Pricing: See pricing page; plans changed more than once in 2026. Pricing page (Checked Oct 2026)

The supervision level and failure notes are our editorial judgment from how these tools are built and used, not test results or ratings. Your setup may differ.
