# Is Clay worth it, and what do companies actually use it for?

Clay is in about 44% of high-growth GTM stacks as a customer-owned tool, and closer to two-thirds once partner-run instances are counted — the fastest adoption curve in the category. It is used as an orchestration layer over multiple data providers, not as a single enrichment source.

No enrichment incumbent comes close on trajectory: ZoomInfo sits around 35% and Apollo 26% in the same panel. The practical pattern is Clay for coverage and waterfall logic, with scoring rules kept inside Clay so the enrichment and the qualification logic stay in one place.
