Playbook context
Choose Clay if
- 01Clay should own enrichment logic when signals matter.
Choose Apollo if
- 01Apollo is the cleaner first source for building target lists.
Use both if
- 01Keep both only when Apollo sources records and Clay enriches selected records.
Avoid both if
- 01Avoid running Clay and Apollo as parallel enrichment systems without a field-level ownership rule.
DECISION MATRIX
Winner by scenario
ScenarioClayApolloWhy
List source of truth-+Apollo is the cleaner first source for building target lists.
Custom account research+-Clay should own enrichment logic when signals matter.
Both tools already installed==Keep both only when Apollo sources records and Clay enriches selected records.
Cost delta
Overlap becomes a waste line unless roles are explicitly separated and reviewed in the cost model.
Switch risk
Medium: duplicate fields and credits become the migration risk.
Stack implications
- 01Treat Clay and Apollo overlap as the enrichment-boundary decision inside STK-A004; separate list sourcing from enrichment before credit usage scales.
