Pair a primary database (Apollo/ZoomInfo) with a workflow tool (Clay) for custom enrichment, and an AI research layer for unstructured signals (hiring, news, product). That's the modern stack.
Layer 1 — Database enrichment
Firmographic, technographic, and contact data from primary sources.
Layer 2 — Workflow enrichment
Custom signals built via Clay or similar — combining multiple sources into bespoke fields.
Layer 3 — AI research
Unstructured signals: company positioning, recent press, product launches, hiring trends.
How to combine
Database fills the structured fields; AI research adds the context for personalization.
How SendroAI Fits In
SendroAI's AI Research Engine is the third layer — automated, per-prospect, fed into copy generation.
