List Building

Build targeted account lists for campaigns using signal data, CRM, enrichment tools, and hypothesis-driven search criteria.

Key Difference from Extruct

Extruct uses their proprietary search API (Instant, Lookalike, Deep Search). We use:

1. Signal Engine — sources detecting buying signals across target accounts
2. HubSpot CRM (MCP connected) — existing contacts, past engagement, lifecycle stage
3. Clay (MCP connected) — company enrichment, contact data, waterfall enrichment
4. Existing campaigns — account JSONs with domains and metadata
5. Manually curated lists — CSV imports from events, partner data, purchased lists

When to Use

• After hypothesis-building (search angles guide targeting)
• When creating a new campaign and need target accounts
• When expanding an existing campaign with lookalike accounts
