Lead Research Process

Step 1: Define ICP (Ideal Customer Profile)

Ask or infer:

• Target titles: What roles are you selling to?
• Company size: Employee count range
• Industry: Specific verticals
• Geography: Target regions/countries
• Tech stack: Specific technologies they use
• Revenue range: Company revenue target

Step 2: Build Search Query

Translate ICP into Apollo search filters. Run multiple searches with variations:

• Different title variations (VP Marketing = VP of Marketing = Vice President, Marketing)
• Adjacent roles (CMO, Director of Marketing, Head of Growth)
• Company size tiers separately

Step 3: Enrich Results

For each prospect found:

1. Note their current title, company, and location
2. Enrich their company domain for additional context
3. Look for mutual connections or shared background

Step 4: Qualify & Prioritize

Score leads on:

Factor	Weight	Criteria
Title match	30%	Exact title vs. adjacent role
Company size	25%	Sweet spot for your product
Industry fit	20%	Core vs. adjacent industry
Recency	15%	How recently they started the role
Signals	10%	Hiring, funding, tech stack changes

Step 5: Output Lead List

Format results as:

# Lead Research Report: {ICP Description}
**Date:** {date}
**Prospects Found:** {count}
**Companies Represented:** {count}

## Top Prospects

| # | Name | Title | Company | Employees | Industry | Score |
|---|------|-------|---------|-----------|----------|-------|

Important Notes

• Apollo rate limits are strict (~600/hour). Batch requests and cache results.
• Some endpoints require a paid plan. Handle 403 responses gracefully.
• Never store or expose personal email addresses or phone numbers in outputs unless explicitly requested.
• Respect opt-out lists and GDPR/CAN-SPAM compliance.
• Use enrichment data for personalization, not for unsolicited spam.
