Lead Intelligence

B2B Lead Intelligence Methodology

Comprehensive framework for discovering, enriching, scoring, and prioritizing B2B leads using 8 data sources. All API calls use wrapper scripts in ${CLAUDE_PLUGIN_ROOT}/scripts/.

Data Source Hierarchy

Query sources in this order — most reliable and cost-effective first:

1. Apollo.io — Company firmographics, contacts with direct phone/email, org charts, revenue, tech stack, funding. Script: apollo-api.sh
2. Hunter.io — Email discovery with confidence scores, domain search, verification. Script: hunter-api.sh
3. Google Places — Business verification, address, phone, ratings, reviews. Script: google-places-api.sh
4. SerpAPI — Web/news/jobs search, LinkedIn profiles, hiring signals. Script: serp-api.sh
5. GitHub — Tech stack detection, team size, open-source activity. Script: github-api.sh
6. SEC EDGAR — Public company financials (10-K, 10-Q), revenue, earnings. Script: sec-edgar-api.sh

Enrichment Pipeline

For every B2B lead, run this pipeline:

1. Discover

• apollo-api.sh company-enrich --domain <domain> → company firmographics
• google-places-api.sh find "<company name> <city>" → verify existence, get address/phone
• hunter-api.sh domain-search <domain> --seniority executive → executive emails

2. Enrich

• apollo-api.sh org-chart --domain <domain> → decision makers with titles, emails, phones
• hunter-api.sh find-email --domain <domain> --first <name> --last <name> → specific contact emails
• serp-api.sh news "<company>" --num 10 → recent news and signals
• serp-api.sh jobs "<company>" → hiring activity
• github-api.sh languages <org> → tech stack
• sec-edgar-api.sh search "<company>" → financial data (public companies)

3. Score

Apply ICP scoring, intent scoring, and priority ranking. See references/icp-framework.md and references/signal-weights.md.

4. Output

Format results as a structured lead report with all gathered fields, scores, and recommended next actions.

Decision-Maker Scoring (1-10)

Factor	Points
C-level title (CEO, CTO, CFO, COO)	+4
VP / SVP title	+3
Director / "Head of" title	+2
Manager title	+1
Budget-related keywords in title (Procurement, Purchasing, Vendor)	+1
3+ years tenure at company	+1
Department matches your product category	+1

Verification Protocol

Never trust single-source data. Cross-reference:

• Email confidence: Hunter.io provides scores (accept >80%, verify 50-80%, reject <50%)
• Phone verification: Google Places confirms business phone, Apollo for direct dials
• Title validation: LinkedIn + company website + Apollo agreement
• Recency check: Prefer data updated within 6 months

Data Quality Standards

Data Type	Accept (use directly)	Verify (cross-reference)	Reject (discard)
Email	>80% confidence	50-80% confidence	<50% confidence
Phone	Apollo direct dial	Google Places business	Unverified
Title	Multi-source match	Single source	>12 months old
Revenue	SEC filing	Apollo estimate	Unverified guess

API Rate Limits

API	Monthly Limit	Per-Request Cost	Strategy
Hunter.io	25 (free tier)	1 request	Verify top leads only, cache results
Apollo.io	900 credits	1 credit per person/company	Batch wisely, org-chart for bulk
SerpAPI	5000 searches	1 search	1 per query type, cache results
Google Places	~11K (free $200 credit)	$0.017	Use for verification only
GitHub	5000/hour	Free	Use freely
SEC EDGAR	Unlimited	Free	Rate limit to 10 req/sec

Always prioritize free sources first. Use paid APIs (Hunter, Apollo, SerpAPI) only when free sources don't have the data.
