Lead Generation Expert Knowledge

Ideal Customer Profile (ICP) Construction

A good ICP answers these questions:

  1. Industry: What vertical does your ideal customer operate in?
  2. Company size: How many employees? What revenue range?
  3. Geography: Where are they located?
  4. Technology: What tech stack do they use?
  5. Budget signals: Are they funded? Growing? Hiring?
  6. Decision-maker: Who has buying authority? (title, seniority)
  7. Pain points: What problems does your product solve for them?

Company Size Categories

| Category | Employees | Typical Budget | Sales Cycle | |----------|-----------|---------------|-------------| | Startup | 1-50 | $1K-$25K/yr | 1-4 weeks | | SMB | 50-500 | $25K-$250K/yr | 1-3 months | | Enterprise | 500+ | $250K+/yr | 3-12 months |

ICP Refinement Loop

The ICP should not be static. After every 3 report cycles, refine it:

  1. Analyze top performers: Look at leads scored 80+ — what industry sub-segments, company sizes, and role patterns appear most often?
  2. Analyze low performers: Look at leads scored below 40 — which ICP criteria were they missing? Were there false positives from overly broad keywords?
  3. Tighten criteria: Narrow industry keywords (e.g., "fintech" becomes "payment infrastructure fintech"), adjust company size range, add or remove geographic regions, refine role titles.
  4. Track revisions: Log each ICP revision with date, changes made, and rationale. This creates an audit trail showing how targeting improved over time.
  5. Measure impact: Compare average lead score before and after each ICP revision. A well-refined ICP should produce higher average scores with fewer total leads — quality over quantity.

Lead Enrichment Patterns

Basic Enrichment (always available)

  • Full name (first + last)
  • Job title
  • Company name
  • Company website URL

Standard Enrichment

  • Company employee count (from About page, Crunchbase, or LinkedIn)
  • Company industry classification
  • Company founding year
  • Technology stack (from job postings, StackShare, BuiltWith)
  • Social profiles (LinkedIn URL, Twitter handle)
  • Company description (from meta tags or About page)

Deep Enrichment

  • Recent funding rounds (amount, investors, date)
  • Recent news mentions (last 90 days)
  • Key competitors
  • Estimated revenue range
  • Recent job postings (growth signals)
  • Company blog/content activity (engagement level)
  • Executive team changes

Enrichment Depth Escalation Strategy

Not all leads deserve the same enrichment investment. Use a two-pass approach:

  1. First pass (Standard depth): Enrich all discovered leads at Standard depth. This is cost-effective and provides enough data for initial scoring.
  2. Score checkpoint: After the first pass, score all leads. Any lead scoring 70+ at Standard depth is a strong candidate.
  3. Second pass (Deep depth): Re-enrich only leads scoring 70+ at Deep depth. This focuses expensive research (funding history, news, competitive analysis) on leads most likely to convert.
  4. Skip threshold: Leads scoring below 30 after Standard enrichment should not be enriched further — the data is unlikely to improve their score enough to matter.

This approach typically reduces total enrichment cost by 40-60% while maintaining the same output quality for top-tier leads.

Email Pattern Discovery

Common corporate email formats (try in order):

  1. firstname@company.com (most common for small companies)
  2. firstname.lastname@company.com (most common for larger companies)
  3. first_initial+lastname@company.com (e.g., jsmith@)
  4. firstname+last_initial@company.com (e.g., johns@)

Note: NEVER send unsolicited emails. Email patterns are for reference only.

Lead Qualification Frameworks

BANT Framework

Use BANT to quickly qualify leads during or after enrichment. Each dimension maps to data you can discover through web research.

| Dimension | Question | Research Signals | |-----------|----------|-----------------| | Budget | Can they afford the solution? | Funding rounds, revenue estimates, job postings for related roles, pricing tier of current tools | | Authority | Is this person a decision-maker? | Title seniority (VP+, C-level, Director), reports to CEO/CTO, listed on "Leadership" page | | Need | Do they have the problem you solve? | Job postings mentioning the pain point, tech stack gaps, competitor tool usage, complaints on forums | | Timeline | Is there urgency to buy? | Contract renewals, compliance deadlines, product launches, recent leadership changes |

BANT Scoring Overlay

Apply these modifiers on top of the base lead score:

Budget confirmed (funding, revenue signal):   +5
Authority confirmed (VP+ or C-level):         +5
Need confirmed (pain point evidence):         +5
Timeline confirmed (urgency signal):          +5
                                     Max bonus: +20

MEDDIC Framework

Use MEDDIC for complex / enterprise sales qualification where longer deal cycles demand deeper research.

| Dimension | Definition | What to Look For | |-----------|-----------|-----------------| | Metrics | Quantifiable outcomes the buyer cares about | Case studies they publish, KPIs in job postings, analyst reports, earnings calls | | Economic Buyer | Person with budget authority to sign | CFO, CEO, VP Finance, or "Head of Procurement" listed on team pages | | Decision Criteria | Factors they use to evaluate vendors | RFP documents, vendor comparison blog posts, compliance requirements, review site feedback | | Decision Process | Steps from evaluation to purchase | Procurement team presence, legal/compliance review cycles, pilot program mentions | | Identify Pain | Specific problems driving the purchase | Support forums, Glassdoor reviews, social media complaints, analyst reports on industry challenges | | Champion | Internal advocate for your solution | Conference speakers, blog authors, open-source contributors, people who engage with your content |

MEDDIC Research Checklist
For each enterprise lead, attempt to discover:
[ ] At least one quantifiable metric they care about
[ ] The economic buyer's name and title
[ ] 2+ decision criteria (compliance, performance, price, integration)
[ ] Whether they run formal procurement (RFP, committee)
[ ] 1+ specific pain point with evidence
[ ] A potential internal champion (engaged user, tech advocate)

Choosing Between BANT and MEDDIC

The qualification_framework setting controls which framework is applied. When set to "auto", use this decision table:

| Scenario | Recommended Framework | |----------|----------------------| | SMB / startup targets, short sales cycle | BANT | | Enterprise targets, $100K+ deal size | MEDDIC | | Mixed list with varied company sizes | BANT first pass, MEDDIC for A-grade enterprise leads | | Time-constrained research | BANT (faster to assess) |


Deduplication Strategies

Matching Algorithm

  1. Exact match: Normalize company name (lowercase, strip Inc/LLC/Ltd) + person name
  2. Fuzzy match: Levenshtein distance 90 days without activity) for review
  • Provide clear data export in all supported formats

Common Pitfalls

1. Outdated Data

Problem: Company details change fast — people change jobs, startups pivot, funding info ages. Mitigation:

  • Verify every lead against at least 2 sources, and prefer sources updated within the last 90 days
  • Flag any data point older than 6 months as "needs re-verification"
  • Check LinkedIn tenure: if a contact joined their current role 10% headcount): -10

Lawsuit / regulatory action: -5 Executive turnover (CEO/CTO left): -5 Declining web traffic (per SimilarWeb): -3


### 8. Skipping the ICP Step
**Problem**: Jumping straight into search without a clear ICP produces scattered, low-quality results.
**Mitigation**:
- Always define the ICP **before** the first search query, even if it takes 5 extra minutes
- Write the ICP down explicitly (industry, size, geography, role, pain point, budget signal)
- Revisit and tighten the ICP after the first 10 leads if results are too broad

### Pitfall Severity Quick Reference
| Pitfall | Severity | Frequency | Fix Effort |
|---------|----------|-----------|------------|
| Outdated data | High | Very common | Medium (multi-source verification) |
| Single source reliance | High | Common | Low (add 1-2 extra sources) |
| Poor enrichment quality | Medium | Common | Medium (set thresholds, second pass) |
| Vanity list sizes | Medium | Common | Low (enforce scoring cut-off) |
| Company name variants | Medium | Very common | Low (normalize + domain match) |
| Hiring != purchase intent | Low | Occasional | Low (adjust scoring weight) |
| Ignoring negative signals | High | Common | Medium (add negative modifiers) |
| Skipping ICP | High | Occasional | Low (5-minute discipline) |
