# Claim Verification Methodology

When analyzing claims from pitch decks, founder statements, or company materials, follow this rigorous verification process.

## Verification Levels

Assign one of these confidence levels to every claim:

| Level | Definition | Requirements |
|-------|------------|--------------|
| **VERIFIED** | Confirmed via 2+ independent sources | Multiple credible sources agree |
| **PARTIALLY VERIFIED** | Some evidence supports, gaps remain | One credible source + logical consistency |
| **UNVERIFIED** | Cannot confirm with available data | No independent sources found |
| **CONTRADICTED** | Evidence conflicts with claim | Sources disagree with stated claim |

## Verification Process

### 1. Identify the Claim
Extract the specific, testable assertion:
- ❌ "We're growing fast" (vague)
- ✅ "We grew 300% YoY in 2024" (specific, testable)

### 2. Find Independent Sources
Never rely solely on company-provided materials. Seek:
- Public filings (SEC, state records)
- Third-party data providers (Crunchbase, PitchBook, LinkedIn)
- Press coverage (with dates)
- Customer reviews and testimonials
- Industry reports from analysts

### 3. Cross-Reference
Compare across sources:
- Do numbers align within reasonable variance (±10%)?
- Are timelines consistent?
- Do different sources tell the same story?

### 4. Document Everything
For each verified claim, record:
```json
{
  "claim": "The specific claim text",
  "confidence": "VERIFIED | PARTIALLY VERIFIED | UNVERIFIED | CONTRADICTED",
  "sources": [
    {"name": "Source name", "url": "URL if available", "date": "YYYY-MM-DD"}
  ],
  "notes": "Any caveats or context"
}
```

## Red Flags

Watch for these warning signs:
- Round numbers without context ("$10M ARR exactly")
- Claims that can't be independently verified
- Metrics that don't match industry standards
- Vague timeframes ("recently", "soon")
- Comparisons without clear methodology

## Output Format

Include a verification summary in your analysis:

```json
{
  "verification_summary": {
    "total_claims_analyzed": 15,
    "verified": 8,
    "partially_verified": 4,
    "unverified": 2,
    "contradicted": 1
  },
  "key_concerns": [
    "Market size claim contradicted by industry reports",
    "Founder employment dates don't match LinkedIn"
  ]
}
```
