Startup Due Diligence Skill

Overview

Conduct legal due diligence on early-stage US startups (Seed/Series A). This skill supports:

• Investors: Identify risks before investing
• Founders: Prepare for diligence, fix issues proactively

Workflow

Step 1: Intake

Collect context before proceeding:

1. Perspective: Investor or Founder?
2. Stage: Pre-seed / Seed / Series A
3. Scope: Full DD or specific area (Corporate, Cap Table, IP, etc.)
4. Company basics: Name, State, Entity type, Industry

Step 2: Document Collection

Based on scope, request documents by category. See references/checklists/ for complete lists:

Category	Reference File
Corporate & Formation	references/checklists/corporate.md
Cap Table & Securities	references/checklists/cap-table.md
Intellectual Property	references/checklists/ip.md
Employment & Founders	references/checklists/employment.md
Material Contracts	references/checklists/contracts.md
Compliance & Regulatory	references/checklists/compliance.md
Litigation	references/checklists/litigation.md
Financial	references/checklists/financials.md

Step 3: Document Review

For each document received:

1. Identify document type and category
2. Check against category-specific criteria
3. Flag issues using severity ratings (see below)
4. Cross-reference with other documents for consistency

Severity Ratings:

• 🔴 CRITICAL: Deal blocker, must resolve before closing
• 🟠 MATERIAL: Significant risk, requires remediation plan
• 🟡 MINOR: Should be fixed, but not blocking

See references/red-flags/common-issues.md for comprehensive issue patterns.

Step 4: Issue Analysis

For identified issues, provide:

1. Description: What the issue is
2. Risk: Why it matters
3. Remediation: How to fix it
4. Timeline: Estimated effort to resolve
5. Escalation: Whether legal counsel required

Step 5: Report Generation

Generate deliverables using templates in assets/templates/.

CRITICAL: Template Usage Protocol

NEVER directly edit template .docx files. Always use the deterministic script:

# 1. Collect data into JSON
cat > data.json << 'EOF'
{
  "COMPANY_NAME": "Acme Inc.",
  "REPORT_DATE": "2024-01-15",
  ...
}
EOF

# 2. Validate data
python scripts/validate_data.py diligence-report data.json

# 3. Populate template (deterministic - only fills {{PLACEHOLDERS}})
python scripts/populate_template.py assets/templates/diligence-report.docx data.json output.docx

This ensures template text is NEVER modified - only placeholders are filled.

Guidance Documents

Load these as needed based on the issues encountered:
