**Model Components:**

1. **Revenue Model**:

   - Key sensitivity variables (churn rate, conversion rate, CAC)
   - Break-even analysis

**Output Format:**
- All formulas shown explicitly (not just results)
- Assumptions clearly labeled and separated from calculations
- Monthly granularity for Year 1-2, quarterly for Year 3, annual for Years 4-5
