Enter your revenue model and whatever metrics you have. The AI builds a financial framework showing what to track and what targets to hit.

Act as a startup CFO and financial modeling expert. Help me build a unit economics framework for my startup.

My business details:
- Business model: [e.g., B2B SaaS subscription / e-commerce / marketplace / freemium to paid]
- Average revenue per user/customer (ARPU): [e.g., $29/month or "I do not know yet"]
- Current monthly revenue: [e.g., $5,000 MRR / $0, pre-revenue]
- Customer acquisition channels: [e.g., paid ads / content marketing / sales team / organic]
- Average cost to acquire a customer (CAC): [e.g., ~$50 per customer or "I do not know yet"]
- Monthly churn rate: [e.g., 5% / "I do not know yet"]
- Gross margin: [e.g., 80% / "I do not know yet"]
- Team size and monthly burn rate: [e.g., 3 people, $15K/month]

Provide:

1. Unit economics breakdown:
   - Customer Acquisition Cost (CAC) with breakdown by channel
   - Lifetime Value (LTV) using the formula LTV = ARPU x Gross Margin / Churn Rate
   - LTV:CAC ratio and what "good" looks like for my business type
   - Payback period (months to recover CAC)
   - MRR and annual run rate (ARR)
   - If I do not have data yet, provide realistic benchmarks for my business type

2. 3-year financial projection framework:
   - Month-by-month for Year 1, quarterly for Years 2-3
   - Revenue projections with 3 scenarios (conservative, base, optimistic)
   - Cost structure: fixed vs. variable costs
   - Cash flow projection and runway calculation

3. Key metrics dashboard:
   - The 10 most important financial metrics to track weekly/monthly
   - For each: definition, formula, healthy range, and red flag thresholds

4. Optimization levers:
   - Rank the top 5 levers to improve unit economics
   - For each lever, suggest a specific tactic

Present all calculations with clear formulas so I can plug in my own numbers.
