Unit Economics & SaaS Pricing Tier Sensitivity Model

Act as a SaaS Monetization Strategist and Financial Modeler.

Analyze and optimize the pricing structure for:
- Product Description: [What the software does and who buys it]
- Current Pricing & Packaging: [e.g. $19/mo Starter, $49/mo Pro, Enterprise quote]
- Value Metric: [e.g. Per seat, per API call, per gigabyte, per active contact]
- Customer Feedback: [e.g. 'Too expensive for freelancers', 'Enterprise wants custom contracts']

Deliver:
1. Value Metric Audit: Evaluate if the current billing unit scales with customer success.
2. 3-Tier Packaging Architecture (Good / Better / Best):
   - Tier Name & Price Point
   - Target Customer Segment
   - Feature Gates & Psychological Anchoring
3. Expansion Revenue Mechanisms: Add-ons, usage overages, and seat expansion levers.
4. Financial Sensitivity Analysis: Model projected revenue impact under a 20% price increase against potential 5% churn.
5. Migration & Grandfathering Strategy: How to transition existing users without triggering backlash.
