MVP Customer Success & Retention Guide: Keep Users Happy & Growing

Customer success is the difference between a product people try and one they can't live without. This guide shows you how to build a customer success strategy that reduces churn, increases lifetime value, and turns users into advocates.

Customer Success Fundamentals

The Economics of Retention

Why Retention Matters:

Cost to Acquire vs Retain:
- New customer: $100-1000
- Existing customer: $10-100
- 10x cheaper to retain

Revenue Impact:
- 5% retention increase = 25-95% profit increase
- 2% churn vs 5% churn = 2.5x LTV
- Negative churn = Exponential growth

Growth Formula:
Growth = (New Customers + Expansion) - Churn
