Referral Program Building

Build viral referral programs that drive 2-3x higher conversion rates with 37% better retention.

Quick Start

1. Define Program Type - Choose reward structure matching business model
2. Select Platform - Pick tool based on scale and integration needs
3. Implement Tracking - Set up attribution, fraud prevention, analytics
4. Launch & Optimize - Soft launch, measure KPIs, iterate

Core Principles

• Two-Sided Rewards: Both referrer AND referee get incentives (68% higher participation)
• Product Alignment: Use product as reward when possible (Dropbox model)
• Integration: Embed in user workflow, not separate feature
• Simplicity: Explain in 2-3 bullet points or it's too complex
