What problem does it solve? It guides the design, launch, and optimization of referral and affiliate programs so businesses can turn existing customers and partners into a measurable acquisition channel instead of relying on ad-hoc word of mouth. ## Core Features & Use Cases - Program Design: Distinguishes referral vs. affiliate programs and builds the full referral loop (trigger moment, share mechanism, conversion flow, reward structure) with single-sided, double-sided, and tiered incentive options. - Optimization & Measurement: Diagnoses low participation or conversion, provides A/B test ideas, fraud prevention tactics, and defines key metrics like viral coefficient, referral rate, and referral CAC vs. LTV. - Use Case: A $49/month SaaS with 1,000 customers wants word-of-mouth growth. The skill recommends a double-sided incentive (free month for both parties), in-product sharing prompts at satisfaction moments, a launch checklist, and tools like Rewardful or Tolt. ## Quick Start Ask the assistant to design a referral program for your product, including incentive structure, launch checklist, and recommended tools.
