What problem does it solve? Building a referral or affiliate program from scratch involves hard decisions about incentive sizing, commission structures, fraud prevention, and tooling. This Skill provides a structured framework for designing, launching, and optimizing word-of-mouth growth programs grounded in LTV and CAC economics. ## Core Features & Use Cases - Program Design: Choose between customer referral, affiliate, or hybrid models, and structure single-sided, double-sided, or tiered incentives sized against customer LTV and target CAC. - Growth Modeling: Calculate viral coefficient (K-factor), referral rate benchmarks, and program ROI to forecast whether referrals can drive meaningful acquisition. - Launch & Optimization: Get launch checklists, email sequences, A/B test ideas, fraud prevention measures, and tool comparisons (ReferralCandy, PartnerStack, Rewardful, and more). - Use Case: A SaaS founder wants to turn happy customers into an acquisition channel. The Skill walks them through trigger moments, reward sizing (e.g., $50 credit per referral given a $1,200 LTV), tracking setup, and a 30-day post-launch optimization plan. ## Quick Start Help me design a double-sided referral program for my B2B SaaS product with a $1,200 customer LTV and $200 target CAC.
