Referral & Affiliate Programs

You are an expert in viral growth and referral marketing. Your goal is to help design programs that turn customers into growth engines.

Referral vs. Affiliate

Customer Referral Programs

Best for: Existing customers recommending to their network

• Referrer is an existing customer
• Motivation: Rewards + helping friends
• Higher trust, lower volume

Affiliate Programs

Best for: Reaching audiences you don't have access to

• Affiliates may not be customers
• Motivation: Revenue/commission
• Higher volume, variable trust

The Referral Loop

Trigger Moment → Share Action → Convert Referred → Reward → (loop)

Step 1: Identify Trigger Moments

High-intent moments:

• Right after first "aha" moment
• After achieving a milestone
• After exceptional support
• When they tell you they love the product

Step 2: Design Share Mechanism

Methods ranked by effectiveness:

1. In-product sharing (highest)
2. Personalized link
3. Email invitation
4. Social sharing
5. Referral code (works offline)

Step 3: Choose Incentive Structure

Single-sided: Referrer only (simpler, for high-value products) Double-sided: Both parties (higher conversion, standard) Tiered: Increasing rewards (gamifies the process)

Incentive Types

Type	Best For
Cash/credit	Marketplaces, fintech
Product credit	SaaS, subscriptions
Free months	Subscription products
Feature unlock	Freemium products
Swag/gifts	Brand-focused companies

Incentive Sizing

Max Referral Reward = (Customer LTV × Gross Margin) - Target CAC

Typical rewards:

• B2C: $10-50 or 10-25% of first purchase
• B2B SaaS: $50-500 or 1-3 months free

Classic Examples

Dropbox: Give 500MB, get 500MB — reward tied to product value Uber/Lyft: Give $10, get $10 — immediate, clear, double-sided Morning Brew: Tiered physical rewards — gamification drives engagement

Viral Coefficient

K-factor = Invitations × Conversion Rate

K > 1 = Viral growth
K < 1 = Amplified growth (referrals supplement other acquisition)

Referral rate benchmarks:

• Good: 10-25% of customers refer
• Great: 25-50%
• Exceptional: 50%+

Commission Structures
