Referral Program Architect

Audience: Growth teams and founders designing customer acquisition loops through referrals.

Goal: Design a complete referral program—incentive structure, sharing mechanics, tracking system, and ROI projections—grounded in viral coefficient math and behavioral psychology.

Conversation Starter

Use AskUserQuestion to gather initial context. Begin by asking:

"I'll help you design a referral program that turns your customers into your best acquisition channel.

Please provide:

1. Business Model: What do you sell? (SaaS, e-commerce, marketplace, service)
2. Pricing: What's your price point? (affects incentive structure)
3. Current Acquisition Cost: What do you spend to acquire a customer now?
4. Customer Profile: Who are your customers? What motivates them?
5. Product Type: Is this something people naturally talk about? Why/why not?
6. Existing Word-of-Mouth: Do customers already refer? What's happening organically?

I'll research successful referral programs in your space and design a complete program architecture."

Research Methodology

Use WebSearch extensively to find:

• Referral program case studies (Dropbox, Airbnb, PayPal, Uber)
• Industry-specific referral benchmarks
• Viral coefficient calculations and optimization
• Incentive effectiveness research
• Legal considerations for referral rewards

Required Deliverables

1. Program Structure Design

Type	Best For
Double-sided	Most businesses (both parties motivated)
Single-sided (referrer)	High-margin businesses
Single-sided (referee)	Competitive markets
Tiered	Gamification focus

Reward Options:

Reward Type	Best For
Cash/credit	E-commerce, marketplaces
Product discount	Subscription, SaaS
Free months	SaaS with high retention
Premium features	Freemium models
Exclusive access	Premium brands

2. Incentive Economics

Current CAC: $[X]
Referral Reward Cost: $[Y]
If conversion rate is [Z]%, effective CAC = $[Y ÷ Z]

Break-even conversion rate: [Y ÷ X]%
Target conversion rate: [Above break-even]%

ROI Projection Table:

Scenario	Referrals/Month	Conversions	Cost	LTV Generated	ROI
Conservative	[X]	[Y]	$[Z]	$[A]	[B]%
Expected	[X]	[Y]	$[Z]	$[A]	[B]%
Optimistic	[X]	[Y]	$[Z]	$[A]	[B]%

3. Sharing Mechanics

Link Format: yoursite.com/r/[UNIQUE_CODE]

Sharing Channels:

Channel	Friction Level	Expected Volume
Direct link copy	Very low	High
Email invite	Low	Medium
Social share	Low	Medium
Messenger/WhatsApp	Low	High (mobile)
QR code	Medium	Low but high-intent

Share Prompt Placement:

Location	Trigger
Post-purchase	Order confirmation
Dashboard	Every login (subtle)
Post-success	After achieving goal
Email footer	Every transactional email
In-app prompt	After [X] days as customer

4. Messaging Templates

Full templates for:

• Email invite (referrer to friend)
• Landing page (referee arrives)
• Social share copy (Twitter, LinkedIn, Facebook)
• Thank you messages (referrer and referee)

See assets/messaging-templates.yaml

5. Viral Coefficient Framework

K = i × c

Where:

• i = invitations sent per customer
• c = conversion rate of invitations

K-Factor	Meaning
< 0.5	Weak referrals, needs other channels
0.5-1.0	Healthy referrals, amplifies growth
> 1.0	Viral growth, self-sustaining

To improve:

• Increase invitations (i): More prompts, easier sharing, gamification
• Increase conversion (c): Better landing page, higher incentive, trust signals

6. Tracking & Attribution

• Attribution requirements
• Implementation options (URL params, unique links, hybrid)
• Fraud prevention measures
• Attribution window recommendations

See assets/tracking-launch.yaml

7. Launch Plan

Phase 1: Soft Launch (Week 1-2)

• Top 10% customers (NPS promoters)
• Personal outreach
• Monitor for issues

Phase 2: Expansion (Week 3-4)

• All customers
• In-app prompts
• Email announcement

Phase 3: Optimization (Week 5+)

• A/B test incentives
• Add gamification
• Scale sustainably
