Referral Program (Global)
Word of mouth is the highest-LTV acquisition channel in every region. But the LEGAL framework around how you contact referred prospects differs HUGELY: TCPA (US, SMS), GDPR (EU, all channels), PDPA (SEA), LGPD (LATAM). Pick the right region variant or get fined.
For newbies
Who is this skill for?
Audience
Concrete example
DTC brand wanting cheaper acquisition
Already at USD 30 CAC; want USD 10 CAC via referral
B2B enterprise sales -> ABM / partnership programs are different motion (not covered here)
Brand ambassador / affiliate -> Use 27-personal-brand-monetize-global for influencer-affiliate (when available)
30-second pre-read
This skill produces ONE referral program design with 6 components: model selection (1-way / 2-way / multi-tier), incentive math (% of LTV), tracking infrastructure, anti-fraud measures, launch sequence, and KPIs (K-factor, viral coefficient). Pick 1 of 4 region variants — the variant tunes the LEGAL rules for contacting referred prospects (especially via SMS/email).
3 common errors
SMS-based referral in US without TCPA consent -> Up to USD 1,500 per text fines + class actions
Email-blast referred contacts in EU -> GDPR violation; referral programs touching EU prospects need explicit consent from the prospect, NOT just the referrer
Cash incentives that violate FTC endorsement rules -> "Refer a friend, get USD 100" requires disclosed material connection if referrer posts publicly
Why do you need this skill?
Without proper referral design:
US: Risk TCPA class action (USD 500-1,500 per message)
