QR Contact Card Generator - Iteration 4: Data-Driven Growth Engine

Executive Summary​

Business Model Evolution: Free QR generator → Data exchange platform → Multi-product ecosystem

Core Value Exchange:

  • Users get: Free QR generator + enhanced features for more engagement
  • Coditect gets: Marketing consent + contact graph data + cross-promotion channel

Expected Impact:

  • K-factor: 3.0 → 4.5+ (data network effects)
  • CAC: $0.50 → $0.20 (contact list monetization offsets)
  • LTV: $120 → $450 (multi-product revenue)
  • Opt-out rate: <5% (industry standard: 15-25%)

Risk & Compliance​

Privacy Concerns​

Mitigation:

  • Explicit opt-in (not opt-out default)
  • Granular consent controls
  • Right to be forgotten (GDPR Article 17)
  • Data export on demand
  • Annual consent refresh

Spam Perception​

Mitigation:

  • User-controlled email frequency
  • Immediate unsubscribe (one-click)
  • Content quality > quantity
  • Segmented, relevant messaging

Value Imbalance​

Mitigation:

  • Transparent value exchange
  • Tangible benefits (credits, unlocks)
  • Progressive disclosure (no surprises)
  • Regular value audits (survey users)
