our call

Start with Gatsby — highest vibe code, weakest moat.

  • Unique referral link generation and attribution tracking
  • Tiered membership status based on annual spend
  • Customer-facing widget for viewing point balance and available rewards

what you lose

  • Bi-directional offline POS sync for physical retail stores
  • Enterprise SOC 2 compliance and financial liability reporting for unused points
  • Native receipt scanning and OCR processing for third-party retail purchases
  • Dedicated customer success management and legal compliance for international incentive programs
  • Built-in fraud detection algorithms for referral link manipulation and fake accounts

  • Omnichannel POS and enterprise ERP integration ecosystem
  • Enterprise security certification, SLA guarantees, and points liability audit trails
  • Multi-region and multi-currency compliance for global enterprise brands

Gatsby

The core job—listening to Instagram webhooks, grabbing emails from DMs, and updating Klaviyo/Shopify—is trivial backend code. However, navigating Meta's App Review process, staying compliant with Messenger policies, and managing rate limits during viral bursts make running custom infrastructure a chore.

  • Email and phone collection flows via automated Instagram direct messages
  • Shopify customer metafield enrichment with Instagram handles and follower counts
  • Klaviyo profile property syncing and metric event dispatching
