Meta and Google build lookalikes from anyone who bought once — so a one-time discount shopper and your most devoted customer look identical to the algorithm. Affinity fixes that. It builds a private identity graph from your orders, site visits, email engagement, reviews, and support conversations, scores every customer 0–100 against your own store, and shows exactly why. Then it syncs your highest-affinity customers to Meta Custom Audiences and Klaviyo — hashed, consent-gated, and automatic.

• A 0–100 affinity score for every customer, ranked within your own store
• Six devotion signals: orders, recency, visits, email opens, reviews, support
• One-click sync of consented, hashed audiences to Meta Custom Audiences
• Affinity scores written back to Klaviyo for segments and flows
• Consent-first: honors Shopify Customer Privacy, full GDPR deletion built in
