Turn Amazon purchase behaviour into Meta & TikTok audiences.
Not lookalikes — actual buyers who are due to reorder.
Social ad targeting is mostly guesswork: interests, broad audiences, lookalikes. But you already know exactly who bought what, and when. We turn your Amazon (and DTC) purchase and reorder behaviour into hashed, privacy-safe audiences you push straight to Meta and TikTok — refreshed weekly.
The setup
A lookalike models strangers off your customers. Why target a proxy when you can target the real thing — the customer whose 60-day supply runs out next week, with the ad landing right as they go looking?
What it does
→Per-EAN reorder windows — we learn each product's real reorder cycle, per customer, not a category guess.
→Predicted-reorder lists — the customers entering their reorder window now, across Amazon and Shopify, excluding Subscribe & Save so you don't pay to reach auto-renewers.
→Hashed export — privacy-safe and ready to drop into Meta / TikTok custom audiences, regenerated every week as buyers move through their cycle.
Why it beats lookalikes
Reach the buyer in the days before they reorder
A lookalike is a guess about who might resemble a customer. A reorder-window audience is the customer themselves, surfaced in the short window when intent is highest — the week their last pack runs out.
How it surfaces: your own purchase history, reshaped from a record into a target — the data already exists; it just isn't built for activation.
What it changes
→Win the reorder before a competitor's ad gets in front of your customer first.
→Stop wasting spend on Subscribe & Save customers who are going to repeat anyway.
→Better lookalikes too — seed Meta / TikTok with your actual repeat buyers, not just anyone who clicked once.
How we see it
Built on your own purchase data, resolved across Amazon and DTC, and hashed before it ever leaves — compliant by construction. The reorder model runs weekly, so the audience you push is always the cohort that's actually in-market this week. Live today on a real multi-channel brand.
Runs on the same cross-channel identity layer as the crossover (03) and LTV bidding (05).
The takeaway
Why this matters
The single most valuable targeting signal you own — who is about to run out — is locked inside your sales history, in the wrong shape to use. We reshape it into an audience. A third eye that turns records into reach.
