The challenge

Cafés spend to get customers in the door once, then lose them — with no contact details, no follow-up, and no reason for that customer to return.

They needed a dead-simple way to capture opted-in customers and re-engage them automatically, with zero extra work for busy staff.

What we built

A single QR code at the table: the customer scans, instantly receives a welcome offer on WhatsApp, and is enrolled into automated journeys — birthday offers, re-engagement nudges when they haven't visited in a while, and reminders before an unused coupon expires.

Staff redeem coupons through a lightweight web form, so the whole loop runs without touching a POS system.
