Nectar — a loyalty app for a grocery chain

2024

A loyalty platform for NetCost Market that replaced paper punch cards: a digital card that works at any checkout, four reward tiers, weekly challenges and referrals, synced in real time with the Maestra loyalty engine.

01Challenge

Paper punch cards gave the chain zero insight into its customers.

NetCost Market needed a loyalty program its customers would actually use — not another plastic card in a drawer. It had to run on Maestra, work at the checkout even offline, send promotions and scale across every store.

02Solution

Every customer’s phone became a loyalty card.

We built Nectar as a native iOS and Android app plus a PWA. A secure Express proxy keeps Maestra keys server-side, points update in real time, and tiers, challenges and referrals give people a reason to come back.
