About Stamba
A smart loyalty & customer-engagement platform connecting users with their favourite stores, restaurants and cafés through interactive digital stamps, gifts and personalised offers.
Stamba replaces the dog-eared paper loyalty card with a single, beautifully interactive wallet. Every coffee, every visit, every purchase earns a digital stamp — and once the card is full, the reward redeems in seconds.
Behind the simple "buy 10, get one free" idea sits a serious engine — behavioural analytics, location-aware offers and a merchant cockpit that lets shop owners design their own programs without writing a line of code.
For users, it's a wallet of cards from the brands they already love. For merchants, it's a complete CRM that learns who's coming back, who's drifting, and what offer will bring them in tomorrow.
Stamps in pockets, points on receipts, offers in DMs — loyalty was scattered. Stamba needed one wallet to hold it all.
One wallet, many merchants
Each café and shop ran its own paper card. Users carried five, lost three. We had to design a single home for hundreds of programs without flattening anyone's brand.
Trust the stamp, not the staff
Digital stamps are only valuable when they can't be cheated. We needed a redemption flow that worked offline, scaled across thousands of locations, and felt as quick as a paper punch.
Bilingual from day one
Arabic-first audience, English-second. Every screen had to flip RTL ↔ LTR without breaking; every font pair had to feel like the same brand in both scripts.
Our process
Six phases, one shared roadmap, weekly demos to the founder. We treated Stamba like a product, not a project — every sprint shipped something the team could tap, drag, or share.
Discovery & Research
Two weeks of user interviews with café owners, cashiers and stamp-card carriers in Riyadh and Jeddah. Mapped 17 competitor flows. Built a friction list: what makes someone abandon a loyalty card in the first 7 days.
Strategy & Architecture
Defined the wallet metaphor, the stamp grammar (8/10, 12/12, free reward), and the merchant data model. Decided early: every reward must redeem in under 4 seconds, online or offline.
UX Design & Prototype
Three rounds of wireframes, two rounds of clickable prototype testing with 22 users. Stripped the wallet from 7 tabs to 4. Killed the "search bar" — replaced with a horizontal stack of nearby merchants.
Visual & Brand System
Designed the Stamba S-mark, the red palette, and a card grammar that lets every merchant theme their stamp without breaking the wallet's rhythm. Built a 220-component library in Figma, RTL-ready.
Engineering & Build
Native iOS (Swift) and Android (Kotlin) shipped from a shared product spec. Node + Postgres for the wallet API; a React admin console for merchants. QR-based redemption with offline cache and signed receipts.
Launch & Iterate
Soft-launched with 8 merchants. Watched cohort metrics for 3 weeks, fixed the onboarding hand-off, then opened the gates. Now shipping bi-weekly with a backlog driven by merchant feedback.
How we helped Stamba ship
Four product surfaces, one design language. Every flow was prototyped in the wallet first, then translated to the merchant console — so the customer's promise and the merchant's tools never drift apart.
Interactive stamp cards that act like the brand they belong to.
Each card is a themed surface — burger joint, café, salon — designed so the merchant's identity reads instantly, while the stamp grammar stays universal. Pull-to-redeem, hold-to-validate, instant haptic confirmation.
An offer feed timed to when someone is most likely to walk in.
We trained a light-weight model on visit cadence and basket size to schedule the right notification at the right hour. Users opted in once — the inbox became a destination, not a nag.
A redemption flow that feels as quick as a paper punch.
Tap the reward, present the screen, cashier scans. A signed receipt is exchanged in under 1.4 seconds, online or offline. No staff training required — the success state is impossible to fake.
A nearby-stores layer that earns the home screen.
Cards, ratings, walking distance, and the next reward you're closest to — composed in a single scannable list. Adding a new merchant takes two taps, and stamps you've never collected appear with an irresistible "+".
A cockpit that turns visits into revenue.
Where the wallet ends, the console begins. A web dashboard built for owner-operators — so a café manager can read a cohort, design a campaign, and push it to thousands of phones without leaving the browser tab.
Live visit analytics
Average visits per customer, time between visits, and period-over-period change — owners spot drift before it becomes churn.
Demographics on tap
Age and gender splits that update as new members join. Build campaigns that actually fit the people walking through your door.
Member segments
Loyal customers, active members, and silent ones — separated automatically. Target each cohort with the right message at the right cadence.
Direct marketing
Push notifications, SMS blasts and in-app campaigns scheduled from one panel. Pick a segment, draft a message, see open rates in real time.
Visual card designer
Drag-and-drop a new stamp card — set the goal, the reward, the visual identity — and publish to every wallet that day. No tickets, no designers.
Multi-location
Switch between branches in a single click. Compare cards, campaigns and members across stores — or roll a promo out to every location at once.
Three surfaces, one product
Native on phones, browser on desktops, API everywhere in between. Built so a merchant can run a campaign from a laptop, then watch it land on a customer's lock screen ninety seconds later.
For Apple users
Native Swift app with widget support, Live Activities for active rewards, and Sign-in with Apple. Optimised for iPhone 12 → 15 Pro.
For Google users
Kotlin-first Android with Material You theming, push via FCM, and Wear OS companion. Tested across 18 device profiles from Galaxy A to Pixel 8.
For merchants
React-based web cockpit. Design a card, schedule a campaign, watch redemptions live, export the cohort to your CRM. Built for owner-operators who don't read manuals.
The wallet, screen by screen
A walk through the four screens that do most of the work — bilingual, RTL-ready, and tuned for one-handed thumb use.

The results
Six months after launch, here's what the dashboard says.
Repeat-visit rate across launch merchants vs. their paper-card baseline.
Active wallets in the first 6 months, growing 14% month over month.
Average rating across iOS & Google Play after the first 1,200 reviews.
Median tap-to-redeem time — 4× faster than the closest paper-card workflow.
Cafés, restaurants and retailers issuing Stamba cards across 6 cities.
Total stamps collected — equivalent to 2.1 million paper cards retired.
From app open to first stamp on file — tested across 30+ first-time users.
Sessions across iOS and Android, measured rolling-90-day post launch.
“HangingPanda didn't just deliver an app — they delivered a product. They pushed back on lazy decisions, prototyped what mattered, and shipped a wallet our customers actually open every day. The merchant console alone changed how we sell. Six months in and we're still on the same release train.
