Retain more. Earn more. Do less.

Branded loyalty cards, a live customer dashboard and an add-on AI agent that works in the background through WhatsApp messages.

Know your customers. Grow repeat business.

See every customer's name, visits, spend and last visit in one live dashboard. Spot top spenders, identify lapsed customers early, and act before revenue slips away.

Reward customers your way

Choose from points, stamps, cashback, gift cards, memberships, coupons, prepaid balances and discounts. Every reward is fully branded to your business and tracked automatically at each visit.

Bring back lapsed customers automatically

Trigger push, SMS or WhatsApp campaigns when someone hasn't visited for 30 days. Set it up once from a single screen and let the system handle the follow-up.

Automations that run for days, not seconds

Build multi-step sequences once: a reminder today, an offer in three days and a follow-up next week. Campaigns keep running in the background while you run the business.

Turn regulars into paying members

Create subscription cards and bill memberships through Stripe, with charges collected automatically each month. Predictable recurring revenue without chasing payments.

Go hands-off with Flann + MSTRMND

Combine MSTRMND with Flann AI and campaigns write, personalise and send themselves. You choose the goal; Flann handles targeting, messaging and delivery.

Pick the system that fits your business.

The businesses that installed MSTRMND and never looked back.

The subscription was what got me interested. 40 members in the first six weeks. The regulars loved it. But honestly the stamp card caught me off guard too. Works better than I expected.

Darren Mills

Fade & Co Barbershop · London

My customers used to forget their stamp card constantly. Now it's on their phone. That's basically it. They come back more.

Fiona MacAllister

The Wee Coffee House · Edinburgh

I didn't know how many clients weren't coming back until I could actually see it. That was a bit of a wake up call if I'm honest. It's better now.

Maja Kowalczyk

Atelier Piękna · Kraków

Furniture isn't something people buy every month so I wasn't sure this made sense for us. But I had a customer come back for a second purchase and she said the message reminded her. That was enough for me.

Khalid Bensalem

Dar Al Raqi Furniture · Tripoli

Nothing frustrated me more than losing clients between appointments and not knowing why. This just keeps me in front of them without me having to do much. Retention is better. I stopped discounting.

Priya Nair

Lumière Aesthetics Clinic · Toronto

People forget you exist between cleans. I use it to stay on their radar. Getting more repeat bookings and a few referrals too which I wasn't expecting.

No. A punch-card app gives a customer a card and stops there. MSTRMND tracks every visit and spend in a live database, rewards customers automatically, and lets you reach the ones who go quiet by push and SMS, or full WhatsApp campaigns once you add Flann. The card is the start. The system is what brings them back.

Never. The loyalty card lives in Apple Wallet or Google Wallet. Customers scan one QR code and add it in under 30 seconds. Nothing to download, nothing to log into.

Flann is your optional AI agent. Once your loyalty system is live, Flann can analyse visit and spend patterns, draft campaigns in your brand voice, and queue them for delivery. You approve with one reply on WhatsApp. The platform runs perfectly without it; Flann just makes it hands-off.

When a customer comes within 100 metres of your location, they get a gentle push on their phone: a nudge to come in, redeem points, or check an offer. (iOS.)

Yes. Upgrade any time; downgrade at your next billing cycle.

You start with a 14-day free trial, full done-for-you setup included, and you're not charged until it ends. If it's not right for you, cancel anytime before day 14 and you won't pay a penny. No forms, no fuss.
