How Café Bloom Increased Revenue by 30% in 3 Weeks

Café Bloom is a 40-seat coffee shop in the 11th arrondissement of Paris. Owner Marie Duval had the same problem every small café faces: regulars loved the place, but there was no system to keep them coming back consistently.

“We had a paper punch card,” Marie says. “Buy 9 coffees, get the 10th free. Maybe 10% of people actually completed one.”

The problem

Café Bloom's revenue was flat. Weekday mornings were strong, but afternoons and weekends were hit-or-miss. Marie tried Instagram promotions and a $500 Google Ads campaign. Both brought in new faces, but most never came back for a second visit.

The real issue wasn't attracting customers — it was keeping them. Marie had no way to contact people who'd visited once, no data on who her regulars were, and no tool to bring people back.

The solution

In February 2025, Marie launched a digital loyalty card with Kyro. Setup took one afternoon. Here's what she did:

• Card type: Digital punch card (buy 9, get 1 free) — same as before, but in Apple Wallet
• Sign-up: QR code at the counter + a small table tent card
• Incentive: First stamp given free for signing up

Week 1: 127 sign-ups

Marie was surprised by the adoption rate. “People pulled out their phones and added the card in 10 seconds. No app to download, no account to create. That was the key.”

By end of week 1, 127 customers had added the digital card. Marie now had 127 names, emails, and phone numbers — a customer database she'd never had in 4 years of running the café.

Week 2: The notification experiment

Marie sent her first push notification on a slow Wednesday afternoon: “Double stamps today until 5pm” The result: 34 visits that afternoon, compared to the usual 12.

“I couldn't believe it,” she says. “These were people who'd already been in that week. They came back for a second visit because their phone reminded them.”

Cost of that notification? $0. The equivalent SMS campaign would have cost $12-15.

Week 3: The numbers

By the end of week 3, the results were clear:

• Revenue: +30% compared to the same 3 weeks last year
• Repeat visits: +45% (customers visiting 2+ times per week)
• Card completion rate: 38% (vs. ~10% with paper)
• Customer database: 312 contacts (from zero)
• Notification open rate: 67%

What made it work

Zero friction sign-up

No app download. No account creation. Scan QR → add to wallet → done. This is why 127 people signed up in week 1. If it had required an app, Marie estimates she'd have gotten maybe 15.

The notification channel

Being able to reach customers directly through their lock screen — for free — changed everything. Marie now sends 2-3 notifications per week: slow day promotions, new menu items, and “you're X stamps away from a free coffee.”

Data-driven decisions

For the first time, Marie could see patterns. She learned that her best customers visit on Tuesday and Thursday mornings, that 60% of redemptions happen on Fridays, and that customers who get their 3rd stamp within 2 weeks almost always complete the card.

Marie's advice

“Don't overthink it. Put the QR code at the counter, give them a free stamp for signing up, and let the system do the rest. The notifications bring people back. That's the whole game.”

The takeaway

Café Bloom didn't change their coffee, their menu, or their prices. They just gave customers a reason to come back — and a system to remind them. The result: 30% more revenue in 3 weeks, a growing customer database, and a marketing channel that costs nothing to use.
