How Roast & Co. Grew Their Return Visit Rate by 4.2× in 90 Days

The Background: 300 Customers a Day, Getting Nothing Back

Roast & Co. is a mid-range café in Kilimani, Nairobi. When James Kariuki opened in 2023, he invested heavily in the space — specialty coffee, a curated menu, and free WiFi as standard. By early 2026, he was consistently pulling 280–320 customers on a weekday.

James knew the café was performing well on foot traffic. What he didn't know was that he was essentially running a marketing department with no outputs. Every customer who connected to the WiFi and left was gone forever. No name, no email, no way to reach them again — even if they had a great experience and intended to come back.

"I remember doing the maths one afternoon," James told us. "We had maybe 300 people through the door that day. I could tell you our coffee-to-food sales ratio, our average basket size, our table turnover time. But I couldn't tell you a single customer's name. That felt insane."

The Problem: A Loyalty Gap With No Bridge

James had a rough idea of what his return customer rate was — he recognised faces, and a few regulars came in by name. But when Centipid's analytics first started tracking WiFi session data, the numbers were stark.

Only 16% of customers who connected in Month 1 connected again within 30 days. The rest — 84% — were effectively one-time visitors, even if they'd had a perfectly good experience.

This isn't unusual for food and beverage businesses. The Centipid platform data across all restaurant customers shows an average first-month return rate of 19% without any automation. The reasons are simple:

• Customers have dozens of alternatives and no particular reason to choose you over a competitor on their next outing
• There's no friction-free mechanism to remind them you exist
• The average African urban consumer has 4–7 regular dining venues they rotate between — you need a reason to be in that set

James had tried posting more on Instagram. He'd run two Nairobi Facebook ad campaigns. Both drove some new faces but did almost nothing to bring existing customers back. "It's backwards," he said. "I was spending money to reach strangers when I had 300 warm leads walking in every day."

The Setup: Live in Under 24 Hours

James signed up for Centipid's Starter plan ($50/month) on a Tuesday afternoon. He was hesitant about anything that required technical work — the café already ran on MikroTik hardware, and he'd had a difficult time with a previous supplier who took three weeks to configure a POS integration.

The setup experience was different. After signing up, the Centipid onboarding team sent James a short credentials form. By Wednesday morning, his MikroTik router was configured remotely, his branded captive portal was live, and customers were connecting and being captured in real time.

"The fastest part was the portal design," James told us. "I've spent longer choosing fonts for a menu reprint."

The 5 Campaigns That Changed Everything

James activated all five available automation flows on his Starter plan within his first week. Here's exactly what each one does, and the results each one drove at Roast & Co.

1. First-Visit Welcome Offer

When a customer connects to Roast & Co.'s WiFi for the first time, they receive an automated WhatsApp message within 5 minutes: "Welcome to Roast & Co.! Thanks for visiting. Show this message to your barista for a free upgrade on your next drink. Valid for 7 days."

This single automation runs silently in the background, every day, for every new customer. It costs James nothing beyond the monthly subscription. In the first 90 days, it was sent to 4,240 new customers. Redemption rate: 34%. That's 1,441 customers who came back for a second visit specifically because of the offer — and became part of Centipid's tracked customer base.

2. The 14-Day Win-Back Campaign

This is the automation James credits most for his Friday night turnaround. Any customer who connected at Roast & Co. and hasn't reconnected in 14 days receives a personalised message: "Hey [name], we've missed you at Roast & Co.! It's been a while — come back this week and your second coffee is on us."

The timing is deliberate. At 14 days, the customer still has a fresh memory of the café but has clearly not prioritised returning. The message arrives as a push — not an email that gets buried — and includes a sense of personalised acknowledgement that's rare from a casual dining venue.

In 90 days, Centipid sent 2,840 win-back messages on James's behalf. Open rate: 91%. Re-visit rate: 44%. That's 1,250 customers who returned specifically because of an automated message that took James zero effort to send.

3. Birthday Campaign

The Centipid captive portal asks for an optional birthday when customers register. About 58% of Roast & Co. customers filled it in. Every customer who provided a birthday automatically receives a message on their birthday week: "Happy Birthday from all of us at Roast & Co.! Your free slice of cake is waiting — come celebrate with us this week."

This automation builds over time. In the first 90 days its direct revenue impact was modest (only a small percentage of the customer base had birthdays in that window). But it's compounding — James now has birthday data for over 3,200 customers, and it runs forever without any intervention.

4. Google Review Request

Thirty minutes after a WiFi session ends — when the customer has left the café and the experience is still fresh but they're not in a hurry — Centipid automatically sends a Google Review request. Customers who rate 4–5 stars are directed to the Google Business profile. Those who select 1–3 stars receive an internal alert to the café email instead.

James had 40 Google reviews before Centipid. He now has 290. His average rating went from 4.1 to 4.7 stars. "The smart routing was the thing I didn't expect," he said. "I used to dread bad reviews appearing publicly. Now I see them before they go live and I can call the customer."

5. Weekend Flash Sale

Every Friday at 2pm, Centipid sends a WhatsApp message to all customers who visited Roast & Co. in the last 30 days: "Weekend special: half-price pastries with any hot drink — Saturday and Sunday only. See you this weekend!"

This is the automation that changed the weekend dynamic at the café. In Month 1, it reached 847 customers. By Month 3, the Friday blast was hitting 5,200 customers every week. The café now turns away walk-ins on Friday evenings — something that had never happened before.

The Results: 90 Days by the Numbers

At the start of January 2026, Roast & Co.'s return visit rate — the percentage of first-time customers who returned within 30 days — was 16%. By the end of March 2026, 90 days after going live with Centipid, it was 68%. That's a 4.2× increase.

James's Centipid dashboard showed a customer acquisition cost from existing visitors (the cost per return visit generated through campaigns) of approximately KES 14 — roughly $0.11 per reactivated customer. His average transaction value is KES 850. "There's no marketing in the world with that ROI," he said.

Perhaps most significantly, Roast & Co. now has something it didn't have before: a direct, owned marketing channel to 8,240 customers. Even if James never runs another Instagram ad, he can reach his entire customer base at any time — for free.

Key Takeaways for Other F&B Operators

The Roast & Co. story isn't unusual. Across Centipid's restaurant and café customer base, the pattern is consistent: the operators who see the biggest results are those who activate multiple campaign types from day one and let them run.

A few lessons that apply broadly:

• Don't underestimate your existing foot traffic. Most cafés and restaurants are already at the hard part — getting customers through the door. Converting a fraction of those into return visits is dramatically cheaper than acquiring new ones.
• Timing is everything for review requests. Sending a review request in-venue or immediately at departure has lower response rates than sending it 20–40 minutes post-session. Customers are less distracted, still in a positive frame, but not in a hurry.
• Win-back messages work because they feel personal. The message "we've missed you" reads differently from a brand blast because it acknowledges a prior relationship. Even customers who know it's automated respond to the implied familiarity.
• The value compounds. The customer database James built in 90 days is an asset he owns permanently. Every new customer added to that list is one more person he can reach for the cost of an SMS.
