How Burger King Collected 29K Emails and Added $85K in Sales, All With $0 Ad Spend

Restaurant growth isn’t just about serving great food — it’s about turning every visit into a measurable opportunity.

In this case study, Burger King Costa Rica flipped the script on traditional loyalty and acquisition tactics by building a data-driven retention engine with zero ad spend. By capturing first-party guest data through QR codes and automating personalized follow-ups, the brand collected 29,000+ emails in just 90 days and generated $85,000 in tracked revenue — proving that restaurants can unlock sustainable growth not with guesswork, but with systems that turn anonymous guests into repeat customers and lasting value.

From Anonymous Foot Traffic to Trackable Revenue

Burger King Costa Rica already had the brand, the stores, and the traffic.

What they wanted was a smarter way to track and activate in-store visits — turning everyday guest interactions into measurable, long-term revenue.

Initial goal: “Grow our customer database and promote our app.”

Actual outcome: A permanent, automated growth engine fueling revenue, retention, and LTV — with no media spend.

Inside Dishio’s Engine for Data + Revenue

We deployed Dishio’s Capture & Automate framework inside their restaurants:

  • Strategic QR Placement — windows, tables, cashier counters.
  • Instant Data Capture — emails, pixel IDs, and behavioral tags collected in seconds.
  • Dynamic Offer Delivery — personalized via email + mobile microsite.
  • Behavior-Driven Flows — redeemers, non-redeemers, and first-timers each received tailored follow-ups.
  • Audience Infrastructure — built for future app pushes, seasonal offers, and loyalty programs.

The Results — All Organic

  • 29,000 new guest emails collected in 90 days
  • $85,000 in tracked direct sales — with $0 spent on ads
  • 5,000 app downloads driven through personalized offers
  • 25%+ redemption rate on targeted promotions
  • Pixel-ready audiences built for Google, Meta, and TikTok

The Data Most Brands Let Walk Out the Door (Approx. 6-Month Potential)

At this pace, Burger King Costa Rica would collect about 62,000 customer contacts in six months — valuable first-party data they can use for campaigns, retargeting, and loyalty programs.

Why the System Keeps Paying Off

This wasn’t a one-off coupon promo. It was a repeatable, tech-driven revenue system:

  • First-Party Data Ownership — every scan created a reusable, monetizable contact.
  • Behavioral Segmentation — contacts tagged for precise targeting later.
  • Automated Re-Engagement — sequences running without extra labor.
  • Future-Proof Growth — a database ready for any campaign, any time.

Next: Driving App Downloads With the Same Engine

With a 40k+ owned audience and behavioral tags in place, Burger King is launching an App Download Growth Push,  using Dishio-powered email and paid social to maximize ROI.

The Case for Capturing Every Customer, Every Time

Strong brands with heavy foot traffic can still leave growth on the table.

Burger King Costa Rica turned visits into a long-term revenue source, without spending a cent on ads.

Dishio can do the same for any restaurant ready to:

  • Capture and own guest data.
  • Automate re-engagement.
  • Grow LTV without paying for every impression.

Frecuently Asked Questions

This FAQ is your quick guide to how Dishio helps restaurants turn guest data into repeat revenue. Whether you’re new to Dishio or exploring better ways to keep guests coming back, you’ll find clear answers here.

No. Dishio does not replace your POS. It works alongside your existing POS by capturing guest data and behavior outside the transaction—when guests scan menus, visit your site, or engage digitally—so you can track, retarget, and re-engage them after the visit. 

Dishio captures first-party guest data when guests interact with your digital touchpoints, such as QR menus, smart websites, event RSVPs, or forms. This includes contact details and behavior signals that are automatically stored and used for follow-ups, segmentation, and retargeting.

Yes. While QR codes are a powerful entry point, Dishio can also capture guest data through websites, landing pages, forms, and digital campaigns. QR codes simply make in-store data capture frictionless—but they are not required.

Dishio turns one-time visits into ongoing relationships by automating personalized follow-ups based on guest behavior. Instead of relying on punch cards or generic blasts, Dishio helps restaurants re-engage guests with relevant messages, offers, and experiences that drive return visits and higher lifetime value.
