How sunday Became a Restaurant Fintech Star by Killing the Paper Check
sunday is a restaurant fintech that grew fast by killing the paper check. Fintech means financial technology, or tools that make money tasks easier. A “check” here is the printed bill a waiter brings at the end of a meal. sunday replaced that slip of paper with a simple QR code. A QR code is a square barcode you scan with your phone. Scan it, and the bill opens on your screen. You pay in seconds, leave a tip, and walk out. No waiting, no paper, no fuss.
This simple idea solved a real pain. Diners often wait a long time just to pay. That slow moment costs restaurants money and goodwill. sunday made paying quick and easy. The company grew into one of the fastest-rising names in restaurant payments. Today it works with thousands of restaurants across the United States, France, and the United Kingdom.
What sunday Does
sunday started in 2021. It was built by restaurant people, not just techies. The founders include Victor Lugger, Tigrane Seydoux, and Christine de Wendel. Lugger and Seydoux are the team behind Big Mamma, a well-known European restaurant group. They knew the pain of slow bills first-hand. So they built a fix.
The product is easy to use. A guest scans a QR code on the table. The full bill appears on the phone. The guest can split the bill, add a tip, pay, and even leave feedback. The whole thing takes a moment. Restaurants like it because tables clear faster. Faster tables mean more guests served and more sales in a night. The tool also gives owners useful reports about their business.

Why Killing the Paper Check Worked
The paper check is old and slow. A waiter prints it, brings it, waits, takes a card, walks away, and comes back. Each step wastes time. sunday cut all of that. The guest pays straight from the table. This small change has a big effect. It speeds up the busiest moment of a meal. It also makes tipping easy, which can help staff earn more.
Scale matters too. sunday now handles more than $4 billion in payments each year. It serves over 80 million guests annually and powers more than 3,000 restaurants. That kind of volume shows the idea works in the real world, not just on paper. By removing friction at checkout, sunday turned a boring task into a smooth one. This focus on smooth digital payments is part of a bigger fintech wave. To see how new tech can also face pushback, read about the AI traffic cameras that sparked a backlash in the U.S.
