ATLANTA–(BUSINESS WIRE)–sunday, the payment platform built by restaurateurs that’s reinventing restaurant hospitality, has raised a $21 million Series B funding round, with participation from DST Global Partners.

This new investment follows a year of hypergrowth. sunday has tripled in size, as its alternative to traditional payment terminals becomes the new standard: from the coolest burger joints in America, like Au Cheval, to Michelin-starred icons like Apicius or Imperfecto, cult favorites like Dishoom, global nightlife leaders like TAO, sun-soaked destinations like Gigi in Saint-Tropez, and leading multi-brand groups like Lettuce Entertain You and Gibsons.

“Guests who pay with their phone behave just like they would in other digital experiences — they leave feedback, rate their experience, and generate data. And with the rise of AI, that unlocks an incredible amount of insight. Compared to traditional reservation platforms, sunday provides 11 to 13 times more guest feedback — instantly. It’s a game changer for hospitality.” said Victor Lugger, co-founder of sunday.

Founded in 2021 by Christine de Wendel (U.S. CEO), alongside Victor Lugger and Tigrane Seydoux (the entrepreneurs behind the esteemed European restaurant group, Big Mamma, which is set to land in Miami later this year), sunday was born from a simple idea: paying at a restaurant shouldn’t be the worst part of the meal. Just like hailing a cab or booking a table, technology can fix the checkout experience too.

sunday started as a fast, simple way to pay, and has evolved into a full platform connecting every guest interaction: ordering, payment, loyalty, and CRM. sunday does not pile on more tech; it partners with the tools restaurants already use and make them work together. Seamlessly.

Real-World Results

Over 80 million diners have paid with sunday, from Girafe in front of the Eiffel Tower, to Rubirosa in New York, or Boathouse in Orlando’s Disney Springs. Here’s what happened next:

• 83% of guests who scan a sunday QR code choose to pay with it (across 100% of clients),
• 67% have left feedback, 13x more data than reservations or ratings platforms,
• 56% have shared their email, 18x more than today,
• 34% have joined loyalty programs effortlessly, fixing one of restaurants’ hardest challenges,
• 12% have left 5-star Google reviews — a 5 to 10× increase in online ratings, marking a new era for restaurant SEO,
• Meanwhile, tip rate reached 22.8% on average (+11% vs market),
• Average check size increased by 21% with our hybrid ordering system,
• and restaurants have saved 12 minutes per table on average.

Unlike bolt-on solutions, sunday plugs directly into restaurants’ existing tech stack through 50+ integrations including Toast, Lightspeed, NCR, and Paytronix.

A Category-Defining Year: Tripling Revenue and Processing Over $4 Billion Annually

In just 12 months, sunday has grown by 3x and now processes over $4 billion annually. With 3,000+ restaurants in the U.S., France, and the U.K., sunday is now one of the world’s fastest-growing players in restaurant payments and guest experience solutions.

The U.S. has become sunday’s #1 market, with significant adoption from major restaurant groups and hospitality brands like Lettuce Entertain You, Gibsons, Hogsalt, and Innovative Dining Group. From Michelin-starred dining rooms to high-volume chains, sunday now powers every touchpoint between restaurants and guests: menus, ordering, payment, loyalty, CRM, and soon booking & delivery — all within one streamlined system.

“We’re building the category-defining platform for hospitality, one that connects every touchpoint into a single, frictionless experience.” said Christine de Wendel, co-founder and U.S. CEO. “The appetite from the industry is huge, and we’re here to lead the charge.”

Fueling the Next Phase: A Platform Built for Every Format, From Kiosks to Michelin Stars

Next year, sunday will power multiple verticals — from smart kiosks built for high-volume fast casuals, to a dedicated solution tailored for Michelin-starred and James Beard Award-winning restaurants. These accolades aren’t just awards, they’re the gold standard of hospitality. They represent the highest quality guest experience, and they set the tone for the entire industry. That’s why sunday has invested in discreet, design-led payment flows built specifically for fine dining, including QR codes on the bill, and guest data capture that enhances loyalty without compromising ambiance.

This evolution breaks the misconception that sunday is just “QR on table.” The platform today is modular, verticalized, and deeply integrated, unlocking new capabilities across:

• Fast Casual: self-serve kiosks + mobile ordering
• Casual Dining: scan-to-pay, reorder, and feedback
• Fine Dining: QR on bill, invisible payment, CRM
• Enterprise: white-labeled guest platforms, loyalty & AI

Whether it’s a 3-Michelin-star tasting menu or a burger joint serving 2,000 guests a day — sunday helps restaurants elevate service, optimize ops, and connect with every guest.

To support this multi-format ambition, sunday is doubling down on international growth. It is actively expanding in the U.S., including new launches in Los Angeles, Austin, D.C., Philadelphia, Dallas, Denver, Las Vegas, and Boston, while also entering the UAE, a booming premium hospitality market where its first major group goes live in January.

sunday is targeting doubled revenue, guest volumes, and product adoption by summer 2026.

“It’s all about better hospitality – for guests, for staff, for operators. This round lets us move faster toward that goal.” said Lugger.
