sunday Secures $21M Series B to Accelerate U.S. Expansion, Bringing Disruptive Payment Technology to Restaurants Nationwide

sunday, the built-by-restaurateurs payment solution company reinventing restaurant hospitality, has raised a $21 million Series B funding round, with participation from DST Global Partners, to continue its explosive growth.

The new investment follows a year of hypergrowth. sunday has tripled in size, as its alternative to traditional payment terminals becomes the new standard. From Michelin-starred restaurants to fast casual, sunday is used at hotspots and renowned restaurant groups like Au Cheval, Dishoom, TAO, Parker Hospitality, Lettuce Entertain You, Bareburger, La Pecora Bianca, Boqueria and many more. 

Founded in 2021 by Christine de Wendel (US CEO), alongside Victor Lugger (CEO) and Tigrane Seydoux (the entrepreneurs and foodies behind the esteemed European restaurant group, Big Mamma, which is set to land in Miami this year), sunday was born from a simple idea: paying at a restaurant shouldn’t be the worst part of the meal.

sunday started as a fast, simple way to pay, and has since evolved into a full platform connecting every guest interaction: ordering, payment, loyalty, and CRM. It is transforming the inefficient payment experience into a growth engine for restaurants, while simultaneously benefiting guests through simplified and quicker transactions. 

Its adoption by restaurants is not theoretical; it’s measurable. For restaurant operators, using sunday leads to faster turnover (average of 12 minutes per table), higher revenue, increased tips (11% average increase in US), loyalty, data, and Google reviews (5x more reviews on average). Having sustained exponential growth since launch, sunday is currently used by 3,000+ restaurants globally with a strong presence across the U.S., U.K, and France.

“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.”

The strategic raise comes at a time of explosive growth for sunday, as it experiences 3x year-over-year growth. In just 12 months, sunday has tripled revenue, processes over $4 billion annually and has been used by over 80 million diners. By the end of this year, sunday will be the most adopted guest engagement platform in the industry, on track to become the default for modern hospitality.

This capital will be used to accelerate growth in the U.S., which has become sunday’s #1 market. In fact, sunday is actively expanding in the US, with new launches in Los Angeles, Austin, D.C., Philadelphia, Dallas, Denver, Las Vegas, and Boston. sunday will power multiple verticals, including smart kiosks built for high-volume fast casuals, to a dedicated solution tailored for Michelin-starred and James Beard Award-winning restaurants.
