Restaurant payments firm sunday raises $21m Series B

November 13, 2025

Restaurant payments firm sunday, which describes itself as a hospitality-focused platform built by restaurateurs, has secured fresh capital to accelerate its growth across the US market.

The company, founded in 2021 and now active across the US, UK and France, has quickly gained traction with restaurants seeking to modernise their guest experience.

The company has raised $21m in a Series B round. The investment included participation from DST Global Partners and will support its rapid expansion.

Founded by Christine de Wendel, Victor Lugger and Tigrane Seydoux – the entrepreneurs behind the European restaurant group Big Mamma – sunday began as a quick and easy way for diners to settle their bills.

It has since grown into a full hospitality platform integrating ordering, payments, loyalty and CRM, positioning itself as a technology partner for restaurants aiming to maximise efficiency and guest satisfaction.

The new funding will be used to deepen sunday’s footprint across major US cities, which it says is now its largest and fastest-growing market. The firm is rolling out its technology in cities including Los Angeles, Austin, Washington D.C., Philadelphia, Dallas, Denver, Las Vegas and Boston. It also plans to power a range of restaurant formats, from smart kiosks for fast-casual venues to bespoke systems for Michelin-starred and James Beard-recognised establishments.

Recent performance figures highlight the scale of sunday’s momentum. The company reports 3x year-over-year growth, annual processing volumes exceeding $4bn and more than 80 million diners using the platform.

Today, the platform is used by more than 3,000 restaurants worldwide, from Michelin-star venues to major hospitality groups such as Au Cheval, Dishoom, TAO, La Pecora Bianca, Bareburger and Parker Hospitality.

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