Sunday, the payment platform built by restaurateurs, has raised $21 million in a Series B funding round led by DST Global Partners to accelerate its US expansion.

Founded in 2021 by Christine de Wendel (US CEO), Victor Lugger and Tigrane Seydoux, Sunday aims to simplify restaurant payments and enhance guest experiences. The platform goes beyond payments, connecting ordering, loyalty and customer relationship management into a single system.

Sunday plans to use the new funding to solidify its position as the leading guest engagement platform in the US and continue redefining the restaurant payment experience.

Sunday is currently used by more than 3,000 restaurants globally, including Michelin-starred and fast-casual establishments such as Au Cheval, Dishoom, TAO and Parker Hospitality. Its adoption has helped restaurants increase table turnover, boost revenue, and drive higher tips and customer engagement, including a fivefold increase in Google reviews on average.

The company has tripled in size over the past year, processing over $4 billion annually and serving more than 80 million diners. With US adoption as its primary focus, Sunday is expanding to Los Angeles, Austin, DC, Philadelphia, Dallas, Denver, Las Vegas and Boston.

The platform will cater to both high-volume fast casuals and fine-dining establishments.

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.”
