Meet Sunday, a new startup that is going to attract some headlines as it has raised a $24 million seed round at a $140 million post-money valuation. That’s a lot of money for a company that started just a few months ago but that’s because Sunday wants to move quickly.

Sunday is getting noticed because it is founded by Victor Lugger, Tigrane Seydoux and Christine de Wendel — Lugger and Tigrane have been working together for several years as they’re the founders of Big Mamma. Christine de Wendel headed Zalando in France before joining ManoMano as COO.

If you’re not familiar with Big Mamma, they’ve launched a dozen Italian restaurants in France. They also manage La Felicità, the food court at Station F.

Some people love those restaurants because the food is good and it’s relatively affordable. Some people hate it because Big Mamma is also particularly well known for its long queues and the fact that you always feel like you have to eat quickly for the next group. But it’s clear that it’s been working well for the past few years.

Managing Big Mamma during a pandemic led to Sunday, a spin-off company incorporated in the U.S. The restaurant company wanted to offer a way to check the menu and pay without touching anything. Like many restaurants, they put QR codes on the tables to that customers can scan them with their phones and load a website.

But Sunday didn’t stop at the menu as it also connects directly to the cash register system. Sunday supports Oracle Micros, Brinks, Tiller, Zelty, Revo, CashPad, etc. This way, clients can also scan the QR code, check their tab and pay directly from their phone. When they’re done eating, they can pay by themselves, stand up and leave.

After trying Sunday in Big Mamma restaurants, the company saw some encouraging results. 80% of customers chose to pay using the QR code, which means that restaurants saved 15 minutes in wait time on average leading to a better table turnover rate.

And this is key to understanding Sunday. It’s easy to sell a new payment system to a restaurant if it leads to more revenue. Popular restaurants that feel like they’re always looking for empty tables could greatly benefit from Sunday.

It also opens up some new possibilities. For instance, guests can split the bill directly at the table — everyone loads up Sunday and pay. Sunday is based on QR codes right now, but the company isn’t attached to QR codes specifically. You could imagine loading your bill using RFID chips, a tablet, etc.

The vision is clear — Sunday wants to build the Fast Checkout of restaurants. The startup thinks online checkout is going to merge with offline, brick-and-mortar checkout.

Sunday customers don’t pay any monthly subscription fee or setup fee. You only pay processing fees based on usage. And those fees tend to be lower than the card machine you’re currently using.

The startup’s seed round was led by Coatue with New Wave participating. New Wave is a new European seed fund led by Pia d’Iribarne and backed by Xavier Niel. Multiple hospitality and tech investors are also participating.

The idea is to raise a lot of money, sign up a lot of restaurants and take over the market right now while there’s an opportunity during the pandemic. They have hired 40 people already and they’re signing deals with restaurants even though most of them are still closed in Europe.

Sunday isn’t a tech achievement per se — it’s an execution play. The company that can roll out this kind of checkout experience faster than the others is going to take over the market.

When restaurants are going to be open again, you may notice Sunday QR codes in France at Eataly, PNY, Paris Society, Eric Frechon, Groupe Bertrand’s restaurants (Burger King France, Hippopotamus, Groupe Flo…). Similarly, in the U.K., Sunday is partnering with JKS Group (Hoppers, Brigadiers, Gymkhana…), Corbin & King and others. Sunday is also talking with companies in the U.S. and Spain.

Overall, there are more than a thousand restaurants currently adopting Sunday.

“We follow the same model as the one we used when launching restaurants with Big Mamma. Seven years ago, we invested three times more than the others to compress fixed costs and deliver a better product,” Sunday co-founder and CEO Victor Lugger told me.

The startup already has an ambitious product roadmap. Eventually, you could imagine having your own Sunday account that remembers your past bills, tracks your allergies, saves your favorite payment method, etc. Once again, it’ll come down to execution.
