When our second child arrived, I inherited the weekly grocery planning. I thought it would be simple. I quickly understood how long it would actually take.
You read the flyer. You spot the deals. You hesitate — "doesn't really feel that much cheaper". You trust it. You pick four recipes for the week that share a few ingredients, nothing more. You head to the store.
And there, at the counter, you realize you no longer remember how much ground beef you need for the two recipes that call for it. You grab the big pack — you really don't want to come back. Same for the onions, the tomatoes, the fruit, the vegetables. In the end, the basket costs noticeably more than expected.
Back home, you decide to cook it all at once so nothing goes to waste. A big shepherd's pie. There's more than expected. After three nights, no one wants any more — the kids included, and honestly you too. The rest ends up in the trash. And next week, you start all over again.
This tool didn't exist. So I built it — first for us, then for everyone who needed it too.
I looked for tools. There wasn't much. The only one that came close was complicated, overloaded with useless features, and expensive. So I built an Excel file.
On one side, the recipes my family loves — the ones we've been collecting from the internet for years. On the other, the week's deals. A rough algorithm that crossed the two and suggested the possible dinners.
It worked. To the point I said to myself: I can't be the only one.
"8,000 people later,
the doubt was gone."
I created a Facebook group to share my weekly lists. In two years, more than 8,000 people joined us. They were also looking for something that didn't exist.
That's when we understood Petite Liste had to exist for real. Not as a shared Excel file. As a true application — smooth, intuitive, that thinks with you while you go on with the rest of your life.
With a simple conviction: you shouldn't even have to look at the flyer. It's the tool that pulls people into the store, but it isn't what matters. What matters is the app that uses the deals intelligently for you and organizes your list.
Advertising. No one wants to see a car ad in the middle of their grocery list, or during a grocery run. It will stay that way for as long as we exist.
Selling data. Your grocery habits are none of our business — and even less the highest bidder's. Your data stays yours.
Traps. No deliberately frustrating free version. No disguised commitments. If you pay, it's because you love the product — and you can leave whenever you want.
Petite Liste isn't yet another app. It's the tool we wanted for ourselves — that we share today with those who, like us, no longer have time to waste on a flyer.
