Everyone wants to build the next app. But software is getting cheaper by the month, and a clever app on its own is easy to copy. The harder thing to compete with is something physical that a piece of software quietly makes ten times better. So here's a candidate for the most future-proof business I can think of: a laundrette.
It started as a very personal problem
I'm an introvert. When I lived in a shared house, we had our own kitchens and bathrooms but one shared washing machine, and it sat in a communal kitchen. I'd genuinely dread opening that door, because what if someone was already in there? I'd have to make small talk, or worse, find the machine taken and slink back with my laundry. So I'd just avoid the whole thing.
That feeling is everywhere. Student halls are the classic version: you lug a heavy bag all the way down to the laundry room, and half the time every machine is going, so you carry it all the way back up again.
The simple fix
So why not a simple tracking system? Show people how many machines are free right now, how long is left on the ones that are running, and let them book a slot ahead. That's it. Nothing exotic, just removing the uncertainty and the wasted trips.
Two very different customers will pay for it
Laundrettes. Add the tracking, put a card reader on the machines so nobody's hunting for coins, and people know exactly when to turn up. Less waiting, more turnover. Some London operators already run 24-hour delivery laundry on top of this. Done well, you could realistically double the revenue of an ordinary laundrette.
Landlords and student accommodation. This is the one most people miss. Sometimes a tenant just wants the kitchen to themselves for an hour, no drama, just a bad day. It's awkward to text the group chat "please don't come in, I need alone time." But booking a slot? That's normal, and it quietly does the same thing. It takes the emotion out of something that should be objective. Dissatisfaction goes down, tenant retention goes up, and retention is exactly the number a landlord will pay to improve.
The real principle
The point isn't laundry. It's the formula. Take a technology as new as AI and bolt it onto something as old and boring as a laundrette, and you get something genuinely powerful, and something that is very hard to make redundant. The app alone gets copied. The app welded to a real, physical, in-demand service does not.
The takeaway
Don't chase the shiniest software idea. Find something stubbornly physical that people already use, then use AI to remove its biggest friction. That combination, new tech plus old trade, is where the durable money is.
