The Best School Software Is Invisible

Nobody has ever sent me a thank-you note for a register that added up.

I've spent the last several years building software for schools — timetables, teaching assignments, gate logistics, the pipelines that carry a message from a head teacher to ten thousand parents. And the strange truth of this work is that when it goes well, it disappears. The parent gets the text about the half-day. The substitute teacher is in the right room by 8 a.m. The term runs. No applause, because nothing went wrong. That silence is the product working exactly as designed.

It took me a while to make peace with that. We're trained to want visible wins — the slick dashboard, the feature demo that makes a room lean in. But schools don't need theatre. They need the boring thing to happen, every single day, without fail, for years. The measure of school software isn't how impressive it looks in a pitch. It's whether a tired administrator at the end of a long term still trusts it enough not to keep a backup spreadsheet "just in case."

Trust is the whole product

In most institutions, the real operating system isn't software at all. It's a person — the deputy who knows which teacher covers which class, the secretary who remembers which parents actually read their messages. When you build software for a school, you are asking that person to hand part of their memory to a machine. They will only do it if the machine is right every time. One missed message, one timetable clash on the first day of term, and the spreadsheet comes back out of the drawer. Trust is expensive to earn and cheap to lose.

So I optimize for the unglamorous things:

Building where the network is the hard part

A lot of education technology is designed in places with fast, cheap, always-on internet, and it shows. It assumes apps will be downloaded, notifications will be seen, data will be plentiful. In much of the world that's simply not true. A parent may share one phone across a household, top up data in small amounts, and go offline for stretches. If your only channel is a push notification inside an app they rarely open, you haven't reached them. You've reached their lock screen.

This is why so much of my work comes back to SMS. It's old, it's unglamorous, and it lands — on every phone, without an app, without data. Designing good SMS systems is its own craft: how to phrase a message that survives being cut to 160 characters, how to send to thousands of numbers reliably and affordably, how to know a message was actually delivered. None of it photographs well. All of it matters more than the dashboard.

Why I keep doing it

Because the stakes are quietly enormous. A school that runs well gives a child a steady day. A parent who gets the right message on time can plan their work, show up, stay involved. The software I build will never be the reason a student succeeds — but a hundred small failures of communication and logistics can absolutely be the reason a system frays. I'd rather spend my career removing those small failures one at a time than building one more thing that demos well and breaks in the field.

The best school software is invisible. Nobody thanks the system that simply worked. That's not a disappointment. That's the entire point.
