Driving lesson waitlist

A text-message waitlist for independent driving instructors, so a lesson cancelled the night before goes to a learner who wants an extra one.

Launchifier is a guided path: five stages, 45 tasks, and a go/no-go gate at the end of each stage. Below is every task this founder was given, what they did, and what the guide decided.

The idea, as the founder entered it

“I'm a driving instructor in Cork with my own car and about forty learners at a time. Every week two or three lessons get cancelled the night before, and that's money gone, because by the time I've rung around the slot has passed. Loads of my learners would happily take an extra lesson at short notice before their test. I want something that offers a cancelled slot to my waiting learners automatically, so the first one to say yes gets it. I'd spend €500 on it.”

What the founder did: spoke to 8 other independent instructors in Cork and Limerick, found through the national instructor register and two instructor groups online. All 8 lose lessons to late cancellations, most between 2 and 4 a week at €40–50 each. 5 of 8 said they'd pay €15 a month if it filled even one slot a week.

What the guide flagged: the founder first described a full booking system. Instructors already use Setmore, Calendly or a paper diary, and none of them wanted to switch. The gap was narrower: none of those tools offer a cancelled slot to a waiting list automatically. The guide suggested building only that, alongside whatever diary each instructor already keeps.

Why Go: a weekly, countable loss (2–4 slots × €45 is €90–180 a week), a stated price, and buyers the founder sees at every test centre. Weak spot noted: each instructor is a small customer, so the tool has to cost almost nothing to run.

What got cut: 8 features became 3. Cut: online booking, payments, a learner app, test-date tracking, lesson notes and reviews. Kept: the instructor marks a slot free, waiting learners get a text in the order they joined, and the first to reply yes gets it, while everyone else is told it's gone.

Why Go: the three features cover the whole complaint and nothing the instructor already does elsewhere. The target is concrete: fill half of all late cancellations in the first month. It fits in about a tenth of the budget, with plenty left over for text costs.

Core user flow

Learner cancels → instructor taps "slot free" → waiting learners texted in order → first "yes" gets it → others told it's gone.

Explicitly not in v1

Booking, payments, lesson notes, a learner app. Learners never log in; they just reply to a text.

Build path chosen: an AI app builder plus a texting service, no custom code. Irish mobile numbers and text prices were checked first, because many cheap texting plans only cover North America. At about €0.07 a text, a month of waitlist offers costs the instructor less than €5.

What the guide flagged: the first users are the founder's own learners, many of them 17. The guide flagged collecting only a first name and a phone number, and letting learners leave the list by replying STOP, which Irish rules on marketing texts expect anyway.

What the guide flagged: the launch plan is the founder's own forty learners for three weeks, then the 5 instructors who said they'd pay. Success is half of late cancellations filled. The readiness check will cover what happens when a text fails to send, and who owns the number.

What this run got right

The founder knew the loss to the euro and found eight other instructors who felt it too. The useful move was refusing the booking system: a narrow waitlist doesn't compete with anyone's diary, so an instructor can try it without changing anything else about how they work.

What we’d watch

One instructor is a tiny customer at €15 a month. To be worth running, this needs dozens of instructors, and they're spread across the country. Learn will show whether instructors tell each other about it, or whether every sign-up takes a phone call from the founder.

Have an idea like this?

Run it through the same five stages. The first one is free, and you’ll know by the end whether to keep going.
