Septic service reminders

A reminder tool for small septic pumping companies that tracks when each customer's tank was last pumped and texts them when it's due, so routine jobs get booked before they turn into emergencies.

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've dispatched trucks for a septic pumping company outside Dayton, Ohio for eleven years. A tank should be pumped every three years or so, but almost nobody remembers, so they call us when it's backing up into the basement. Then it's an emergency, the customer is upset, and we rearrange the whole week. I want to build something that remembers when each customer was last pumped and reminds them before it's a problem. My boss says he'd use it, and I know other owners who would too. I can put about $1,200 into it.”

Validate

Is this a real problem for a customer you can reach, who wants it solved?

What the founder did: called 8 owners of septic companies across Ohio and Indiana, most of them people the founder already knew from county permit offices. All 8 track pump dates somewhere: paper cards, a spreadsheet, or the office manager's memory. None send reminders consistently. 6 of 8 said they'd pay $40–60 a month for something that did it for them, and two said emergency calls were their biggest source of overtime.

What the guide flagged: the founder's first plan was full dispatch software. Jobber, Housecall Pro and ServiceTitan already do scheduling, invoicing and routing, and the owners who had tried them called them too much for a three-truck shop. The one gap every call mentioned was that nobody reminds customers when a tank is due. The guide suggested building only that, next to whatever each company already uses.

Why Go: a recurring, countable loss (owners estimated 30–50 routine jobs a year that turn into emergencies or go to a competitor), a stated price from 6 of 8 owners, and a founder who already talks to these buyers every week. Weak spot noted: some owners avoid software entirely, so setup has to take minutes, not an afternoon.

What got cut: the founder started with 9 features: a dispatch board, route planning, invoicing, online payments, a customer portal, a technician app, inspection reports, reviews and reminders. Everything except reminders was cut. Invoicing and the portal were the close calls. Both went to Later, because every owner already has a way to bill and none of them asked for a portal.

Why Go: the first version does the one job the owners asked for and touches nothing they already rely on. It fits the budget with most of it left over, and it can run at the founder's own company before anyone else is asked to pay.

Core user flow

Owner uploads a customer list with last pump dates → app works out who's due → customer gets a text a month ahead → they reply to book → the office gets the request.

Explicitly not in v1

Scheduling, invoicing, payments, a technician app. Customers never log in. The office keeps using its own calendar.

Can you build it with AI tools without losing control?

Gate: Go. Get ready to launch.

Build path chosen: an AI app builder with a text-messaging service and a spreadsheet import, no custom code. The founder priced a freelancer first, but the quotes started at $3,000, more than twice the budget. The builder handled the import and the "who's due" logic in a weekend. Getting text replies to land in the right customer record took three more evenings.

What the guide flagged: pump dates in real customer lists are messy, so a clean sample list would hide the hardest part. The founder tried the import with three owners' actual spreadsheets. Two of the three broke on dates written as "spring 2023" or "after the flood". The fix, asking the owner to confirm any date the app can't read, went in before launch.

What the guide flagged: the readiness check found two holes before launch: replies of "STOP" weren't turning reminders off, which US texting rules require, and the customer lists had no copy outside the builder. Both were fixed the day before launch. The founder also moved the texting number into the company's name rather than a personal account.

What happened at launch: launched first at the founder's own company, with 1,400 customers imported. In the first two weeks, 212 reminder texts went out and 31 customers booked a routine pump. The founder then offered it to the 6 owners who'd said they'd pay. 4 tried it, and 3 signed up at $49 a month.

What the numbers said: after three weeks, 15% of texted customers booked within a week. Last year, in the same months, about 2% of those customers called on their own before something went wrong. At the founder's company that is 31 routine jobs that would have been emergencies, or gone to someone else.

What the guide flagged: the number to watch isn't bookings, it's whether owners keep their lists current. Two of the three paying companies haven't added a pump date since signing up. If that holds, reminders go stale within a year, and the product needs a way to pick up dates from jobs the office already records.

What this run got right

The founder came in wanting to replace dispatch software and left with the one feature the big tools skip. Eight calls to people they already knew did that. Running it at their own company first meant there were real booking numbers on the table before any other owner was asked to pay.

What we’d watch

Three paying companies is a start, not proof. If owners stop updating pump dates, reminders dry up and so does the value. Learn will decide whether to pull dates in from the tools owners already use, or to accept this as a small, steady business run alongside the day job.
