A narrow optimisation engine scoped to scheduling alone — no platform, no migration, no six-month rollout. Aimed at hvac & plumbing owner-operators, writing down what only one person knows.
In short: HVAC & plumbing Scheduling is an optimisation engine aimed at hvac & plumbing owner-operators, covering scheduling. It scores 71/100 on AltF Ideas, carried by monetisation (93) and held back by feasibility (26). Typical pricing is $4.7k–$101k per customer per year, with a first version reachable in six to twelve months for $40k–$136k.
HVAC & plumbing teams lose a calendar rebuilt by hand every time one job slips. It is the kind of task that is too small to fund and too costly to ignore. The cost is invisible on any P&L line, which is why it never gets fixed.
Point an optimisation engine at scheduling, and let people review output instead of producing it. Revenue is per-outcome, which suits a buyer who wants the cost to track the value rather than the seat count.

Solver capacity that once needed a research budget now runs on commodity hardware. HVAC & plumbing is growing at roughly 16% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| A vertical competitor | Priced and scoped for enterprise accounts, not this segment |
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
| A spreadsheet | The real incumbent in most of the market, and it is free |
Every customer wants their own edge cases encoded, so onboarding cost is the real constraint.
An idea you cannot act on is entertainment. Four concrete steps, wired to tools already running on AltFTool.
