A long-context reviewer that sits beside the existing system, reads what it already produces, and closes proposal writing. Aimed at construction ops teams, going after the low-value tail everyone else skips.
In short: Automated Proposal Builder for Construction is a long-context reviewer aimed at construction ops managers, covering proposal writing. It scores 74/100 on AltF Ideas, carried by moat (93) and held back by feasibility (31). Typical pricing is $4.6k–$99k per customer per year, with a first version reachable in six to twelve months for $35k–$95k.
Construction teams lose proposals rebuilt from scratch that are 80% identical. It is the kind of task that is too small to fund and too costly to ignore. Most operators assume this is simply the cost of doing business.
Point a long-context reviewer at proposal writing, 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.

| 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 |
| An internal hire | Works until volume doubles, then breaks again |
