Proposal writing handled by a long-context reviewer, with a human signing rather than writing. Aimed at construction ops teams, so the work stops following people home.
In short: Proposal Builder Built for Ops Teams is a long-context reviewer aimed at construction ops managers, covering proposal writing. It scores 70/100 on AltF Ideas, carried by timing (96) and held back by feasibility (27). Typical pricing is $4.8k–$103k per customer per year, with a first version reachable in six to twelve months for $29k–$103k.
Construction teams lose proposals rebuilt from scratch that are 80% identical. The work sits between two systems that were never designed to talk. It scales linearly with headcount, so growth makes it worse rather than better.
A long-context reviewer that handles proposal writing end to end and hands a human the exceptions rather than the queue. Revenue is per-outcome, which suits a buyer who wants the cost to track the value rather than the seat count.

| Who | The gap |

| A spreadsheet | The real incumbent in most of the market, and it is free |
| A generalist AI tool | No domain grounding, so output needs full human review |
Accuracy is unforgiving here — one wrong output costs more than the subscription.
