Proposal writing handled by a workflow engine, with a human signing rather than writing. Aimed at construction estimators, going after the low-value tail everyone else skips.
In short: Workflow Proposal Builder for Construction is a workflow engine aimed at construction estimators, covering proposal writing. It scores 74/100 on AltF Ideas, carried by monetisation (96) and held back by timing (43). Typical pricing is $13k–$187k per customer per year, with a first version reachable in six to twelve months for $43k–$95k.
Construction teams lose proposals rebuilt from scratch that are 80% identical. Every construction team solves this the same way: someone stays late. Whoever knows how it works becomes a single point of failure.
Point a workflow engine at proposal writing, and let people review output instead of producing it. Revenue is managed service, which suits a buyer who wants the cost to track the value rather than the seat count.

| A spreadsheet | The real incumbent in most of the market, and it is free |
| A vertical competitor | Priced and scoped for enterprise accounts, not this segment |
Accuracy is unforgiving here — one wrong output costs more than the subscription.
