A long-context reviewer that sits beside the existing system, reads what it already produces, and closes proposal writing. Aimed at wholesale inventory planners, built for one person, not a department.
In short: Proposal Builder Built for Inventory Planners is a long-context reviewer aimed at wholesale inventory planners, covering proposal writing. It scores 76/100 on AltF Ideas, carried by moat (86) and held back by open field (61). Typical pricing is $2.2k–$44k per customer per year, with a first version reachable in about a month for $5.5k–$20k.
Wholesale teams lose proposals rebuilt from scratch that are 80% identical. Nobody owns this process, which is exactly why it keeps breaking. Whoever knows how it works becomes a single point of failure.
Point a long-context reviewer at proposal writing, and let people review output instead of producing it. Revenue is usage-based, which suits a buyer who wants the cost to track the value rather than the seat count.

| Who | The gap |
|---|---|
| A generalist AI tool | No domain grounding, so output needs full human review |
| A spreadsheet | The real incumbent in most of the market, and it is free |
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
The incumbent is a person, and displacing a person is a change-management problem.
