Proposal writing handled by a long-context reviewer, with a human signing rather than writing. Aimed at accounting firm owners, built for one person, not a department.
In short: Proposal Builder for Accounting Firm Owners is a long-context reviewer aimed at accounting firm owners, covering proposal writing. It scores 71/100 on AltF Ideas, carried by demand (91) and held back by feasibility (23). Typical pricing is $14k–$203k per customer per year, with a first version reachable in six to twelve months for $40k–$130k.
Accounting teams lose proposals rebuilt from scratch that are 80% identical. Nobody owns this process, which is exactly why it keeps breaking. The error rate is tolerated because measuring it would cost more than the errors.
A long-context reviewer that handles proposal writing end to end and hands a human the exceptions rather than the queue. Revenue is managed service, 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 |
| An internal hire | Works until volume doubles, then breaks again |
The incumbent is a person, and displacing a person is a change-management problem.
