A long-context reviewer that sits beside the existing system, reads what it already produces, and closes RFP response. Aimed at construction owner-operators, at a tenth of what the enterprise suite charges.
In short: Construction RFP Responder on Long context is a long-context reviewer aimed at construction owner-operators, covering RFP response. It scores 73/100 on AltF Ideas, carried by demand (91) and held back by moat (52). Typical pricing is $2.5k–$51k per customer per year, with a first version reachable in six to twelve months for $44k–$139k.
Construction teams lose a 200-question RFP answered by six people over a week. A typical construction operation runs this on people, memory, and a shared spreadsheet. The cost is invisible on any P&L line, which is why it never gets fixed.
A long-context reviewer that handles RFP response end to end and hands a human the exceptions rather than the queue. Revenue is usage-based, which suits a buyer who wants the cost to track the value rather than the seat count.

Million-token context windows made whole-document reasoning possible in one pass. Construction is growing at roughly 20% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
| A spreadsheet | The real incumbent in most of the market, and it is free |
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
The buying cycle is slower than the build, so runway assumptions matter more than code.
