A narrow retrieval engine scoped to contract analysis alone — no platform, no migration, no six-month rollout. Aimed at hvac & plumbing owner-operators, going after the low-value tail everyone else skips.
In short: Retrieval Contract Analyser for HVAC & plumbing is a retrieval engine aimed at hvac & plumbing owner-operators, covering contract analysis. It scores 76/100 on AltF Ideas, carried by demand (94) and held back by monetisation (41). Typical pricing is $2.2k–$44k per customer per year, with a first version reachable in about a quarter for $16k–$53k.
HVAC & plumbing teams lose renewal terms nobody re-read before signing. Every hvac & plumbing team solves this the same way: someone stays late. The error rate is tolerated because measuring it would cost more than the errors.
Contract analysis handled by a retrieval engine, with a human signing rather than writing. Revenue is usage-based, which suits a buyer who wants the cost to track the value rather than the seat count.
