Why is this ranked differently from the main list?
This page re-scores the corpus using a weighting tuned for developers: moat 24%, demand 22%, money 18%. The same six signals, weighted for a different situation.
A narrow long-context reviewer scoped to contract analysis alone — no platform, no migration, no six-month rollout. Aimed at manufacturing quality teams, writing down what only one person knows.
RFP response handled by a retrieval engine, with a human signing rather than writing. Aimed at energy ops teams, starting from data the business already produces.
A document parser that handles reporting & analytics end to end and hands a human the exceptions rather than the queue. Aimed at energy compliance leads, closing the loop while everyone is asleep.
A forecasting model that sits beside the existing system, reads what it already produces, and closes maintenance planning. Aimed at waste management ops teams, charging only when it actually works.
A narrow document parser scoped to reconciliation alone — no platform, no migration, no six-month rollout. Aimed at manufacturing quality teams, finding what the inspector would find, first.
Manufacturing/Per-outcome/$3.9k ACV/~1 quarter
A vision model that handles asset tracking end to end and hands a human the exceptions rather than the queue. Aimed at manufacturing maintenance leads, at a tenth of what the enterprise suite charges.
Manufacturing/Site licence/$8.1k ACV/6-12 months
An anomaly detector that sits beside the existing system, reads what it already produces, and closes inventory planning. Aimed at manufacturing maintenance leads, going after the low-value tail everyone else skips.
Manufacturing/Per-outcome/$4.0k ACV/6-12 months
A narrow voice agent scoped to field reporting alone — no platform, no migration, no six-month rollout. Aimed at manufacturing maintenance leads, holding service constant on a smaller team.
A retrieval engine that handles customer support end to end and hands a human the exceptions rather than the queue. Aimed at industrial services field supervisors, finding what the inspector would find, first.
Document review handled by a retrieval engine, with a human signing rather than writing. Aimed at industrial services owner-operators, charging only when it actually works.
Contract analysis handled by a retrieval engine, with a human signing rather than writing. Aimed at energy ops teams, starting from data the business already produces.
Energy/Site licence/$11k ACV/~1 quarter
A narrow autonomous agent scoped to customer support alone — no platform, no migration, no six-month rollout. Aimed at energy ops teams, finding what the inspector would find, first.
Energy/Per-outcome/$4.7k ACV/6-12 months
Energy/Per-outcome/$5.3k ACV/6-12 months
Energy/Managed service/$14k ACV/6-12 months
RFP response handled by a long-context reviewer, with a human signing rather than writing. Aimed at energy compliance leads, catching the error before it becomes a change order.
Energy/Managed service/$13k ACV/6-12 months
An autonomous agent that sits beside the existing system, reads what it already produces, and closes onboarding. Aimed at energy asset managers, finding what the inspector would find, first.
Energy/Managed service/$13k ACV/6-12 months
A narrow forecasting model scoped to collections alone — no platform, no migration, no six-month rollout. Aimed at solar project managers, taking the phone queue off a human entirely.
Solar/Per-outcome/$4.2k ACV/6-12 months
Point an optimisation engine at site selection, and let people review output instead of producing it. Aimed at solar project managers, holding service constant on a smaller team.
Solar/Per-project/$2.6k ACV/6-12 months
A voice agent that handles intake & triage end to end and hands a human the exceptions rather than the queue. Aimed at solar ops teams, so the work stops following people home.
Solar/Per-project/$2.6k ACV/6-12 months
A narrow anomaly detector scoped to risk assessment alone — no platform, no migration, no six-month rollout. Aimed at utilities ops teams, catching the error before it becomes a change order.
Utilities/Per-outcome/$4.5k ACV/6-12 months
A retrieval engine that sits beside the existing system, reads what it already produces, and closes compliance audit. Aimed at utilities compliance leads, so the work stops following people home.
Utilities/Data subscription/$5.4k ACV/6-12 months
A retrieval engine that sits beside the existing system, reads what it already produces, and closes grant & funding tracking. Aimed at utilities field supervisors, writing down what only one person knows.
A narrow long-context reviewer scoped to document review alone — no platform, no migration, no six-month rollout. Aimed at waste management ops teams, so the work stops following people home.
Waste management/Flat SaaS/$900 ACV/6-12 months
A retrieval engine that sits beside the existing system, reads what it already produces, and closes claims & appeals. Aimed at waste management fleet owners, catching the error before it becomes a change order.
RFP response handled by a long-context reviewer, with a human signing rather than writing. Aimed at waste management route planners, so the work stops following people home.
Scheduling handled by an optimisation engine, with a human signing rather than writing. Aimed at agriculture growers, so the work stops following people home.
