Everything below is the method behind a SectorIntel report, written out in plain English with worked examples you can reproduce on paper. No black boxes, no paywalled research — this is textbook practice, which is exactly the point: a market size only holds up if the person reading it can rebuild it.
The full funnel, step by step: buyer universe → served market → reachable slice, with the exact arithmetic our engine runs on a warehouse-robotics example.
Read the guide → MethodWhy each method fails on its own, how they anchor to different public numbers, and how a cross-check catches an inflated TAM before a committee does.
Read the guide → MethodWhy one number is a single point of failure, how the median beats the average, and how a spread ratio turns disagreement into an honest confidence band.
Read the guide → MethodSizing a market by the economic value it removes — labour saved, losses avoided — and the fraction a vendor can actually charge for. The third leg of the triangle.
Read the guide → DisciplineThe automated gates every figure passes before it ships: funnel monotonicity, value-pool containment, plausible capture share, price coherence, and a realistic SOM.
