Sizing a market is arithmetic, and you can do the first pass yourself — below, on real Portuguese denominators. What arithmetic cannot tell you is whether anyone will actually buy, at what price and through which channel. That part needs a live pilot, and it is the part we are for.
Tell us which questions are actually open for you. Everything else is padding, and padding is how a research report becomes something nobody reads twice.
If a document cannot be acted on within a week of delivery, we do not produce it.
Who plays in your category, what each one occupies, where the gaps are and which of them are gaps for a reason.
The band the market buys in, what it currently pays for the alternative, and the justification for where you sit in it.
Which channels get tested, with what budget, over what period and against which success criteria agreed in advance.
Cost per lead, cost per customer, conversion and sales cycle length — measured, not modelled. These replace the assumption you set in the sizer above.
Vetted counterparties with contacts and the status of each conversation, rather than a list scraped from a directory.
What to do next, in what order and with what resources — built on your data rather than on category averages.
The share you assumed decides the whole answer, and it is the one figure nobody can verify from a desk. That is what a pilot is for, and where the conversation usefully starts.
