The productised services businesses growing fastest in 2026 share a property that reads as a limitation: they serve a buyer so specific that describing the market takes a full sentence with three qualifying clauses.
Specialised video editing for SaaS companies. Architectural CAD for eco-focused practices. Landing pages for fintech. SEO for local service businesses. Each of those could have been broader. None of them are, and that is why they work.
The four things narrowness buys you
Test 1
Can you name where fifty of these buyers are gathering this week?
Test 2
Can you describe their current workaround precisely?
Test 3
Would they recognise themselves in a single sentence?
Then
Deliver forty times, and the mechanical parts become your product spec
Fixed scope becomes possible. Variance across engagements is what makes fixed pricing dangerous, and variance falls sharply when the buyer is homogeneous. After twenty near-identical engagements you know the distribution of effort well enough to price it confidently.
Sales cycles shorten. A prospect who sees their exact situation described stops evaluating whether you can help and starts evaluating whether to start. That skips the most expensive part of the sales process.
Referrals compound. Micro-specialists get referred more, because the referrer's risk is lower. Recommending a generalist requires judgement about fit. Recommending the person who does exactly this one thing for exactly this kind of company does not.
“A productised service at $4,000 a month needs twenty-five clients for a million a year. Out of four thousand businesses, that is six-tenths of one percent.”
Delivery gets cheaper without getting worse. Repetition produces assets, templates, and shortcuts that are only reusable when the work is similar. A generalist rebuilds from scratch every time and never gets the compounding.
The objection everyone raises
A productised service at $4,000 a month needs twenty-five clients for a million a year.
The market is too small. It is almost never too small, and the arithmetic is usually not run before the objection is raised.

Join the WaitlistA productised service at $4,000 a month needs twenty-five clients to reach a million a year. If your specific buyer type numbers four thousand businesses, you need six-tenths of one percent of them. That is not a market size problem. It is a distribution problem, and distribution is far easier into a narrow market than a broad one, because you can name the places those four thousand businesses gather.
How to choose the narrowness
Narrow on the buyer's context, not on the service. 'Positioning' narrowed to 'positioning workshops' is still broad, because the buyer could be anyone. 'Positioning for B2B SaaS companies post-Series A whose founder still writes the website copy' is narrow on context and immediately suggests where to find them.
Three tests: can you name where fifty of them are this week, can you describe their current workaround precisely, and would they recognise themselves in one sentence? Three yeses means the narrowness is real rather than cosmetic.
The progression past services
Micro-specialisation is also the cleanest route to software, because a service delivered forty times to near-identical buyers has already revealed which parts are mechanical and which require judgement. The mechanical parts are the product specification, written for you by the work.
Every venture in our showcase followed some version of that path. See productise your consulting for the service-side mechanics.
