One Percent of What, Exactly?

You have done the arithmetic on the back of something. There are a few hundred thousand people in your profession, one percent is a few thousand, and a few thousand at a professional price is a number that made you sit up.

The percentage is not the problem. One percent of a real market is a sane target and plenty of businesses have been built on less.

The problem is the other number. Because the figure you multiplied by was the licensed population of an entire profession, and that is not a market. It is a headcount.

Between that headcount and a person who could actually buy from you sit five filters, and every one of them is subtractive.

Filter one: specialty

You are not selling to your profession. You are selling to a part of it.

An article on cash-pay practice does not address hospital employees. A course on commercial work does not address people who only do residential. A guide to a particular technique reaches the people who use that technique.

This is the filter everybody accepts in principle and nobody applies to their own arithmetic. Ask which subset of the profession your material is genuinely written for, and use that number instead. It will be smaller by an order of magnitude and it will be true.

Filter two: career stage

Almost every good course idea is stage-specific.

The first ninety days of independent practice. The transition into supervision. The move from employed to owning. Preparation for a particular exam. Whatever it is, the people to whom it is urgent occupy a window, and everybody either side of that window is not a buyer — they either already solved it or have not reached it.

Which also means your market refreshes, since people keep arriving at that stage. But at any given moment it is a slice, not the whole.

Filter three: do they actually have the problem?

Of the people left, how many are experiencing the specific difficulty your course addresses?

This is prevalence, and it is the single biggest determinant of whether anybody buys. Some problems touch nearly everybody at a given stage. Others touch a fifth of them. The difference between those two decides whether your business is viable, and it is knowable — you can ask, and you should, in whatever forums and groups your profession uses.

Filter four: are they willing to do anything about it?

This is the uncomfortable filter, and nobody puts it on the napkin.

Of the people who have the problem, how many will actually put in the work to solve it? Some proportion of every profession would rather have the problem than do a course about it. They are tired, or comfortable, or scared, or they would genuinely rather just go to their job and come home. That is not a moral failing and it is not something you can market your way out of.

You need the ones who buy books, attend the optional session, and have already tried three things that did not work. In some professions that is a large share. In others it is not, and you know which yours is even if you have never said it out loud.

Filter five: can you reach them at all?

Last, and the one that turns a market into a business.

Somebody who has the problem, wants it solved, and has the money is still not addressable if there is no way to put anything in front of them. They are not in a group, not on a list, not searching for this, and not reading anything you could plausibly appear in.

So the honest question is not how many exist. It is how many are somewhere you can get to — an association, a forum, a search term, a platform where they can be targeted by profession.

This filter is also the one you can change. Everything above is a fact about the world; reach is a thing you build over years.

The number you end up with

Run all five and the figure is much smaller than the one you started with. That is the point of the exercise, and it is good news rather than bad, for two reasons.

The first is that a smaller, honest number is a number you can act on. You can name where those people are. You can estimate what it costs to reach one. You can tell whether a marketing channel is working, because you know roughly how big the pool is.

The second is that the arithmetic usually still works. A specific problem, held by a defined group, solved properly, at a price that reflects what the outcome is worth to a working professional, does not need a large population behind it. What it needs is that the population is real.

Treat whatever comes out as a ceiling rather than a forecast — it is the most that could happen if everything went right, and things do not all go right.

If the number comes out too small

Three moves, in order of preference.

Check the adjacent professions. Your material may translate. If you are a medical professional, does what you teach also serve physician assistants, nurses, chiropractors? If you are an engineer, does it apply outside your discipline? Sometimes the addressable market is two professions with the same problem and no shared conference.

Check the price. A small market and a high-value outcome is a perfectly good business. If what you teach changes what somebody earns or what they are allowed to do, the number of buyers required falls sharply.

Or change the problem. If the filters keep cutting the population down to nothing, the honest answer is that you picked a problem that is real, painful and rare. Go back to the list you made and take the more prevalent one.

Not the more interesting one. The more prevalent one. That is the whole difference between a business and a hobby with a sales page.
