Is your positioning based on evidence or internal assumptions? Learn what to challenge.

Most companies have a view of why customers choose them.
“We win because of our expertise.”
“Customers value our flexibility.”
“Our strongest differentiator is our technology.”
“Price is why we lose deals.”
“Our ideal customer is a large enterprise.”
These statements may all be true.
But there is another possibility: they have been repeated internally so often that they have started to sound like facts.
Strong B2B positioning is neither what the company believes nor simply what customers say. It is a strategic choice grounded in evidence.
The harder part is knowing which parts of the current positioning are actually supported by evidence and which are assumptions that have gradually become accepted as facts.
Positioning often starts with what the company already believes
This is understandable.
Founders know why they built the company. Sales hears objections every day. Product knows the strengths of the offering. Marketing sees competitors and customer feedback. Leadership has a view of where the business should grow.
All of that is useful input.
The problem starts when internal knowledge is treated as the same thing as external evidence.
Sales might say customers buy because of expertise.
But if customers see expertise as something they expect from every credible supplier, it may not be what drives the decision.
Marketing may see three companies as the main competitors.
But customers might be comparing the offering with an internal process, an existing supplier or doing nothing at all.
The company may talk about flexibility as a differentiator.
Customers might appreciate it without it ever affecting who they choose.
None of these internal views are necessarily wrong.
I find one question particularly useful:
What is this actually based on?
Evidence and interpretation are not the same thing
A company can know its customers well and still carry assumptions that have not been questioned for years.
One distinction I find useful is separating evidence from what we make of it.
Evidence: information we can trace back to an identifiable source — for example customer interviews, behaviour, deal data or market research.
Interpretation: what we think that evidence means.
Assumption: something we are currently treating as true without enough evidence.
Unknown: something we simply do not know yet.
A hypothesis is an assumption we have decided to test.
The distinction matters.
A customer saying “the implementation felt safe” is evidence.
Concluding that “our implementation model is our strongest differentiator” is an interpretation.
It may turn out to be right. But the customer did not actually say that.
This is one reason internal discussions about customers can get confusing. Evidence, interpretation and assumption gradually become mixed together until nobody quite remembers where the original idea came from.
A positioning workshop cannot create customer truth
Workshops can be extremely useful.
They bring different perspectives together. They surface disagreement. They help people make choices. They can also reveal what still needs to be understood.
But a room full of knowledgeable people is still a room full of internal perspectives.
If nobody has checked what customers actually compare, value, worry about or use to make a decision, the workshop may simply organise existing assumptions more neatly.
That does not mean every positioning project needs months of research.
The evidence may already exist in customer interviews, win/loss notes, sales calls, CRM records, customer success conversations or previous research.
Sometimes a few well-chosen conversations are enough to challenge an assumption that has shaped the company’s story for years.
How much research you need depends on the decision and how much is at stake. What matters is whether you have enough relevant evidence to challenge or support the choices you are making.
But customers cannot give you your positioning either
It is also possible to go too far the other way and expect customers to tell you what your positioning should be.
They cannot.
Customers can tell you about their situation, how they made a decision, which alternatives they considered, what mattered, what worried them and what they experienced.
That evidence is extremely useful.
But the company still has to make the strategic choices.
A customer may value something you do well, but that does not automatically mean you should build your position around it.
Perhaps competitors can make the same claim.
Perhaps it matters only in a very specific buying situation.
Perhaps it does not support where the business wants to grow.
Perhaps you cannot deliver or prove it consistently.
Evidence informs positioning. It does not make the positioning decision for you.
Or put another way:
Positioning is a business choice informed by evidence not a customer vote.
Customer evidence also has to be considered alongside what is happening in the market, what the offering can actually deliver and what makes sense for the business.
I wrote more about those connected realities in Clearer marketing starts by understanding reality.
How to test the assumptions behind your B2B positioning
You do not need to turn this into a large research exercise.
Start by looking at the statements your current positioning depends on and ask where each one comes from.
For example:
We know who our best-fit customers are. Based on what?
We know what triggers them to look for a solution. Based on what?
We know which alternatives they consider. Based on what?
We know why they choose us. Based on what?
We know which parts of our offering they value most. Based on what?
We know what makes us meaningfully different. Based on what?
We know which claims customers believe. Based on what?
You do not need perfect evidence behind every answer.
But it helps to know where you are on fairly solid ground and where you are still making a bet.
That becomes especially important when the market changes, a new offering is launched, the company enters a new segment or the old story simply stops working as well as it used to.
Better positioning starts with better questions
Positioning will always contain judgement.
There is no customer interview that will hand you the perfect position. No dataset removes the need to choose. No workshop makes uncertainty disappear.
But there is a big difference between making a strategic choice when you know what is evidence, what is interpretation, what is assumption and what is still unknown and making that choice without knowing the difference.
Evidence does not give you the positioning. It gives you a better basis for choosing one.
And sometimes the most useful first step is not rewriting the positioning at all.
It is asking:
What do we believe to be true and how much of it do we actually know?
