The ICP everyone has and nobody questions

When a business isn't growing in line with ambition, somewhere in the background usually sits an Ideal Client Profile (ICP) that hasn't been seriously challenged or thoroughly revisited in a long while.

And sometimes there is no ICP at all.

This is where what I call marketing drift begins to show up, the gradual loss of alignment between market reality and marketing strategy. It often presents as a marketing issue, but is usually a function of how it is structured and constrained within the business.

Neither tends to happen by accident. It reflects how market assumptions are formed, carried forward, and rarely challenged once embedded.

So when campaigns stop landing, pipeline softens or revenue stalls, the first instinct is to question campaign quality and execution. Even though it's rarely where the real problem sits.

ICP has become one of those terms so embedded in GTM conversations that its meaning is largely assumed, yet largely misunderstood. And that's part of the problem.

Most leadership teams know they need an ICP, and many have one. But far fewer have interrogated in depth what it actually involves, what it should connect to strategically, or whether the thinking behind it is strong enough to build commercial decisions around.

In practice, what many businesses have is a document with a set of firmographic criteria - industry, company size, revenue band, geography - combined with a list of assumed pain points that felt accurate when they were written. All produced, agreed, filed and handed to the teams who need it.

Herein lies the rub. An ICP isn't a document, it's a position.

A well-thought-through ICP is a considered, evidence-based statement about where your product or service creates the most value, for whom, and under what conditions. It should reflect genuine product-market fit thinking, honest pipeline data, real customer feedback, and a clear understanding of which customers stayed, expanded and referred others - and which didn't.

It should have a clearly defined role in commercial strategy. And critically, it should have an owner. Someone accountable for keeping it current, testing its assumptions, and ensuring it is genuinely informing decisions across the business, as opposed to sitting in a folder that marketing references, sales quietly works around, and product re-creates for themselves.

Most of this is missing not because teams are careless. It is missing because the frameworks commonly used for ICP development rarely ask the deep strategic questions. Many ICP worksheets ask for the criteria, but rarely ask whether the criteria are still right. Pain points are a case in point.

The pain point problem

Pain points sit at the centre of any ICP. They connect your offer to your customer's reality and shape how messaging, campaigns and sales conversations are built. Done well, they should help identify not only who to target, but when those buyers are most likely to move.

This is because not every recognised problem creates action, and not every pain point creates enough tension to overcome inertia.

The problem is that pain points often become statements of fact rather than continuously tested assumptions. They are typically derived from sales conversations, market assumptions, product understanding, customer anecdotes and historical success patterns. Documented with confidence and then left largely untouched.

But pain isn't static: markets shift, buyer priorities evolve and commercial pressures change. A pain point that felt commercially urgent eighteen months ago may now be background noise and a new one may have emerged that isn't even reflected on the ICP.

The challenge is that if nobody is actively testing this against pipeline outcomes, customer retention, expansion behaviour and changing buying dynamics, the ICP gradually drifts out of alignment while the organisation continues operating as if it hasn't.

So who should be responsible?

Marketing, by the very nature of where they sit within the commercial organisation, is best placed to own, build and continuously evolve an effective ICP. This means drawing in feedback from across the business and staying close to changing buyer needs, motivations and priorities.

But this doesn't happen as often as it should. B2B marketing teams are usually stretched on capacity and overly indexed on delivery, which means the function best placed to own and evolve the ICP is often the one least empowered to do so. That's the authority gap in practice.

The consequence is that when campaigns underperform, the diagnosis settles on marketing execution rather than the strategic assumptions underneath it. It's one of the most common and least examined constraints on B2B marketing performance.

And no amount of persona work compensates for an ICP that was never built on the right foundations. ICP defines where you play strategically. Persona refines how you communicate once you're there. The two are related but they are not the same thing.

Does your ICP still reflect business reality?

If your ICP is already in place, the important question is not whether it looks complete or whether it is well formatted. It is whether it was built on tested foundations, whether it still reflects current market conditions, whether someone is accountable for keeping it current, and whether it is genuinely informing commercial decisions across the business.

Or whether everyone simply assumes it is.

Marketing drift rarely announces itself. It is usually a slow accumulation of misalignment, often building long before anyone recognises it for what it is. And an ICP is rarely just a targeting exercise. It is one of the clearest indicators of how well a business still understands its market, its buyers and where product-market fit genuinely exists.

When did your business last seriously question the assumptions your ICP is built on?
