Every executive coach I have ever met claims to help leaders with almost anything. Team dynamics, strategy, wellbeing, communication, succession, culture, the lot. It sounds generous. It is actually the fastest way to disappear. Generic leadership expertise, the kind that promises to solve any challenge for any leader, is invisible by design, and the research on how professional services firms actually win business proves it.
I used to position myself this way. Broad, flexible, whatever the client needed. Clients did not refer me for anything in particular, because there was nothing in particular to refer. A colleague would ask a friend for a good executive coach and my name would not come up, not because the work was weak, but because I was not known for one thing. That is the actual mechanism behind referrals, and it is backed by data almost no coach ever reads.
The referral research nobody in coaching bothers to read
Hinge Research Institute ran one of the largest studies of referral behaviour in professional services, surveying 1,168 participants across firms that depend on word of mouth to grow. Its Referral Marketing Study asked a direct question: what actually makes a client refer a professional services firm to someone else? The answer was not relationships in the way most coaches assume. It was something the study calls Visible Expertise, and it outweighed every other factor measured, by a wide margin.
37.3%: Visible Expertise: The single largest driver of referrals, from Hinge's study of 1,168 professional-services participants
23.1%: Good client relationships: The second largest driver, well behind demonstrated, visible expertise
17.7%: Social relationships: Referrals from professionals who are personally aware of a firm's expertise
In Hinge's own words, Visible Expertise plays the single most significant role in driving referrals, making up 37.3% of all referral driving factors. The activities that create it are named and specific: publishing educational content, speaking at conferences, and demonstrating successful projects in public. Good client relationships accounted for 23.1%, and social relationships with professionals aware of a firm's expertise accounted for 17.7%. Add those two together and Visible Expertise still edges them out on its own.
Why generic leadership expertise gets ignored
This is the part that should worry every coach with a website listing twelve service areas. Visible Expertise is not a claim. It is not a bio paragraph that promises to help leaders become their best selves across strategy, culture and performance. It is a specific, demonstrated, narrow thing a person did in public, which someone else can point to and repeat. A prospective client cannot refer a feeling. They can refer a talk they watched, an article they read, a case they heard about secondhand. Generic leadership expertise offers none of those anchors, so there is nothing for a referral to attach itself to.
This is the trap in trying to serve everyone. The wider you cast your competence, the less any single person can describe what you actually do. Ask someone to describe a generalist coach and they reach for the same three words every time: experienced, strategic, supportive. Ask them to describe a coach known for one thing, say, getting founders through the transition into running the company they built, and they can tell you exactly who to call and why. One of those descriptions gets repeated at a dinner table. The other does not.
Think of it as a signal problem, not a competence problem. A market full of coaches claiming broad, general capability is a field of dim, near-identical points of light. Nothing stands out enough to be pointed at, so nobody points. A coach with one sharp, specific claim is the single bright point against that field. It is not brighter because the work behind it is better. It is brighter because it is the only point precise enough to be seen.
Visible expertise is built, never claimed
The mechanism matters because it tells you what to actually do about it. Hinge's data does not credit vague authority or years in practice. It credits three specific, repeatable activities: publishing educational content, speaking at conferences, and demonstrating successful, specific work. None of these are personality traits. They are a body of visible output a client, or a colleague of a client, encountered before the first conversation ever happened.
- A narrow published position: Not a blog covering everything from burnout to boardroom politics. A consistent, repeated argument about one problem, written often enough that it becomes recognisable.
- A stage, even a small one: A conference talk, an internal leadership offsite, a podcast interview. The size of the room matters less than the specificity of what you were asked to speak about.
- A named body of work: Not 'I have coached executives for fifteen years' but 'I have taken eleven founders through the transition to CEO in the last three years'. A number attached to a specific problem is memorable. A number attached to nothing is not.
- A repeatable story: One client situation, told the same way often enough that people start telling it back to you. That is the moment a referral becomes possible.
Specialisation is the marketing advantage, not the compromise
Hinge's separate research into specialisation backs this up from another angle. Clients consistently value firms that specialise in their industry, and they perceive specialists as more experienced and more skilled at solving their particular problem, even when a generalist could technically do comparable work. Industry specialisation, Hinge found, is the only specialisation approach that comes with a built-in marketing advantage. Everything else, firm size, price, breadth of service, has to be argued for on its own merits. Specificity sells itself without an argument attached.
Executive coaching has no exemption from this pattern. A leader hiring a coach for a scaling founder team is not reassured by a coach who also does culture, also does wellbeing, also does conflict resolution. They are reassured by a coach who has clearly done this exact thing before, in public, more than once. Breadth reads as safety to the coach offering it. It reads as vagueness to the client trying to decide.
The cost of staying generic
I have watched this play out from both sides of the table. Coaches with genuinely deep experience across many situations struggle to get referred, because there is no single sentence a client can use to describe them. Meanwhile a newer coach with narrower experience, but a clearly stated focus, gets recommended constantly, because their name comes with a use case attached. It is not that the specialist knows more. It is that the specialist is easier to remember at the exact moment someone needs them.
This shows up hardest at the moments that matter most, like the shift a founder makes when a company they built by doing everything themselves outgrows that model entirely. A leader in that position is not looking for a generalist. They are looking for someone who has been through this specific structural change with other founders and can describe, in real detail, what breaks and what to build instead. I have written before about what that transition actually requires, and the coaches who get referred into it are never the ones offering everything. They are the ones known for that one moment.
How to choose, or become, a visible specialist
If you are hiring a coach, this research gives you a genuinely useful filter. Do not ask what a coach can help with. Ask what they are known for, and ask them to show you, not tell you. A coach with visible expertise will have something to point to: a framework they teach, a talk they have given, a specific type of leader they have taken through a specific kind of change. I set out the fuller version of this test in how to choose an executive coach who actually challenges you, but the short version is this: breadth of promise is a warning sign, not a reassurance.
If you are the coach, the fix is not to work with fewer clients. It is to be visibly known for a narrower slice of what you do, in public, consistently, until that slice is what people say when they say your name. This is the same logic behind moving away from generic coaching towards capability-based coaching built around a specific, structured discipline rather than a loose promise to help. It is also why I describe my own work as a structural discipline rather than a service list. I wrote about what that actually means in what a leadership capability architect actually does, because the title itself is a form of visible expertise. It tells a client exactly what problem I am built to solve, before we have spoken once.
This is also the discipline behind CapabilityAI and the engagements I run through Work With Me: both are built around a specific, named discipline of leadership capability, not a general promise to help with whatever comes up.
Visibility and generalism cannot both be true at once. The wider your claimed competence, the less specific anything you say can be, and the less specific it is, the less anyone can repeat it to someone else. It is not that broad expertise does not exist, it is that broad expertise does not travel. Referrals travel on specificity. Build the narrow thing people can actually describe, and the broader reputation follows on its own, not the other way round. Keep waiting for word of mouth to arrive on its own, without ever giving anyone a specific reason to say your name, and it simply will not come. That is not bad luck. It is the predictable result of a positioning choice, and it is entirely within your control to change.
A practical reading path
The useful test for why generic leadership expertise fails to win trust is whether a leader can make a better decision in the work that already exists. Start with one live case, write down the judgement that was used and compare it with the result that followed. Then ask what the team would do when the same pressure appears next month. That question keeps the article close to practice rather than turning it into another list of principles. It also gives a sponsor something concrete to challenge: the owner, the evidence, the trade-off and the point at which the plan should change.
A second check is transfer. If the idea in this article depends on one senior person, a special workshop or a project team standing beside the work, it has not yet become an organisational capability. Try the decision with a new manager or an unfamiliar case. Note what remains clear, what needs coaching and what still relies on personal memory. That small test gives why generic leadership expertise fails to win trust a boundary. It says what the approach can support now, what must be tested next and which claim should not be made until the evidence is stronger.
Where this fits in the wider work
This topic sits beside three decisions that often get separated in practice. Read the human and AI decision ladder; why digital transformation programmes fail and the leadership fix; lead organisational transformation successfully. The comparison is useful because it keeps the argument in this article specific: which decision is changing, who owns it and what evidence would show that the change has travelled into everyday work? Use the linked pieces as contrasts, not as a substitute for the judgement required here.
