Growth Consulting for Agencies and Consulting Firms
Businesses that sell advice are unusually bad at taking it. Agencies and consulting firms are typically excellent at diagnosing a client's growth problem and reliably poor at diagnosing their own — not through hypocrisy, but because the same capacity that would do the diagnosis is always billable elsewhere, and because a business full of experts finds it uncomfortable to be the one that needs help.
The uncomfortable pattern
Firms that sell advice are frequently the worst-run businesses in their own client roster. This is well known inside the category and rarely examined.
The mechanism is not hypocrisy. It is that diagnostic capacity in a services firm is the same capacity that bills, so the firm's own problems are always assessed with whatever is left over — which is nothing, in a good year. There is also a social cost: a business of experts finds it genuinely uncomfortable to conclude that it needs an outside read, in a way that a manufacturer does not.
So the work does not happen, and the firm carries problems it would diagnose in a client within two weeks.
Where the constraint usually sits
Client concentration, which is a market constraint wearing an operations costume
When a large share of revenue sits with two or three clients, the firm is not fully independent. Pricing power is limited, hard conversations get avoided, and capacity planning is hostage to someone else's budget cycle. Most importantly, the firm cannot decline work it should decline, which is the foundation of every strong service business.
This gets treated as a sales problem and it is a market one: the firm has not built a repeatable route to demand outside its existing relationships, so concentration is not a choice it made but the residue of never having had an alternative.
Delivery cost that nobody measures
Agencies price by project, retainer, or value, and deliver by hours. When the two are not connected in any report, the firm cannot say which work is profitable. It grows the work that is easiest to sell and pleasant to do, which correlates only loosely with the work that pays.
Scope creep is the accelerant. An extra round of revisions is small; forty of them is the year's profit. Most agencies have a change-order process. Far fewer use it consistently, because invoking it feels adversarial and nobody can see the cumulative cost of not invoking it.
The owner is still the product
In many firms the owner is the reason clients buy — the credibility, the judgment, the relationship. That is a genuine asset and a hard ceiling. It caps growth at the owner's available attention, and it caps enterprise value, because a firm that cannot operate without one person is difficult to sell.
Why the standard advice misfires
The agency world has a well-developed prescription: niche down, raise prices, productize, build a content engine, fire your worst clients. Each is sound in the right circumstance. All of it is dispensed without diagnosis.
Niching helps a firm whose constraint is positioning, and does nothing for a firm that loses money on delivery — it simply reduces the pool of replacements for work it cannot afford to lose. Raising prices helps a firm with strong delivery and weak pricing confidence, and accelerates churn in a firm whose delivery is genuinely inconsistent. Productizing helps a firm doing the same engagement repeatedly, and produces a rigid offering nobody wants in a firm whose work is genuinely bespoke.
This is the Law of Constraints again: improving anything except the binding constraint creates activity. In agencies the activity is unusually convincing, because it is the same advice the firm gives its own clients and therefore feels obviously correct.
A read worth running on yourself
- What share of revenue and of margin comes from your top three clients? What happens to the business if the largest leaves in ninety days?
- For your last ten projects: hours actually worked against hours assumed at pricing. What is the spread?
- How much new business last year came from sources other than the owner's network and referrals?
- Which service line is most profitable? If answering takes more than an afternoon, that is your finding.
- How many clients are you retaining that you would not sign today?
That last one is the most diagnostic question on the list, and the one firms most often skip. A book full of clients you would not sign today is a book that will not support the business you say you want to build.
What we would recommend first
Margin by project type, built from the time system and the invoicing system, which few agencies have joined. Then one decision with it: which service line gets the next increment of business development attention.
That decision is the fork. Made on revenue and enthusiasm, firms grow their most saleable work. Made on margin, they grow the work that funds the business — and those are rarely the same, which is precisely why the number is worth building before the strategy conversation rather than after it.
On hiring an outside partner when you are the outside partner
Worth naming directly, because it is the actual objection. Firms in this category resist outside help partly because it feels like an admission, and partly because they have watched enough consultants work to be skeptical of the genre.
The reasonable version of that skepticism is a question about method. So ask for the method. Ask what would be examined before anything is recommended, what happens if the answer is something the partner does not sell, and what a recommendation will actually contain. We publish ours in full, with a complete worked example, specifically so it can be judged before anyone is hired.
The advantage an outside read has over your own is not intelligence. It is that it is not also billable somewhere else.
Common questions
Why do agencies stop growing at a certain size?
Usually because the model that worked early stops working and nothing replaces it. Early growth comes from the owner's network and reputation, which is real but finite. When it is exhausted, the business needs a repeatable way to generate demand and has never built one — and the people who would build it are fully committed to delivery.
What is the most common financial problem in agencies?
Client concentration paired with no visibility into project-level margin. When a large share of revenue sits with a small number of clients, the business is not really independent — it is a department of its largest account with extra steps. And when margin is only visible at the company level, the firm cannot tell which work is worth defending.
Should an agency niche down to grow?
It frequently helps, but only if the diagnosis says positioning is the constraint. Niching is prescribed almost universally in agency circles, which means it is often applied to businesses whose actual problem is delivery cost, scope discipline, or client concentration. Narrowing your market does not fix a business that loses money on delivery — it makes the same losses harder to replace.
How do agencies fix scope creep?
By making it visible before making it a policy. Most agencies already have a change-order process that nobody uses, because using it feels adversarial and nobody can see what not using it costs. Measure hours against the scoped assumption per project for one quarter; the aggregate number usually makes the policy enforce itself.
