Operations
The constraint is rarely where you think it is
Most leadership teams can name their problem. Far fewer can size it. The gap between those two things is where consultancy money is usually wasted.

When a founder-led business stalls, the explanation offered is almost always the same: we need more leads. It is the most visible symptom and the easiest one to buy a solution for. It is also, in our experience, the correct diagnosis less than half the time.
The businesses we see between £2m and £25m turnover are far more often constrained by conversion discipline, delivery capacity, pricing, or the fact that every material decision still routes through one person. Adding demand to any of those situations makes the underlying problem worse, not better — it simply arrives faster.
The discipline that changes outcomes is quantification. Not 'our quoting is slow', but 'quoting takes an average of nine days, we lose 31 per cent of opportunities that wait longer than five, and that is £480,000 of annual revenue'. Once a constraint has a number attached, the argument about what to do next tends to resolve itself.
This is why we insist on paid discovery before any complex proposal. A free proposal is a guess dressed as a plan. It is also, structurally, a document designed to sell work rather than to find the truth — and the two objectives are not always aligned.

Across the founder-led businesses Nuub has diagnosed, the constraint named by the leadership team is frequently not the one limiting the result. This is practitioner observation, not a measured population statistic.
