What you get, and what you give up
With a lone consultant you get specialist depth, but everything rests on one person's time, calendar and blind spots. The depth is there, the whole rarely is. With a traditional agency you get breadth and continuity, but the senior who won the meeting disappears and someone still learning takes over the ongoing work. On top of that you pay for the size of the office, not only for the work.
Both paths force a compromise. It isn't a failure in either of them, it's built into the shape.
A third model
You get senior specialists matched per assignment, without paying for an agency's fixed costs. We are not a traditional agency, but a network of specialists where one strategist holds the whole and the right person steps in where they fit. We are the filter between you and the specialists, so you don't have to guess who you need, or when.
An experienced specialist does in an hour what a junior does in four, and without the rounds of correction that follow a guess. You should never pay for anyone's learning curve, and you always know who does the work.
Why the choice exists at all
The question comes up because the industry rarely offers anything between the two extremes: the expensive agency with overhead or the lone consultant without continuity. So the label matters more than the substance. But the label isn't what decides the result.
The question isn't consultant or agency. It's who holds the pen, and how you measure what they do.
It's the same logic behind our price cap and our view on seniority: you should pay for effect, not for form. If you want to know what it would look like for you specifically, ask us.
