Why we don't take on more than eight engagements at a time

Sheppard caps the number of active engagements at any one time. We don't publish the exact number on every page because it shifts slightly with the mix of work (an audit is lighter than a full execution engagement), but the practical ceiling is around eight active operators across the practice. We turn away more business than we take. On purpose.

This is the design decision we're least willing to compromise on. It's the part of the model that makes every other part work. Without it, the operating model collapses into a traditional agency, no matter what we say about how we're different.

The math

A senior marketing operator can do real work on a small number of engagements at once. Not nominal work, where the engagement is on the list but the actual attention is sporadic. Real work, where the operator can read the dashboards before the operating partner does, know what changed week-over-week without checking, and have a defensible opinion on every meaningful channel decision.

Our calibration is that one senior operator can carry two to three full execution engagements at full depth, or four to six audit-and-advisory engagements at the lighter touch those require. Cross the line and the work becomes reactive: emails answered without the underlying context, recommendations made from the dashboard's framing instead of from the operator's, decisions deferred to scheduled meetings instead of made in the moment they come up.

That's not a hypothetical. It's what happens to senior people at every agency that grows past the limit and keeps the same staffing model. The senior person stops being able to operate; they become an account manager for the work juniors are doing on their behalf. The operator paying for senior judgment gets junior decisions with a senior signature.

The cap is the only thing that prevents it

Most agencies that say they keep senior people on accounts mean it sincerely when they say it. They don't keep doing it after they grow past the math. The pull of taking the next engagement is constant. The pressure to staff growth with juniors is constant. The capacity to maintain the discipline is finite. Within a year of growing past the cap, the practice looks like every other agency, even though the founders genuinely intended otherwise.

Capping engagements is the only mechanism we've seen that holds. It forces the next conversation, every time: do we take this one and drop another, or do we say no. Both answers are honest; growth-without-the-cap is the dishonest answer.

What this costs us

We turn away qualified engagements regularly. Sometimes excellent ones — operators we'd genuinely like to work with, deals we'd genuinely like to be part of, businesses where we know we'd do good work. We say no because the math doesn't allow yes without breaking the model.

It also costs revenue. A traditional agency operating at the same staff size at, say, twenty engagements would generate materially more topline than Sheppard at eight. We've made a calculation that quality of work and reputation over a decade is worth more than top-line growth in any given quarter. That calculation is right for our model. It's not right for every model.

What it costs you

If you reach out and we're at capacity, you'll hear that honestly. We'll point you toward a few practices we trust if your timeline can't wait, and we'll mark the calendar for when we're likely to have an opening. Some operators wait. Some don't, which is fine.

The Marketing Stack Audit (3 to 4 weeks, the entry point for almost every engagement) is bounded enough that we can usually find a slot for one inside a quarter. Full execution engagements are the ones with longer waits. If you have a defined deadline (an LOI closing, a 100-day post-close window, a pre-exit prep schedule), tell us in the first message and we'll work backward from there.

Why this matters more than it sounds

If you're evaluating a marketing partner and they don't have a capacity cap, look closer at how they staff your account. Ask who specifically is on the work. Ask the cadence of senior attention. Ask how many other engagements that senior person is also responsible for this week.

The answers tell you more than the pitch deck does. An agency that says it provides senior attention but staffs accounts with juniors isn't lying; it's describing the model it wants to be operating, not the one it actually operates. The honest version of that is: we're growing, we have to staff the growth somehow, here's who's actually on your account.

We're not arguing every operator should hire a capped-capacity practice. There are good reasons to hire larger agencies with bench depth and resources we don't have. We're arguing that the staffing model is the most important question to ask in any agency evaluation, and that the answer mostly comes down to capacity discipline.

Sheppard's answer is the cap. Eight engagements, senior people on every one, no growth past the line without restructuring the practice. That's the design decision the rest of the practice rides on.
