The Small Senior Team Thesis Holds

When Kate and I started Slipway, the pitch we made to ourselves was simple: a dozen genuinely senior people, no pyramid, no account layer, no juniors learning on the client's dime. Everyone who touches the work can defend it. At the time, plenty of smart people told us it would cap our ceiling. Big briefs go to big shops, they said. You cannot staff a rebrand and a platform build and a campaign with twelve people.

Four years in, with our books just closed on the best year we have had, I want to put the actual scorecard on the table, because the thesis stopped being a bet and started being an observable market shift.

What the market did

The last eighteen months quietly rewrote agency economics. AI collapsed the production layer that big shops used to bill for. The hundred-person agency was, structurally, a machine for marking up mid-level labor. When a senior creative with good tools can do in a day what used to take a pod a week, the pyramid stops being leverage and starts being overhead.

Clients noticed before agencies did. The RFPs we see now routinely cap team size and ask for named individuals with their actual involvement percentage. Two years ago that question did not exist. Procurement departments, of all people, have become the small-team thesis's most aggressive evangelists.

Our numbers, honestly

I dislike case studies that hide the denominators, so here are ours.

• Revenue per head is up 61 percent since 2023, while headcount grew by exactly three people.
• We have lost two pitches in eighteen months to larger agencies. In both cases the deciding factor was global media buying scale, which we do not pretend to offer.
• Average engagement length is now fourteen months, up from seven. Small teams do not hand relationships off, so relationships compound.
• We are, for the first time, having serious conversations about Q4 2026 scheduling in January. Our booking horizon used to be six weeks.

The uncomfortable number: we said no to more revenue last year than we said yes to in 2022. Capacity discipline is the tax the model charges, and I will come back to that.

What the thesis does not solve

Fairness requires the other column. There are things the model genuinely cannot do.

Enormous always-on volume is one. If a client needs four hundred localized assets a month, forever, we are the wrong shape, and we say so in the first call. Global simultaneous execution is another. And there is a fragility to twelve people that a hundred-person shop does not have: one departure changes us in a way it would never change them. We manage that with equity, sabbaticals, and by being a place senior people actually want to stay, but I will not pretend the risk is zero.

The honest framing: small senior teams did not beat big shops at their game. The game changed, and the new game favors our shape.

The trap to avoid in 2026

Here is my worry for the studios adopting this model now. The thesis only works if "senior" means judgment, not just tenure. AI has made execution abundant, which means the entire value of a team like ours is concentrated in decisions: what to make, what to kill, what good looks like. A small team of senior people with average taste is just an expensive average team.

So the discipline for us this year is not growth. It is selection, on both sides of the table. Hire only people whose judgment you would defer to. Take only work where judgment is what is being purchased. The moment we take a brief that is really a volume order in disguise, the model breaks quietly, and we would deserve it.

The thesis holds. The bar it demands keeps rising. That trade still looks like the best one we ever made.
