Nano. Micro. Small. Here's What I Actually Mean
A framework for understanding the three tiers of small agency — and why the distinctions matter more now than ever.
I was in a roundtable recently, talking about micro agencies, and someone stopped me. What do you mean by micro agency exactly? And I realized I had gotten ahead of myself.
I’ve been writing about nano agencies. I’ve been talking about micro agencies in my coaching work. I’ve been using these words like they’re common language. But I haven’t actually stopped to define them, or explain why I think the distinctions matter.
So let’s go back to the foundation.
Three tiers
A nano agency is a solo or near-solo operation. One or two core people, working with subcontractors when the work calls for it. The owner is typically both the strategist and the doer. Lean by design.
A micro agency is the next evolution. Under five full-time people, typically the owner plus a small core team, still working with a flexible network of subcontractors. More capacity, more structure, more ability to take on work that compounds.
A small agency is five or more full-time people. A dedicated team with defined roles, more delivery capacity, and higher overhead to match.
Why this framework matters now
I’m not introducing this framework for the sake of labels.
I’m introducing it because I think all three tiers have a genuine structural advantage in the market we’re in right now. Most of the people sitting inside these businesses don’t fully see it yet.
We may be in an economic dip right now. But what comes out the other side of a dip doesn’t reward the agencies that tried to be everything. It rewards the ones that knew exactly what they were for.
Large agencies carry large overhead.
They have layers between the client and the people thinking about their business. When budgets tighten and clients want accountability, those layers become a liability.
The agencies in this framework don’t have that problem. There are no layers. The client gets direct access to the people thinking about their business. That’s not a consolation prize for being small. That’s a structural advantage.
Then there’s AI.
The common assumption is that AI favors larger operators with more resources to deploy it. The opposite is true. AI compresses execution. It levels the playing field on output.
What it cannot do is provide judgment, domain expertise, or the kind of contextual knowledge that comes from years inside a specific industry or service area.
When everyone has access to the same execution tools, differentiation moves entirely to those things. And those things live inside small focused teams, not inside large ones stretched across too many categories.
AI doesn’t shrink the opportunity for agencies in this framework. It expands it.
What powers each tier
Size alone doesn’t create the advantage.
Plenty of nano, micro, and small agencies exist right now, competing on price, hard to find, hard to refer, hard to grow. Being small doesn’t protect you from that.
What does? Specialization. A specific industry, a specific service, or ideally both. That focus is what turns the structural advantage of being small into something a client can actually find, understand, and trust.
At the nano level, specialization pairs with agility. You can move fast, pivot when needed, and go deep on exactly what your client needs without the drag of a larger operation.
At the micro level, specialization pairs with process. You have enough structure to deliver consistently, repeatably, and at a level that compounds over time.
At the small agency level, specialization pairs with capacity. You can take on more without losing the niche. That combination is hard for anyone to compete with.
The tier you’re in shapes what specialization is paired with. But specialization is the thing that makes any of it work.
Where you sit in the framework
I work with owners across all three tiers.
And the most common thing I see, regardless of size, is that people underestimate what they’ve built.
They describe themselves as freelancers when they have a team. They say it’s just me and a few people when they have a process, a client roster, and real results. They shrink from the word agency because it feels too big, too corporate, too removed from the relationships they’ve built.
But this framework isn’t about size as status. It’s about understanding what you actually have and building from that honestly.
If you’re somewhere in this framework right now. The question isn’t whether you belong here.
The question is whether you know where you sit, and whether you’re building with that clarity.
