At 20 People, Your Culture Is Whoever's in the Room

Ask a founder what makes their company special and you’ll get twenty minutes: the way people jump in to help before they’re asked, the bar they hold on the work, the meetings that somehow stay honest. Ask that same founder to write it down, clearly enough that a recruiter who’s never met them could screen for it, and the room goes quiet.

That quiet pause is the whole problem. It’s the sound of a culture everyone can feel and no one has shaped. And it’s fine, right up until you start growing fast.

Think about a young plant. When it’s small, it more or less holds itself up. You’re right there beside it, and a hand or a single stake is enough to keep it heading the right direction. That’s culture at 20 people. It lives in proximity: new folks learn how things are done by sitting next to the people who’ve always done them, and the few who set the tone are close enough to catch a stray shoot before it takes over.

Then the thing grows. And a vigorous plant with nothing to climb doesn’t grow up; it sprawls. It runs along the ground, tangles into itself, reaches for whatever happens to be nearest, and lets a few aggressive shoots swallow the rest. That’s what culture does when you start hiring ten people a month and the room stops working as a teacher. The new folks don’t sit next to the founders; they sit next to other new folks. The culture stops growing toward anything in particular and starts growing toward whatever’s nearest: the average of whoever you happened to hire last quarter. Nobody decided to change it. It just sprawled, because that’s what growth does without structure.

And the misfires are expensive in a way the spreadsheet never quite captures. When Leadership IQ tracked 20,000 new hires, 46% of them failed inside 18 months, and 89% of the time the reason was attitude, not skill: coachability, temperament, emotional intelligence, motivation. Only 11% failed for lack of technical ability (Leadership IQ). Almost nobody flames out because they couldn't do the work. They flame out because they didn't fit, and fit is exactly the thing you can't screen for when you've never shaped what the thing is supposed to grow into.

This is where most leaders take a wrong turn. They watch the sprawl, they get nervous, and they reach for a cage. Rules for everything. Approvals on top of approvals. A values statement enforced like a dress code. They try to force the plant into a shape, and it works, in the way a topiary works. You get something controlled and uniform and a little lifeless. You've traded the tangle for a cookie-cutter, and in the trade you've killed the vigor that made the thing worth growing in the first place. People stop creating and start complying. That isn't culture. It's taxidermy.

The answer to sprawl isn't a cage. It's a trellis.

A trellis doesn't dictate where a single leaf goes. It gives the plant something to climb: direction, shape, light, air. Then it lets the plant grow its own way within that structure. Two vines on the same trellis will never be identical; they'll reach and branch and produce in their own fashion. But they'll grow in the same direction, hold a recognizable shape, and none of them will end up face-down in the dirt. That's the culture you're actually after: a structure clear enough to keep everyone growing the same way, open enough that people still get to create.

So what's the trellis made of? Not "integrity, excellence, teamwork" on a lobby wall; that's a garden ornament. It's decorative and it holds nothing up. A trellis is built from behaviors specific enough to actually guide growth. Not "we value candor" but "we say the hard thing in the room, not in the parking lot afterward." Not "we're customer-obsessed" but "we'll kill our own favorite idea the moment the customer tells us it's wrong." Specific enough to give the growth its shape, open enough that everyone finds their own way to live it. The test is simple: could you hand it to someone who's never met you, and would they grow in roughly the same direction you would?

And a trellis only does its job if you build it on purpose and keep training the new growth onto it. You tie in the new shoots. You guide the tendrils while they're young and pliable. You do it again every season, because the plant keeps growing and the growth keeps reaching for the nearest thing. Left completely alone, even a healthy plant on a good trellis will throw runners into the dirt. So the work isn't writing the values down once and framing them. It's building the structure into how you actually hire, onboard, and promote, training every new season of growth onto the same frame.

So the honest question is harder than it sounds: could you build the trellis? Could you name the few things clearly enough that a new person, or a hundred of them, would grow along them without you standing there holding each stem? Most leaders can't. Not because they don't have a culture, but because it always just… worked, and they never had to give it a shape.

It worked because you were small. Growth is what turns "it just works" into a tangle. The companies that keep their culture through scale aren't the ones who caged it, and they aren't the ones who let it run wild. They're the ones who built the trellis while they still knew what they were growing.
