There’s a version of this story that plays out in membership communities all the time.

A founder launches. They hustle hard — posting, emailing, showing up everywhere — and they hit 100 members. They celebrate. They take a breath.

And then they look around at their community and realize it’s completely silent.

Nobody’s posting. Nobody’s responding to prompts. The calls have five attendees on a good day. The founder is the most active person in a community she built for other people.

She didn’t fail to grow. She failed to grow with intention.

And almost always, the problem traces back to the very beginning — to who the first members were and whether they were the right ones.

The founding member phenomenon

Your first 10 members are not just your first customers. They are your culture architects.

They establish what normal looks like inside your community. They model the behavior that every member who joins after them will see, read, and unconsciously calibrate to.

Think about walking into a restaurant for the first time. Within thirty seconds, you’ve taken in whether people are dressed up or casual, whether it’s loud or quiet, whether conversations are lingering or quick. You haven’t been told how to act. You just read the room.

Your community works exactly the same way.

When a new member joins and looks around at the existing conversations — the kinds of questions being asked, the depth of what’s being shared, the level of generosity or engagement on display — they read that room. And they act accordingly.

If your founding members are passive lurkers who joined because they got a deal and figured they’d see, that’s the room new members are walking into.

If your founding members are misaligned — too early in their journey, too far ahead, or simply not quite your people — that’s the energy that gets baked into your community before you even realize it’s happening.

And once community culture is set, it is very hard to change. Not impossible. But a significantly heavier lift than simply getting it right at the start.

The myth that costs community builders the most

The “fill the seats, then fix the vibe” approach is one of the most common — and expensive — mistakes I see community builders make.

Get people in. Get the numbers up. Worry about engagement later.

The logic makes sense on the surface, especially when you’re staring at an empty community and feeling vulnerable about it. But here’s what that approach misses: you can’t fix the vibe after the culture has calcified.

Think of it like pouring concrete. When a community is brand new, the culture is still wet and workable. You can shape it, press things into it, build intentionally. But once it sets, you’re not shaping anymore. You’re chipping. And chipping at a set culture is exhausting, slow, and rarely fully effective.

The founders who “fill it then fix it” end up spending months trying to re-engage a community that was set up from the beginning to be disengaged. They’re fighting a culture they accidentally created.

The founders who are intentional from the start spend that same time growing something that already has momentum behind it.

Your founding members are already in your world

Here’s the part that often surprises people: you don’t have to go find your founding members. You probably already know who they are.

They’re the people who respond to your emails. Who comment thoughtfully on your content. Who have worked with you before and gotten real results. Who reach out to tell you something you said resonated. Who are already talking to you about the exact problems your community is designed to solve.

The right founding members are almost never strangers. They are warm leads, existing clients, and engaged followers — people who already trust you and already see the value in what you’re building.

When you’re preparing to open your community, don’t start with a discount code blasted to your entire list. Start with a short list of people you’d genuinely be excited to have in the room on day one. Reach out personally. Tell them you built this with people like them in mind.

That outreach alone will produce a different kind of member than a generic launch announcement ever will.

The Founding 10 Filter

Before letting someone join in that early founding window, run them through three questions.

Do they have a problem your community is designed to solve?

Not a vague interest in the topic — an actual, active problem they’re trying to work through right now. People with a real problem are motivated to engage. They show up because they need something, and your community is where they’re going to find it.

Are they at the right stage for your community?

This is about fit, not gatekeeping. If they’re too early in their journey, the nuance of your conversations won’t land. If they’re too advanced, they’ll feel like they’re waiting for everyone else to catch up. Either way, it’s not a great experience for them — or for your other members.

Have they given you any signal that they’ll actually show up?

Have they engaged with your content before? Do they reply to emails? Did they ask a thoughtful question when they expressed interest? Members who give signals of engagement before joining almost always continue that behavior after joining.

And one more worth asking yourself: is this someone whose presence will add something to the room? Curious, generous, inclined to engage? The quality of a community is just the sum of its conversations. The people who raise the quality of every conversation they touch are the ones worth going out of your way to invite.

What happens when you get it right

When your founding cohort is genuinely well-matched, a few things happen almost immediately.

The energy becomes self-sustaining. You don’t have to force conversations into existence — they happen because people have real reasons to show up.

The community starts to co-create itself. Founding members tell you what they need. They create informal rituals nobody planned. Your community develops a personality that comes from the people in it, not from you trying to manufacture it.

And your founding members become your best marketers. Not because you asked them to — because when people are genuinely getting value from something, they talk about it. That word of mouth compounds in ways that no launch strategy can replicate.

On starting small

I know the fear underneath all of this. If you’re too selective, nobody will join. If you start too small, you’ll never build momentum. Ten members just doesn’t feel like enough.

Here’s what I’d push back on.

A tight, engaged community of 10 people is more powerful — not just in experience, but in business terms — than a sprawling, disengaged community of 100.

Those 10 engaged people are telling their friends, giving you testimonials, creating the proof of concept you need to grow. The 100 disengaged people are quietly churning, or staying but adding nothing to the culture.

Numbers feel like progress. Engaged, aligned members are actual progress.

And the way you treat your founding members signals something important to them. When you reach out personally, when you tell them you built this with people like them in mind, that makes people feel chosen. Chosen members show up differently. They stick around differently. They advocate differently.

The compounding effect of getting your first 10 right is real — and it starts with something as simple as being intentional.

You can always grow your numbers. But you can’t un-set a culture.

Get your first 10 right, and everything that comes after gets easier.

Your first 10 aren’t just the beginning. For a while, they are the community. And eventually, when you have a hundred engaged members showing up and bringing their colleagues along, it’s going to be because of those first 10 who made the room worth being in.

That’s the thing worth building toward.
