Hello and welcome back, friend.
You know that slightly bittersweet feeling when something you love gets popular? The little indie band you discovered in a basement suddenly fills arenas. The tiny café where the barista knew your name becomes a sleek chain with a numbered ordering system. The warmth is replaced by efficiency, and something important quietly disappears.
That, my friend, is the scaling paradox.
Today we’re diving into one of the trickiest challenges in community building: how to grow from 100 to 10,000 members without turning the magic that made people fall in love with your group into a distant memory. I’ve watched this happen too many times, and I’ve made the mistakes myself. This episode is your blueprint for scaling without selling your soul.
Let’s talk about how to keep the intimacy even as the numbers get seriously big.
The Dunbar Dilemma Nobody Talks About
There’s a concept from anthropology called Dunbar’s Number that should probably be tattooed on every community builder’s forearm. It suggests that the human brain can only comfortably maintain about 150 stable social relationships.
Below that number? Pure magic. You know people’s projects, their kids’ names, the specific challenges keeping them up at night. The group feels like a tribe. There’s genuine connection. You can show up in the chat and people light up because they know you.
Then you cross that invisible threshold.
Suddenly you’re not running a cozy living room conversation anymore. You’re standing in a crowded stadium trying to shout personal hellos to everyone. The new member who just joined doesn’t feel like they’ve entered a community. They feel like they’ve wandered into a busy train station where everyone already seems to know each other.
I’ve seen founders react to this moment in two ways. Some double down and try to be everywhere (which leads to burnout and mediocre experiences). Others give up and accept that growth means losing the soul.
Neither approach is necessary.
There’s a third path, and it’s what I want to share with you today.
Strategy One: Stop Building One Giant Room
My personal rule of thumb: Never try to make everyone know everyone.
Instead, start thinking like an urban planner. You’re not building one massive hall. You’re building a vibrant neighborhood with smaller, meaningful pockets where people can actually connect.
I call this Deliberate Fractionalization.
Rather than one giant general chat, create smaller, nested groups based on geography, stage of business, interests, or specific challenges. When I ran a community for founders, creating an #early-stage-founders channel was genuinely game-changing. Suddenly people weren’t shouting into the void. They were talking with others who got it.
You can create:
– Regional chapters (#london, #austin, #singapore)
– Stage-specific rooms (#first-time-founder, #scaling-beyond-10m)
– Interest-based pods (#ai-enthusiasts, #parent-founders, #bootstrapper-corner)
The beauty is that people still belong to the larger community, but they have a home where they can be seen and known. The bigger group becomes the city. The smaller groups become their actual neighborhood.
Warning: Don’t create these subgroups too early. Let the community tell you what they need. When you start hearing the same questions repeatedly or noticing natural clusters forming, that’s your cue.
Strategy Two: Fire Yourself as the Hub (Yes, Really)
This is where most founders quietly sabotage their own scaling efforts.
If every new member’s experience depends on you personally welcoming them, answering their questions, and making them feel seen, you’ve built a community that cannot scale. You’ve created a brilliant bottleneck.
My unbreakable rule: The community should feel like you even when you’re not there.
The solution? Build a team of ambassadors — but choose them very, very carefully.
Here’s what I look for (and what I don’t look for). I’m not interested in the loudest or most active members. I’m looking for the most helpful. The person who answers questions before I can. The one who naturally embodies the community’s values without being asked. The member who makes others feel brilliant rather than trying to look brilliant themselves.
These ambassadors aren’t police officers. They’re hosts. Their job is to welcome new people into the smaller groups, spark meaningful conversations, notice when someone’s struggling, and protect the culture.
Think of them as your decentralized nervous system. They keep the soul of the community intact even as the body grows larger.
The first time I properly handed over the welcome experience to trained ambassadors, I was nervous. What if they didn’t do it “my way”? What actually happened was beautiful. They did it their way, which turned out to be even better. The community felt more alive, not less.
Strategy Three: Use Technology to Manufacture Serendipity
Most people use technology for broadcasting. That’s the lazy path.
The sophisticated move is to use technology to deliberately engineer intimacy and those random moments of connection that happen naturally in small groups.
Here are two of my favorite approaches:
First, Random Coffee Bots. These tools automatically pair community members for 30-minute video chats. It recreates the magic of “bumping into someone interesting” that disappears when a community gets large. Some of the most powerful relationships in my communities have been formed through these manufactured serendipitous moments.
Second, Intelligent personal invitations using the data your platform already gives you. If I see a new member has “B2B SaaS” in their profile and a fantastic thread starts in that topic, I’ll take ten seconds to send them a personal note: “Hey Sarah, saw you’re in the B2B SaaS world. This conversation is happening in the #growth channel and I thought you might have some gold to add.”
It takes almost no time but sends a powerful message: You are not just another number here. We see you.
The Bottom Line: Intimacy at Scale Is a System
Here’s what I want you to take away from this episode:
The magic doesn’t have to fade as you grow. But it also won’t happen by accident.
Intimacy at scale is a system. It requires deliberate design. It asks you to fractionalize thoughtfully, decentralize leadership wisely, and use technology as a connection tool rather than just a broadcasting megaphone.
The coffee shop doesn’t have to lose its soul when it expands. It just needs to understand what made it special in the first place and build systems to protect and distribute that specialness.
You can have both growth and genuine connection. But only if you design for both intentionally.
I’ve watched communities implement these principles and transform from feeling like “pretty good” groups into legendary movements that members talk about for years. The difference isn’t luck. It’s design.
Thanks for spending this time with me today.
Next time, in Episode 17, we’re tackling a topic near and dear to my heart: Authentic Brand Sponsorships. We’ll explore how to integrate partners and make money without ever turning your community into a cheap billboard. I can’t wait to share those lessons with you.
In the meantime, I’d love to hear from you. How are you thinking about scaling your own community? Have you hit the Dunbar wall yet? What’s working in your world?
Drop your thoughts in the comments. I read every single one.
Until next time, keep building those meaningful connections that matter.
Talk soon,
Your community-building friend
