Closeness Circles
A Trust-Based Communication Framework for Communities
Closeness Circles organises your community into layers of trust — Core, Inner Circle, Network, Crowd — so people move closer at their own pace through contribution.
Define: Closeness Circles
Closeness Circles is a community framework that organises the people in your community into concentric layers of trust — Core, Inner Circle, Network, and Crowd — each with its own cadence and depth of communication, so that members can move closer to your centre at their own pace through genuine contribution.
Closeness Defines Trust
There are things you tell your family before anyone else. There are things you tell your closest friends that you would never post publicly. Layers of communication are not something we invent for organisations — they are how human relationships already work.
Our relationships grow out of repeated interaction, which builds familiarity, and familiarity is what makes trust possible.
“The way to make people trust-worthy is to trust them.”
Why do communities need layers of communication?
Communities need layers of communication because trust is not evenly distributed, and pretending it is will break both ends of your community. Speak to everyone as though they were your closest collaborator and the intimacy stops meaning anything. Speak to everyone as though they were a stranger and the people who have given the most get nothing back for it.
Layers let you match the depth of what you share to the depth of the relationship you actually have.
Your responsibility as a community builder is to build communication systems that create and maintain trust — and to hand people the tools that let them contribute to the community's growth.A well-designed system does two things at once:
It strengthens the bonds with the people already closest to you.
It shows newcomers how to step closer to your core, at their own pace.
The purpose is not to put people in bubbles.
It is to organise your communication so that closeness becomes something a person can move through, rather than something they either have or don't.
What are the layers in the Closeness Circles?
The essential layers in the Closeness Circles are (from inside out):
Core
Inner Circle
Network
Crowd
The Core is the small group at the centre — the people whose contribution is essential and who hear things first. The Inner Circle is the next layer out: committed contributors, ambassadors, and long-term collaborators. The Network is the wider body of engaged members.
The Crowd sits beyond the circles altogether — the broader audience that is aware of you but not yet inside.
The further inward you go, the deeper you go into the community. Each layer implies its own communication scheme: a different cadence, a different level of detail, a different degree of candour about what is going well and what isn't.
A simple test for whether you have your layers right: it should feel obviously wrong to share something with your broader network that your own team hasn't heard yet. If that doesn't feel wrong, your circles aren't real yet.
What the layers look like for a business community
Core — your team, collaborators, and top contributors
Inner Circle — key partners, fans, and brand ambassadors
Network — active users
Crowd — subscribers, and your broader public network
How many Closeness Circles should a community have?
Three layers is the minimum, and for most communities it is also enough. Three is the smallest number that keeps a community in balance. With only two layers you create an inside and an outside — some people posturing for status they don't hold, others feeling shut out — and that polarity erodes the safety a community needs in order to exist at all.
A third layer breaks the binary. From there you can add layers outward as your community's complexity genuinely requires it.
Resist the urge to add more than you need. Every layer you draw is a promise to communicate differently with the people in it, and an unkept layer is worse than no layer.
How do people move closer to the core?
People move closer to the core through wholehearted contribution. The most reliable way into your inner circles is not tenure, proximity, or charm — it is having given something real to the community and to the other people in it. Those who feel the strongest sense of belonging tend to develop a sense of ownership, and ownership is what makes someone raise their hand to help the community grow.
Time helps, but it is not the only variable. Three others matter as much (as on Engineering Serendipity).
Frequency — how often someone is in the room. More encounters, more chances for a real relationship to form.
Density — how relevant the encounter is to them, and how well the space is designed for actual conversation.
Catalysts — anything that accelerates a bond. Inherited trust is the strongest one: you build ties with a close friend's friend far faster than with a stranger, because your friend has already vouched.
Which is why some people become close very quickly regardless of how long they've been around. They arrive contributing. They are the people who give before taking (abundance), who genuinely believe we rise by lifting others (humility), and who act on both with sincerity (authenticity). They are living your core values before anyone has told them what those values are.
Should members be able to see the Closeness Circles?
It depends on what your community is for, and it is a real decision rather than a default.
The structure is usually clear to someone already near the core and often undisclosed to those in the outer layers — because naming the hierarchy can produce exactly the negative group dynamics the framework exists to prevent, with newcomers reading the map and concluding they're on the outside of it.
But transparency has real uses. Some communities publish the path deliberately, advertising what an Ambassador does and how someone becomes one, and leverage it as an honest invitation rather than a ranking.
The line to hold is this: people in the outer layers should have clarity about the kinds of contribution that bring them closer, and they should never be made to feel that staying where they are is a failure. There will always be different levels of participation appropriate to different people and different seasons of life. Your job is to help each person find the level of involvement where they feel most at home — not only to move everyone inward.
Putting the framework to work
How do I draw my own Closeness Circles?
Start by listing everyone who touches your community, then sort them by what they have given rather than by how well you know them. Contribution is the sorting variable, not familiarity — it is the difference between a community structure and a friendship group with a logo on it.
Then, for each layer, answer three questions:
Cadence — how often do these people hear from you?
Depth — what do they hear that the next layer out does not?
Channel — where does that communication actually happen?
Finally, run the cascade test on a real piece of news. Write down, in order, who finds out and how. If your Crowd would learn something before your Core does, you have a design problem — and you now know exactly where it is.
Where does the Closeness Circles framework come from?
The Closeness Circles framework is adapted from the work of Robin Dunbar, the anthropologist and psychologist behind the widely cited idea that a person's network cannot exceed 150 people. That figure is a simplification of what Dunbar actually meant: our direct contact group sits somewhere between one hundred and two hundred people depending on how social we are — the people you'd invite to a large party.
Dunbar's network has layers of its own. The closest five are the most essential people in your life, family included. Beyond them sit roughly fifteen you'd call your closest friends. Up to fifty are the people you'd invite to a casual party. Fifty to 150 is the rest of your friend group. Beyond that, groups can grow to around five hundred acquaintances and out to 1,500 in your broader network.
I built the Closeness Circles from a simplified version of that theory. At the centre, your core people. In the second layer, your inner circle. In the third and outermost, your network. Together, those three circles are your community.
The framework appears in full in Chapter 17 of Hacking Communities, "From Seed Head to Flying" — the chapter that covers what happens when a community becomes large enough that its members start carrying it outward on their own.
How the Closeness Circle interact with other Hacking Communities Frameworks
What's the difference between a Core Circle and a Cool Kids Club?
A Core Circle is earned through contribution and carries contribution-earned merit; a Cool Kids Club is granted through status and carries only privileges. That is the entire difference, and it decides whether the framework builds belonging or breaks it. The people closest to your core do get insider access and privileged information, but they also take on more responsibility. They are expected to act for the common good, to represent the community, and to make sure their words and actions reflect its core.
The people in your Core and Inner Circle are not the ones who think they're more special than everyone else. It's the opposite: they're the ones committed to everyone else's success, smoothing the path for whoever comes next.
Belonging in the innermost circles is not a prize. It is an honor, which is a different thing. A prize is won and kept. An honor is earned and carries responsibility. It is a place reached by those who choose to contribute more, work harder for the shared purpose, and collaborate more often. The privilege — and this is the irony worth sitting with — belongs to the people who worked hardest to make room for everyone else.
A contribution-led system also tends to produce a more diverse inner circle than a status-led one.
When entry is earned through what someone gives rather than how well they fit in, you end up with a genuine collection of top contributors rather than a self-selecting squad of look-alikes. Diversity ensures representation, which means a wider range of ways of thinking and feeling is covered. It also says something good about you as a leader: that you are welcoming people on the basis of shared values expressed through action, rather than appearance.
This is not a competition. The most collaborative people simply tend to arrive first.
How this connects to the other frameworks
The Member Contribution Journey and Lifecycle — Closeness Circles translated into a linear framework. If the Circles show you the layers, the Journey shows how someone travels between them, and the Lifecycle tells you how long that takes. I developed both from Chapter 17 to make it usable by a team.
Lighthouse, Port, City — the activity-side counterpart. Closeness Circles tells you how close each person is; Lighthouse, Port, City tells you what to build for each depth.
The Dandelion Lifecycle — Closeness Circles belongs to the Seed Head and Flying stages, when a community is large enough that its layers genuinely differ.
Engineering Serendipity — frequency, density, and catalysts are the levers that move people inward.
The Core Values of Community — authenticity, humility, and abundance are the foundational operating mechanism that allows any community to flourish. Learn why.

The Closeness Circles: Trust Leads to Growth
As your community grows, you inevitably create space for new roles within it. A well-designed communication system allows people in the outer layers to get to know you better while growing into a closer level of trust, and rewards people in the innermost circle for their contribution.
The variable in this diagram is vulnerability. The closer to the core, the more vulnerable you are with the people included.
The best way for a member to move deeper into the core of the Closeness Circles is through wholehearted (genuine) contribution. The closer to your inner circles, the more their role in the community becomes essential.
Those who feel the most belonging will likely develop a sense of ownership towards it and raise their hands to help it grow. Ownership leads to higher contribution. Your top contributors are often the ones you must communicate with the most. As relationships deepen, so does communication. By allowing people to create value within your community, you welcome highly committed members to your core circle, making space for them to step into your inner circle.
Closeness brings in more intimate conversations, which implies trust.
Exploring Closeness Circles LAYERS
1: Core
2: Inner circle
3: Network
4: Crowd (beyond the circle, outer layer)
The more inward we dive, the deeper we go within a community. For example: sharing something with your broader network that has not yet been communicated to your team is unreasonable.
The more aware they are of the happenings, the shortcomings, and the latest news, the closer they feel to you. In other words, communication can build trust and engineer closeness levels within your community. Most importantly, belonging to these layers must be a transparent and merit-driven process based on how much people have given back to the community. It is not a competition.
Belonging to the innermost circles should not represent a reward, although it should be an honor to belong there. The most collaborative are likely get in first.
The core and inner circles should be represented by the people who have given the most to your community, worked the hardest to give back to others and helped create a safe space for everyone.
