Types of Communities and How to Choose — Five Patterns Organized by Purpose
What is a community? — Align the definition first
When someone says “I want to build a community,” the image in each person’s head is wildly different. Some imagine a salon-type paid membership organization; others picture a Slack workspace or the regular gathering of a study group.
Here, we define a community as follows:
A place where people who share a common purpose, interest, or attribute continuously build relationships.
Temporary events and one-way information dissemination are excluded. The essence of a community is that “two-way exchanges” continue to emerge between participants, or between operators and participants.
The five types — Quick-reference table
To grasp the whole picture first, here are the five patterns by purpose at a glance.
| Type | Who it connects | Main business KPIs | Operational cost |
|---|---|---|---|
| Customer community | Company ↔ Users | Retention / LTV improvement | Medium–High |
| Internal community | Employees ↔ Employees | Recruiting / engagement | Low–Medium |
| Fan community | Brand ↔ Fans | Awareness / purchase conversion | Medium |
| Learning community | Learners ↔ Learners | Skill acquisition / network | Medium |
| Local / theme community | People along a local or theme axis | Solving social issues / regional revitalization | Low–Medium |
The five community types by purpose
1. Customer community
A community that gathers users of your service or product to drive adoption and improve loyalty.
| Item | Content |
|---|---|
| Suited organizations | SaaS / subscription-type, companies prioritizing long-term customer relationships |
| Source of value | Sharing challenges and exchanging know-how among users |
| Linked initiatives | Customer success, lateral expansion of usage cases |
| Operational cost | Medium–High (often requires a dedicated person) |
2. Internal community
A community that creates cross-team connections within the organization, driving engagement and knowledge sharing.
| Item | Content |
|---|---|
| Suited organizations | Remote-work-centric, large organizations with strong silos |
| Source of value | Cross-departmental, accidental dialogue and knowledge sharing |
| Operational tip | Producing the feeling of “non-work safety,” executive participation |
| Operational cost | Low–Medium (easy to start by leveraging existing tools) |
3. Fan community
A community where fans of a brand, creator, or individual gather to enjoy support, exchange, and co-creation.
| Item | Content |
|---|---|
| Suited organizations | D2C, content businesses, sports clubs — brands with high-energy fans |
| Source of value | Lateral connections among fans / empathy |
| Operational tip | Producing a feeling of “specialness,” operators stay in the background |
| Operational cost | Medium (content emerges easily but flame-up risk management is also needed) |
4. Learning community
A community designed as a place to learn specific skills or knowledge together.
| Item | Content |
|---|---|
| Suited organizations | Education, training, certification businesses; companies seeking to network specialist talent |
| Source of value | Sharing progress, output opportunities, mutual feedback |
| Operational tip | Avoid fixing “teach/learn” roles; provide regular presentation slots |
| Operational cost | Medium (curriculum design and facilitation require resources) |
5. Local / theme community
A community that gathers around local ties or a specific theme (environment, parenting, hobbies, etc.).
| Item | Content |
|---|---|
| Suited organizations | Locally rooted businesses, NPOs, government; companies seeking to link CSR activities to the business |
| Source of value | Empathy, pure engagement with the purpose |
| Operational tip | Partnerships with other groups; provide multiple slots where participants can become leaders |
| Operational cost | Low–Medium (sometimes runnable on a volunteer basis) |
How to choose the type — Three axes
If you still hesitate after laying out the five types, narrow down using these three axes.
| Axis | Question | Direction |
|---|---|---|
| Connection | Who do you want to connect with whom? | Customers / employees / fans / learners / local |
| KPI connection | Which business indicator should it contribute to? | Retention / recruiting / awareness / skill / social issue |
| Resources | How many hours can you put into ongoing operation? | Few → internal / local / Many → customer / learning |
Using the diagnostic tool below, you can find the recommended type just by answering three questions.
Summary — The first thing to do after choosing a type
Once the community type is decided, what’s next is to document the three points of “purpose, audience, and place.”
| Element | Question |
|---|---|
| Purpose | What does this community exist for? |
| Audience | Who do you want to participate? (eligibility, ideal member profile) |
| Place | On which platform will you run it? |
Just by creating a one-page “community design sheet” that captures these three points, the launch direction aligns and it becomes the starting point for everything from inviting the first members to operational decisions.
A community is harder to keep going than to start. Choosing the type correctly is the first step toward a community that lasts.

Frequently asked questions
- Q. Why does the "type" of a community need to be decided first?
- A. Because the type significantly changes the operational priority indicators, the people required, the suitable platform, and the launch order. Starting to run without deciding the type misaligns the participant profile and operational actions, and is the cause of policy swing across initiatives.
- Q. Is it OK to change the type once it has been decided?
- A. It is possible, but because participants' "expectations" change, designing communication for the transition period is essential. In general, we recommend reconsidering redesign on a quarterly cycle, triggered by annual business strategy reviews or shifts in the participant base.
- Q. How are customer communities and fan communities different?
- A. A customer community has the main purpose of "user support and loyalty improvement for our own product," and exchange of usage know-how is central. A fan community is "a place where fans of a brand or person gather," and empathy and support are central. Even at the same company, when the purposes differ, both are sometimes run separately.
- Q. For B2B SaaS, which type is suitable?
- A. In many cases the "customer community" is central, but if the target segment is decision-makers, a setup combining a "learning community" or "theme community" can be effective. The optimal type changes depending on whether the goal is LTV maximization or industry-wide enlightenment.
- Q. Are there community types beyond these five?
- A. If you subdivide further there are many — "OSS communities," "creator communities," "investor communities," and so on — but from an operational viewpoint, most can be organized as one of the five types introduced here, or as a combination. We recommend first thinking through the lens of the five types.
