Community Discovery
When to Use
- Founder wants to find online communities where their target customers are active
- Founder wants to identify channels for organic promotion and community-led growth
- Founder wants to build relationships in relevant communities before launching
- Founder wants to find beta testers, early adopters, or design partners
- Founder wants distribution beyond paid ads and cold outreach
Context Required
- Target customer profile (role, industry, interests, seniority)
- Product category and the problem it solves
- What the founder wants from communities (feedback, users, partnerships, awareness)
- Founder's bandwidth for community engagement (lurk and post vs. become a regular)
Workflow
- Map the community landscape — identify where your target audience spends time online:
- Reddit: find subreddits by searching for the problem you solve, competitor names, and industry terms. Check subscriber count, post frequency, and moderation rules.
- Slack: search Slofile, Slack directories, and Google "[industry] slack community" to find relevant workspaces.
- Discord: search Disboard, Discord.me, and Google "[topic] discord server" for relevant servers.
- Forums & others: Indie Hackers, Hacker News, Stack Overflow, niche forums, Facebook Groups, LinkedIn Groups.
- Qualify each community — not all communities are equal. Score each on:
- Relevance: does your target customer actually hang out here?
- Activity: are there regular posts and discussions (not a ghost town)?
- Size: big enough to matter, small enough to stand out (sweet spot: 1K-50K members)
- Promotion tolerance: does the community allow product mentions, or is it strictly no self-promotion?
- Quality of discussion: are conversations substantive or just spam and memes?
- Categorize by engagement type — sort communities into:
- Promote: explicitly allows product sharing, launch announcements, or "Show X" posts
- Contribute-first: allows organic mentions if you're a genuine, helpful member first
- Listen-only: valuable for research and voice-of-customer, but no promotion allowed
- Build the engagement plan — for each community:
- Join and observe for 1-2 weeks before posting
- Identify the norms (how do regulars communicate? what gets upvoted/praised?)
- Plan your first 5 contributions (helpful answers, not product pitches)
- Plan when and how to introduce your product (if appropriate)
- Create the community map — output a prioritized list with engagement strategy for each.
Output Format
## Community Map for [Product/Category]
### Tier 1 — High Priority (engage weekly)
**[Community Name]** — [Platform]
- Link: [URL]
- Members: [count] | Activity: [posts/day or week]
- Relevance: [why your target customer is here]
- Rules: [promotion policy summary]
- Engagement type: [Promote / Contribute-first / Listen-only]
- Strategy: [specific plan — what to post, how to contribute, when to mention product]
- Key threads/channels: [specific channels or recurring threads to participate in]
### Tier 2 — Medium Priority (engage biweekly)
...
### Tier 3 — Monitor (check monthly)
...
### Engagement Calendar
| Week | Community | Action | Goal |
|------|-----------|--------|------|
| 1 | [name] | Join, read top 20 posts, identify norms | Understand culture |
| 2 | [name] | Answer 3 questions, no product mention | Build reputation |
| 3 | [name] | Share insight related to your space | Establish expertise |
| 4 | [name] | Soft product mention in relevant thread | Drive first traffic |
Frameworks & Best Practices
The 10:1 rule: Give 10 valuable contributions for every 1 product mention. Communities have long memories — one spammy post can get you banned and your brand damaged permanently.
Platform-specific tactics:
| Platform | Best for | Promotion approach |
|---|
| Reddit | Problem validation, feedback, launch day | Answer questions in comments, share in relevant "share your project" threads. Never post direct ads. |
| Slack | B2B relationships, warm intros | Be helpful in channels for weeks before mentioning your product. DMs only after building rapport. |
| Discord | Developer communities, gaming, crypto | Participate in discussions, share expertise, use #showcase or #self-promo channels if they exist. |
| Indie Hackers | Founder-to-founder, building in public | Share your journey with real numbers. The community rewards transparency over polish. |
| Hacker News | Developer/technical audience, launches | Show HN for launches. Don't astroturf. Substantive comments build reputation over months. |
| Facebook Groups | SMBs, local businesses, niche B2C | Join groups your customers are in. Respond to "looking for recommendations" posts. |
| LinkedIn Groups | Enterprise B2B, professional services | Low-signal, high-noise — generally not worth the effort unless very niche. |
Red flags — avoid these communities:
- More self-promo than real discussion
- Moderators are inactive or absent
- "Pay to post" or "pay for featured" requirements
- Last meaningful discussion was months ago
- Members are mostly other founders/marketers (not your actual customers)
Common mistakes:
- Joining 20 communities and being active in none (pick 3-5 and go deep)
- Leading with your product instead of being helpful first
- Copy-pasting the same message across communities
- Ignoring community rules and getting banned
- Giving up after 2 weeks because no one clicked your link

Examples
Prompt: "I'm building a tool for data engineers. Where should I be hanging out online?"
Good output includes: A prioritized map of communities — specific subreddits (r/dataengineering, r/apachekafka), Slack groups (dbt Slack, Data Engineering Weekly), Discord servers, relevant HN threads, and a 4-week engagement plan for the top 3.
Prompt: "We're launching our design tool next month. Which communities should I warm up in advance?"
Good output includes: Communities sorted by launch relevance (Designer Hangout Slack, r/UI_Design, Dribbble, specific Discord servers), a pre-launch engagement timeline, and specific "Show X" or "Share your project" threads to target on launch day.
