TL;DR
Communities compound slowly and fail loudly. The three metrics that predict success — weekly active ratio, member-to-member replies, and community-sourced revenue — separate genuine growth channels from vanity Discords.
Key facts
- Healthy weekly active ratio: 20%+ of total members active weekly.
- Member-to-member reply ratio: 3+ replies from other members for every founder post.
- Community-sourced revenue: 10%+ of ARR attributable to community members within 12 months.
The three metrics that matter
- Weekly active ratio — measures real engagement, not signup vanity.
- Member-to-member reply ratio — measures whether the community can run without you.
- Community-sourced revenue — the only metric your board cares about.
Frequently asked questions
Discord, Slack, or Circle?
Discord for consumer and developer audiences, Slack for B2B professionals, Circle for premium paid communities. Pick where your buyers already spend time — don't ask them to install a new app.
How big before it's viable?
150 active weekly members. Below that, silence dominates and new joiners leave.
