Community-led growth: Discord, Slack, Circle — measured right

Short answer

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 Takeaways

  • Track the share of members active each week and watch the trend.
  • Look for members replying to each other, not only to the founder.
  • Track how much revenue comes from community members over time.

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?

There's no fixed number, but a community needs enough regularly active members that new joiners see conversations happening.
