Latest / Community Marketing with Fexingo: Discord, Slack Groups, and Brand Communities / How a $30 Million Community Runs on Volunteer Moderators
Transcript
- Lucas: There's a Slack community for product managers — it's called Product School Community, though everyone just calls it the PM Slack — and it does something that sounds almost impossible. It has about 200,000 members, generates north of $30 million a year in revenue, and the bulk of its day-to-day operations are run by volunteers. Luna: Wait — volunteer moderators manage a community that's generating $30 million? That's not a small side project. That's real revenue. Lucas: Exactly. And it's not like they're skimping on quality. The community is famously high-signal. You ask a tricky product question at 10 PM on a Tuesday and you'll get a thoughtful reply from a senior PM at Spotify or Stripe within minutes. That doesn't happen by accident. Luna: So how do they get people to give that level of attention for free? I've seen communities where even paid mods burn out after six months. Lucas: The key insight is they don't treat volunteers as free labor. They treat them as an exclusive membership tier. The community has a free tier — anyone can join — and a paid tier called Product School Pro, which costs about $200 a year. But the volunteer moderators get Pro access for free, plus a few specific perks. And the perks aren't cash or equity. Luna: What are they? Lucas: Three things. One: a private Slack channel just for moderators, where they share job leads and advice. Two: a monthly 'office hours' with a well-known product leader — think Marty Cagan or Teresa Torres — where moderators get to ask questions directly. And three: a small badge on their community profile that says 'Moderator.' That's it. No salary, no bonus, no stock. Luna: So the incentive is mostly status and access. That only works if the community is already prestigious enough that people want that badge. Lucas: Exactly right. The community reached critical mass first — about 80,000 members — before they formalized the volunteer program. By that point, being a moderator was already seen as a mark of expertise. The badge became a kind of credential you could put on LinkedIn. Some members even wrote on their resumes that they were a community moderator, and hiring managers knew what that meant. Luna: I've seen that happen in developer communities too. But the risk is that volunteers drift off after a few months. How do they keep a 40-person team active? Lucas: They have a very structured rotation. Each volunteer commits to a minimum of four hours per week for six months. After six months, they can re-up or step back. About 60 percent renew. The community has a pipeline of new applicants — they get about 100 applications for every 10 moderator slots. So churn is actually healthy because it brings in fresh perspectives. Luna: But four hours a week of high-quality moderation — answering questions, enforcing guidelines, welcoming new members — that's real work. How do they train people to do it well? Lucas: New moderators go through a two-week onboarding that's almost like a boot camp. They shadow an existing mod, they read a detailed playbook that covers edge cases — how to handle a spammer, how to respond to a heated argument, when to escalate to the small paid community team. And they have to pass a sort of 'moderation quiz' before they get full permissions. Luna: A quiz? That's actually kind of brilliant. It signals that the role is serious. Lucas: Exactly. And it filters out people who just want the badge but aren't willing to learn. The community manager — who is one of the only five paid staff members focused on the community — told me that the quiz has a 70 percent pass rate. So it's not a gatekeeper, but it does ensure baseline competence. Luna: So the paid team is only five people for a 200,000-member community? That's a ratio of 1 to 40,000. Most SaaS companies aim for one community manager per 5,000 members. Lucas: Right. And that's the economic secret. The community's operating costs are incredibly low. The biggest expense is Slack's enterprise plan — which for a community that size is about $100,000 a year. Then salaries for the five-person team. Everything else is variable and small. Meanwhile, the paid tier has tens of thousands of subscribers at $200 a year. The gross margin on that revenue has to be over 90 percent. Luna: That's a phenomenal business. But it only works if the value of the free tier is high enough that people want to upgrade for more. What does the paid tier actually offer that free doesn't? Lucas: Paid members get access to a library of recorded courses, templates for product roadmaps and PRDs, and a few exclusive channels — including one where they can get direct feedback from the moderators. But honestly, the main driver of upgrades is the perception that paid members are more serious. There's a subtle social signal. And the community reinforces that by having the free tier be genuinely useful, so people feel good about supporting it. Luna: So the volunteers are essentially creating the value that drives the paid conversion. And they're doing it for recognition, not money. Lucas: That's the loop. The volunteers make the free tier excellent, which attracts more members, some of whom convert to paid, which funds the infrastructure and the small paid team, which supports the volunteers. It's a self-reinforcing cycle. And the key is that the volunteers don't feel exploited because they're getting something they value more than cash — career capital and community standing. Luna: I can think of a dozen brands that would love to replicate this. But most communities don't have that kind of built-in prestige. What's the takeaway for someone starting from scratch? Lucas: You don't need to start with volunteers. The Product School community spent years building a strong free culture before they formalized anything. But you can design for volunteer readiness from day one. That means: clear community guidelines, a culture of peer recognition, and a way for members to earn visible status. Even a simple 'member of the month' feature can lay the groundwork. Luna: And don't underestimate the power of a private channel for your top contributors. That's zero cost and creates a sense of insider access. Lucas: Exactly. The private moderator channel in PM Slack is where the real networking happens. People share job openings that never hit the public channels. One moderator told me they got their current role through a connection they made in that channel. That kind of organic benefit is more powerful than any formal reward you could design. Luna: It's like a guild. You earn your way into a trusted inner circle, and the circle itself becomes the reward. Lucas: And that's why the model is so hard to copy directly. You can't just slap a badge on people and expect them to moderate for free. You need to genuinely make the inner circle valuable. That takes time and intentional culture building. But once it's in place, you have a marketing engine that doesn't cost you a dollar in salary. Luna: If today was actually useful to you — and I know Lucas and I get a lot of messages from people who've used these community ideas in their own work — the way these episodes stay ad-free is listener support. It's buy me a coffee dot com slash fexingo. No pressure, just a way to keep the conversation going. Lucas: She's right. We don't run ads, we don't have sponsors, and we want to keep it that way. If you've gotten something out of any of these episodes, that link is how you make sure we can keep doing this. Appreciate every single person who's chipped in. Luna: Yeah. And back to that moderator model — one thing I've been wondering is whether the community will eventually need to pay moderators as it grows. At some point, does the volunteer model hit a ceiling? Lucas: That's the million-dollar question. The community is currently at about 200,000 members. The founder has said publicly that they might need to hire a few more paid community managers if they double again. But the volunteer core has scaled surprisingly well because each moderator handles only a small slice — maybe 5,000 members each. And the culture is strong enough that people are willing to step up. Luna: So the ceiling might be higher than you'd think, as long as the prestige holds. Lucas: Exactly. And that prestige is tied to the quality of the community. If the community ever declines, the volunteers will leave, and the model breaks. But for now, it's a beautiful flywheel. And one that a lot of brand communities could learn from — even if they never reach 200,000 members.
