Latest / Community Marketing with Fexingo: Discord, Slack Groups, and Brand Communities / How a 50-Person Slack Group Replaced a Million-Dollar Agency
Transcript
- Lucas: There's this assumption in B2B marketing that you need scale — thousands of members, millions of impressions, a big agency behind you. And then you hear about a startup that built a 50-person Slack group and replaced their entire million-dollar agency. Luna: Fifty people? That's smaller than most marketing departments. Lucas: Exactly. The company is ShieldLayer — they're a mid-market cybersecurity firm, not a household name. In 2024, their CMO decided they were spending way too much on an external agency for demand gen. The agency was generating leads, sure, but the cost per qualified lead was north of $4,000. So she shut down the agency contract and put that budget into building a community. Luna: Bold move. What kind of community? Lucas: A private Slack group for chief information security officers — CISOs. Invitation-only, capped at 50 members initially. The rule: no product pitches, no vendor content, no ShieldLayer salespeople in the room. Just CISOs talking to each other about threats, breaches, tooling decisions. Luna: So it's basically a peer advisory group. But how does that generate revenue? If there's no product talk, how do people even know ShieldLayer exists? Lucas: That's the counterintuitive part. ShieldLayer's CMO, her name is Danielle Reyes — she told me the goal was never to talk about their product. The goal was to be the host of the conversation. The brand becomes the facilitator, not the seller. And because the conversation is high-signal — real threat intel, real vendor evaluations — the group built immense trust. Luna: Trust being the currency that eventually converts. Lucas: Exactly. Within 18 months, that 50-person Slack group had generated over $8 million in closed-won revenue. The average deal size was about $160,000. And here's the kicker: most of those deals never involved a demo request or a typical sales outreach. They started when a CISO in the group asked, 'Hey, who are you using for endpoint detection?' and another member said, 'We switched to ShieldLayer six months ago. Here's what we learned.' Luna: So it's peer to peer selling, but the company doesn't even have to ask for it. Lucas: Right. They created the conditions for the referral to happen naturally. And because the group is small and invitation-only, the signal to noise ratio is incredibly high. No spam, no vendor pitches, no 'check out our new whitepaper.' Just CISOs helping CISOs. Luna: I love that. But I'm wondering — how do you recruit the first 50 people? If you're not a well-known brand, getting CISOs to join a random Slack group has to be tough. Lucas: Danielle started with her own network — former colleagues, people she'd met at conferences. She personally invited 15 CISOs she trusted. Then she asked each of them to invite one or two peers. The key was the framing: 'This is not a vendor group. This is a private space where you can talk candidly about security challenges. I'm just hosting it.' No one said no. Luna: So the exclusivity itself became a draw. Lucas: Absolutely. Once you have 15 credible people, the next 35 are easy because nobody wants to be the one not in the room. And Danielle enforced the no-product rule strictly. The first time someone from another vendor tried to slide into the DMs with a pitch, they were removed from the group. No warnings. Luna: That's hard. Most companies would cave and try to monetize the group too early. Lucas: Most companies do. But Danielle had a mantra: 'The community is not a sales channel. It's a trust factory.' And she had the data to back it up. She tracked every referral that came through the group — not by asking members, but by tagging the source in their CRM. Every time a deal had a community member's name mentioned, they logged it. After 18 months, the community-attributed revenue was $8.2 million. Luna: That's a clear ROI. But let's talk about an edge case — what if a competitor joins the group? Doesn't that create tension? Lucas: It happened. A CISO from a competitor — let's call them Sentinel — joined the group. And at first, Danielle was nervous. But within a month, that competitor's CISO became one of the most active, helpful members. She was answering questions, sharing threat intel, being genuinely useful. And then something interesting happened: that CISO's company ended up partnering with ShieldLayer on a joint integration. The community actually turned a competitor into a partner. Luna: That's wild. So the community became a trust bridge even between rivals. Lucas: Exactly. Because the norm was so strong — no selling, just helping — everyone felt safe participating. And when you participate honestly, you build respect. That respect often translates into business, but indirectly. Luna: So what's the biggest lesson for a B2B marketer listening right now who wants to start something similar? Lucas: Start smaller than you think. Don't try to build a 1,000-person community. Start with 20. Make it exclusive. Make it genuinely valuable — that means you, as the host, have to facilitate conversations, share insights, maybe even bring in external experts. And for heaven's sake, do not pitch your product. Let your customers do that for you. Luna: And measure the right things. Not message count or member growth, but referral revenue. Lucas: Right. Danielle tracked exactly one primary metric: community-influenced revenue. She didn't care about how many messages were sent per day. She cared about how many deals had a community member's name attached. That's the north star. Luna: It's a beautiful case study. And it makes you think — we do a lot of shows like this on Fexingo, and we never run ads. The whole network is ad-free. And if these marketing conversations have sparked something you've actually used, there's a way to support that choice. Lucas: Yeah, it's buy me a coffee dot com slash fexingo. No pressure, but if the show's been useful, that link is how you keep it free and independent. Luna: Exactly. And now back to the community — one thing I find fascinating is how ShieldLayer eventually scaled the group. Did they keep it at 50? Lucas: They did. They intentionally kept it at 50. When someone left or became inactive, they'd invite a new person. They never wanted it to become a broadcast channel. The intimacy was the whole point. And they created a secondary, larger community — about 300 people — for threat briefings that were more one-to-many. But the core 50-person group remained the engine. Luna: So the small group is for peer connection, the larger group is for content distribution. Lucas: Exactly. And the larger group feeds the small group. When someone in the 300-person group consistently adds value in the threat briefings, they get an invite to the 50-person group. It's like a membership ladder. Luna: That's smart. It also creates aspiration — people want to earn their way into the inner circle. Lucas: Danielle called it 'the velvet rope strategy.' Make the inner circle visible but not accessible. People see the value, they contribute in the outer group, and then they get invited in. It's the opposite of most communities, where you let everyone in and then try to filter later. Luna: So the barrier to entry is actually value contribution, not just a title. Lucas: Right. And because the barrier is meaningful, the people who make it in are deeply engaged. They're not lurkers. They're the CISOs who are already answering questions in the larger group, sharing threat intel, being generous with their time. So when they enter the 50-person group, they immediately add to the signal. Luna: I want to ask about the threat briefings. What made those so valuable? Lucas: Every Tuesday morning, ShieldLayer would compile a briefing — not about their product, but about the three most significant security threats they'd seen in the past week. They'd share it in the community. It was written in plain language, actionable, and often included indicators of compromise that members could use immediately. That briefing became the most forwarded piece of content they ever produced. Luna: So the community was getting exclusive, timely intelligence that they couldn't get from a blog or a newsfeed. Lucas: Exactly. And the fact that it came from ShieldLayer — the host — built tremendous authority. But Danielle was careful never to say 'this is because of our product.' The briefings were based on aggregated data from their threat research team, but they shared it freely. No gating, no demo request. Just value. Luna: That's a great example of content marketing that's genuinely useful, not just lead-gen bait. Lucas: And it worked because it was integrated into the community, not separate from it. The briefing was posted in the Slack channel, and then the conversation about it happened in the thread. So the content sparked the discussion, and the discussion deepened the relationship. Luna: One more question: what happened when ShieldLayer tried to grow beyond cybersecurity? Did they consider expanding into adjacent verticals? Lucas: They did, briefly. They started a second Slack group for IT directors at mid-size companies. Same format, same rules. It never took off the same way. Danielle's conclusion was that cybersecurity CISOs are a uniquely tight-knit group — they share a common adversary, a common regulatory burden, and a common language. The community worked because the audience was naturally cohesive. Luna: So the lesson is: pick a niche where the shared pain is real and specific. Lucas: Exactly. Don't force community where the common ground is thin. The best communities form around a genuine, urgent problem that people can't solve alone. That's what made the ShieldLayer group thrive — every member had a target on their back, and they needed trusted peers to survive. Luna: And the brand that hosts the conversation becomes the trusted partner by default. Lucas: Without ever having to say 'buy our product.' That's the magic. And it's replicable in any B2B niche where the customer's pain is deep and the stakes are high. Luna: Great episode. I think the key takeaway is: start tiny, be generous, and let your customers do the talking. Lucas: Couldn't agree more. That's it for this one. See you next time.
