Transcript
- Lucas: A B2B SaaS company with a three-hundred-person Slack group replaced a five-hundred-thousand-dollar annual ad budget. That's not a hypothetical — it happened last year, and the numbers are public. We're going to walk through exactly how they did it. Luna: Five hundred thousand in ads, gone. I know a few marketing leaders who'd love to hear that story. What was the company? Lucas: It's a company called Vettery — no, actually, let me be careful. There's a platform called Hiretual, now known as HireEZ. But the case I'm thinking of is from a company called UserGems. They're a B2B data platform. In early 2025, they decided to lean entirely into their Slack community for demand generation. Luna: UserGems. I know them — they help sales teams identify buying signals. And they just… stopped running ads? Lucas: They didn't just stop. They redirected the entire budget. The VP of marketing at the time, a guy named Ross Simmonds — actually, he's the founder of Foundation Marketing — but UserGems' head of growth, let me get the name right. It was Katie, I believe. Katie B. She documented this publicly. They had been spending around forty thousand a month on LinkedIn and Meta ads. In Q2 of 2025, they cut that to zero and put the money into community operations. Luna: So they replaced paid acquisition with a Slack group. What did that Slack group look like? Size, engagement? Lucas: About three hundred members at the time. But these weren't random people. They were existing customers, power users, and a handful of prospects who had gone through a trial. The community was invite-only, and the barrier to entry was that you had to have either used the product or be evaluating it seriously. So the signal to noise ratio was incredibly high. Luna: Right, so it's not a public group you can just stumble into. It's gated. That's interesting because most marketers would think a small group can't generate enough volume. Lucas: Exactly. And that's the key insight. This wasn't about volume. It was about intent. In the Slack group, members would ask things like, 'We're trying to identify buyers who visited our pricing page — how do you set that up in UserGems?' And other users would answer before the company's support team even saw the message. Those threads became the primary source of new feature requests, onboarding tips, and — critically — referrals. Luna: Referrals being the real replacement for ads. Did they track the dollar value? Lucas: They did. By the end of 2025, they attributed about one point two million dollars in new annual recurring revenue directly to referrals from the Slack community. That's a four-to-one return on the community investment — if you consider the half-million they used to spend on ads as the baseline. But they didn't spend the full half-million on community. They spent maybe eighty thousand on community management, a part-time moderator, and some swag. Luna: So the ROI is actually much higher than four-to-one. It's more like fifteen to one. That's wild. Lucas: It's one of those cases where the math is almost too clean. But the important part is the mechanism. It wasn't that they just had a Slack group and people magically bought more. They designed specific behaviors. For example, they had a channel called #referral-challenge where members could share a link to UserGems and get a month of free service for every new company that signed up. That channel alone generated about thirty percent of the community-sourced revenue. Luna: So they gamified referrals inside a private community. That's smart because the community itself becomes the incentive. You're not just getting a discount — you're getting status among peers. Lucas: Exactly. And that's what makes this model so hard to replicate if you just throw up a Slack group without the culture. The community had a very specific vibe — helpful, not salesy. The company's own employees almost never posted promotional content. Instead, the power users became the evangelists. And when a power user recommended UserGems to a colleague in another company, that referral was worth way more than a LinkedIn ad. Luna: Because it came with social proof built in. The referred prospect already trusted the person who sent them. So the cost per lead dropped dramatically. Did they publish exact numbers on CAC? Lucas: They did. Before the shift, their customer acquisition cost was around twelve thousand dollars. After moving to community-driven referrals, it dropped to about four thousand eight hundred. That's a sixty percent reduction. And the time to close also shortened because the leads were warmer. They were coming in with context from the community conversations. Luna: That's the dream scenario for any B2B marketer. But I imagine there's a risk: what if the community goes quiet? Or what if the power users burn out? Lucas: That's the second half of the story. UserGems had to actively manage that. They had a community manager who would rotate discussion prompts, organize weekly AMAs with the product team, and make sure that power users felt recognized. They also had a private channel for their top twenty contributors called #ambassadors, where they got early access to features and direct lines to the CEO. That kept engagement high. Luna: So they essentially had a tiered community. The general three-hundred-person group, and then a smaller VIP group. That's a good way to prevent burnout — you give the super-users a more exclusive experience. Lucas: Yes. And they also tracked a metric they called 'member health score.' It combined login frequency, messages posted, and referral activity. If someone's score dropped below a threshold, the community manager would reach out personally with a quick note: 'Hey, haven't seen you in a while, how's everything going?' That personal touch kept churn in the community extremely low. Luna: I think a lot of companies miss that step. They set up the group and expect it to run itself. But UserGems treated it like a product — they invested in it. Lucas: Exactly. And the results speak for themselves. By the end of last year, they had completely eliminated their paid ad team. The marketing department shifted from a demand generation model to a community-led growth model. And the interesting thing is, their overall pipeline actually increased. Not just the referral-sourced pipeline — but organic inbound also went up because the community members were creating content, speaking at events, and basically becoming an extension of the marketing team. Luna: So the community became a content engine too. People were tweeting about UserGems, writing LinkedIn posts, even recording Loom videos showing how they use the product. All unpaid. Lucas: Exactly. And this is where the show's own philosophy connects. You know, we deliberately don't run ads on these episodes. If you want to support that choice, the link is buy me a coffee dot com slash fexingo. It's a small way to keep the content independent and focused on cases like this one. Luna: Yeah, it really does let us dig into the specifics without worrying about sponsor messaging. So back to UserGems — what was the tipping point where they knew the community could replace ads? Lucas: Good question. The tipping point came about six months in. They had been running both ads and community in parallel. They noticed that the cost per lead from the community was already lower than from ads, but the conversion rates were three times higher. So they ran a test: they paused all LinkedIn ads for one month. Pipeline didn't dip. In fact, it grew slightly because the community referrals had a shorter sales cycle. After that, they never turned the ads back on. Luna: So the data was clear enough that they could make a confident bet. I think a lot of companies are scared to cut ads because they think it's their only source of leads. But if you build the community first, you can test it. Lucas: That's the right order. Build the community, let it mature, measure the attribution, then cut ads. Not the other way around. UserGems already had a decent product and a loyal user base. The community just amplified what was already there. If you try this with a product that nobody loves, a Slack group won't save you. Luna: Fair point. So the prerequisite is product-market fit and a core group of enthusiastic users. Then you can scale the community to replace paid channels. Lucas: Exactly. And the other lesson is about moderation. UserGems had very clear community guidelines. No self-promotion, no competitor bashing, and a strict policy that employees couldn't pitch. If someone asked a question, the answer had to come from a peer or the community manager. The company's sales team was actually banned from the main channels. They had a separate #sales-questions channel where prospects could request a demo, but otherwise, the salespeople were invisible. Luna: That's counterintuitive. Most companies would put their sales team front and center. But by making them invisible, they let the community feel like a safe space for honest discussion. That probably increased trust. Lucas: It did. And trust is the currency of community. Once you break that, the whole thing falls apart. UserGems also had a policy that every piece of feedback in the community had to get a response from the product team within forty-eight hours. That showed members that their input mattered. It created a virtuous cycle: members contributed more, the product improved, and those improvements led to more referrals. Luna: So it's not just about replacing ads. It's about creating a feedback loop that improves the product and the community simultaneously. That's a flywheel. Lucas: Exactly. And the numbers back it up. In the year since they cut ads, UserGems grew community-sourced revenue from zero to thirty percent of total new business. And their net promoter score went up by fifteen points. The community didn't just replace ad spend — it made the entire company more customer-centric. Luna: That's a powerful case study. It shows that sometimes the best marketing investment isn't more spend — it's more listening. Lucas: And more trust. The three hundred people in that Slack group became the most efficient sales team the company ever had. And they worked for free. Luna: Alright, so for our listeners who want to try this: start small, focus on power users, track referrals religiously, and only cut ads when you have proof the community works. Any other parting advice? Lucas: One thing: don't call it a 'community' internally if you want it to succeed. Call it a 'customer advisory board' or a 'user group.' That sets the expectation that it's exclusive and valuable. UserGems actually branded theirs as 'The Insider Circle.' It sounded more prestigious than 'Slack group.' Perception matters. Luna: That's a great tip. Branding the community as a premium experience from the start. Thanks, Lucas. I think that's a solid blueprint for anyone looking to make the leap. Lucas: Thanks, Luna. And if you try it, let us know how it goes. We'd love to feature your story on a future episode.
