Growth Without Ads: Why B2B Fintechs Are Betting on Community
When paid ads stop working as well, where do you go? Somewhere more human.
In fintech, growth used to mean cranking up the ad spend and hoping the clicks convert.
But in 2025, the returns are thinner, the competition is fiercer, and trust is harder to buy.
So instead of throwing more money at paid reach, a growing number of fintechs — especially in B2B — are leaning into community: building trusted spaces where users engage, support one another, and shape the product experience together.
What is community-led growth, exactly?
It's a strategy that turns your most engaged users into your best growth engine — through peer support, feedback loops, and authentic advocacy. Think Slack groups, Discord chats, or private forums that aren’t just for answering questions, but for building loyalty.
Not the fluffy kind that lives on a forgotten Discord channel. We’re talking purpose-built, high-signal spaces where users support each other, shape the product, and drive organic growth.
Because when you're trying to reduce your customer acquisition costs (CAC) and keep users around longer, a well-run Slack group — or even a well-run Discord or Telegram channel — might just outperform your entire ad budget.
Why Is Everyone Talking About Community (Still)?
Because let’s face it: ads are expensive, trust is rare, and word of mouth is having a renaissance.
Community works because it’s rooted in trust — and fintech is a trust business.
When users help each other solve real problems, you earn credibility without spending a krona. You also get faster feedback loops, more honest product insight, and a built-in referral engine.
One company significantly reduced pressure on its support desk by empowering a peer-run community — similar to what Kong Inc. , a developer-focused platform, publicly shared about how their user base contributes to support and engagement. Another launched inside a private user group that became its best source of feedback, referrals, and advocacy — echoing tactics seen in tools like 1Password and others using community as part of their onboarding and support loop. These aren’t outliers — they’re signals.
As Foundation Inc puts it: “People trust communities more than companies. That’s why community-led marketing converts.”
Community-led growth isn’t flashy, but it compounds.
Not Just a Slack Channel
Picking the right platform matters. Slack works well for professional audiences — think ops, growth, and partnerships. Discord fits better if your fintech is more dev-centric or builder-focused. Telegram works in more informal or emerging-market contexts.
The key is to go where your users already hang out, not force them somewhere new.
As Foundation Inc notes, “Slack usage has surged 2.5x since 2016, and it's become a place where decision-makers go to learn, not be sold to.”
And once you’re there, don’t just lurk. Show up. Host live sessions, answer questions, ask for feedback. Make the space worth being in.
From Conversations to Conversions
The strongest fintech communities handle support and growth in the same space — just like one developer platform whose user forum became one of their most effective channels for feedback, support, and product adoption.
When you give early users a seat at the table, they help shape the product. For example, one startup used a private Discord group to co-create features with its first 100 users. Another ran monthly feedback calls inside their community, directly shaping their roadmap based on what users asked for. When you run AMAs or share behind-the-scenes updates, they stick around. When you reward contributions with beta access or early features, they become advocates.
And when you do all of that consistently? You’ve got yourself a channel that doesn’t rely on CPMs or algorithms.
The Community Growth Loop
Some of the most effective B2B growth engines look surprisingly low-tech.
Tutorials, shared automations, peer-led onboarding — these community-born assets generate outsized impact. They aren’t just resources — they’re proof of value, created by people who already believe in what you’re building.
It’s peer-led content with built-in credibility. And unlike MQLs pulled in through a cold ad funnel, these users already trust you. They’re more likely to convert — and more likely to stick.
Make It Work
If you’re thinking of going community-first (or community-also), here’s what actually works:
Start small. Aim for 50 truly engaged users instead of chasing 5,000 ghosts.
Define your purpose. Is the community for support, feedback, referrals, or all three?
Be consistent. Show up regularly with polls, office hours, live chats, or even a well-timed meme.
Make participation rewarding. Offer early feature access, recognition, or private updates — not just swag.
Streamline access. Add community invites to your onboarding flows, referral programs, or even your signup confirmation email.
