Community Building for Business Growth

· Felix Lenhard

When I launched my first online community in 2021, I made every mistake possible. I chose the wrong platform, set the wrong expectations, posted too much, moderated too little, and watched 300 members dwindle to 15 within four months. It was, by any measure, a failure.

But those 15 people who stayed? They became some of my best clients, closest collaborators, and most reliable referral sources. One of them introduced me to the person who eventually became my publisher. Another referred a €60,000 consulting engagement. A third became a business partner on a project that ran for two years.

That failure taught me something counterintuitive: community size is irrelevant. Community depth is everything. And building depth requires a completely different approach than building an audience.

Most founders confuse community with audience. An audience watches you. A community connects with each other. An audience consumes your content. A community creates value together. An audience grows through marketing. A community grows through membership experience.

This distinction changes everything about how you build, manage, and monetize a community. Here’s what I’ve learned from building three communities — one failure, one modest success, and one that now drives meaningful revenue.

Why Community Beats Audience for Revenue

Let me share some numbers that shifted my perspective permanently.

My email list has roughly 3,500 subscribers. My LinkedIn following is around 4,000. My community has 220 active members. Guess which channel generates the most revenue per person?

The community isn’t even close — it generates approximately 8x more revenue per member than my email list and 25x more than my LinkedIn following. The reasons are structural:

Trust compounds within a community. When someone sees me interact with members over weeks and months, answering questions honestly and sharing what’s actually working, they build trust that no amount of content marketing can replicate. By the time they’re ready to buy something, the trust barrier is already cleared.

Members sell for you. When a new member asks “Has anyone worked with Felix on [topic]?” and three other members share positive experiences, that’s more powerful than any testimonial I could collect. Peer validation within a community is the strongest form of social proof available.

You learn what to sell. Community conversations are the best market research you’ll ever do. Every question, complaint, and request tells you exactly what your audience needs. I’ve built three profitable offerings based directly on questions that came up repeatedly in community discussions.

This connects to the referral flywheel concept. A community is essentially a concentrated referral network where members advocate for you in real-time, to exactly the people who are most likely to buy.

Choosing the Right Platform (It Matters Less Than You Think)

I’ve seen founders spend months evaluating community platforms. Slack vs. Discord vs. Circle vs. Mighty Networks vs. Facebook Groups vs. custom solutions. Here’s the truth: the platform matters about 10% as much as the community design and management.

That said, here’s what I’ve learned about each:

Slack: Best for professional, small-to-medium communities (under 500 members). People already use it for work, so the friction to participate is low. Downside: conversations are ephemeral, and it’s hard to build a content library.

Discord: Best for larger, more active communities. Better organization than Slack with channels and roles. Downside: it has a gaming reputation that can feel mismatched for business communities, especially in the DACH market.

Circle: Purpose-built for communities. Good structure, decent discovery features, integrates with course platforms. Downside: it’s another login and another app, which creates adoption friction.

Facebook Groups: Largest potential reach, lowest adoption friction (everyone’s already on Facebook). Downside: you’re building on someone else’s land, the algorithm controls visibility, and the demographic is shifting older.

My current community runs on Circle, but I’d be equally happy on Slack. The choice should depend on one thing: where your members already spend time. If your audience is technical founders, Slack or Discord. If they’re non-technical small business owners, Facebook or Circle. Don’t make them learn a new tool.

The First 50 Members: Quality Over Speed

The first 50 members define your community’s culture forever. This isn’t an exaggeration. In every community I’ve studied, the norms, tone, and quality of discussion are established by the founding members and rarely change significantly after that.

This means your launch strategy should prioritize quality over quantity:

Start with personal invitations, not public launches. Identify 20-30 people you already know who match your ideal member profile. Send them a personal message: “I’m building a small community for [specific type of person] to [specific purpose]. I’d love for you to be one of the founding members. No cost — I just need committed people who’ll help shape what this becomes.”

Screen members. Yes, even for a free community. A simple application form with three questions — who are you, what do you do, what do you hope to get from this community — filters out passive joiners and ensures you’re starting with engaged people.

Set expectations from day one. My community welcome message includes: what this space is for, what it’s not for, how often I expect members to participate, and the one rule (be useful or ask questions — no self-promotion without context).

Be the most active member for the first 60 days. Post daily. Respond to every comment. Start discussions. Ask questions. Your activity level sets the norm. If you post once a week, your members will post once a month. If you post daily and engage meaningfully, they’ll follow.

Getting those first 50 engaged members typically takes 4-8 weeks. Don’t rush it. The temptation to “open the floodgates” and promote publicly too early is strong. Resist it. A community of 50 engaged members is more valuable than a community of 500 passive ones.

Content and Engagement That Sustains Participation

Most communities die because they become one-directional. The founder posts, members occasionally react, engagement drops, members leave. Here’s how to prevent that:

The 60-30-10 content split:

  • 60% member-generated content (questions, discussions, wins, challenges)
  • 30% facilitated discussions (topics you seed, AMAs, themed threads)
  • 10% your original content (exclusive insights, behind-the-scenes, early access)

The key is that 60% number. Your primary job is not to create content for the community — it’s to create conditions for members to create content. You do this through:

Weekly prompts. Every Monday, I post a question. “What’s the one thing you’re focused on this week?” or “What’s the biggest challenge you’re facing right now?” These prompts give members permission to share and create a regular rhythm.

Win celebrations. A dedicated channel or thread for members to share wins. Nothing builds community culture like celebrating each other’s successes. I respond to every win post personally.

Accountability pods. Groups of 3-5 members who check in with each other weekly on their goals. These create deep connections between members that transcend the community itself. Accountability pods are, in my experience, the single most valuable feature a community can offer.

Monthly expert sessions. Once a month, I bring in a guest — a tax advisor, a marketing specialist, a legal expert — for a live Q&A. These sessions provide massive value and give members a reason to show up regularly.

Direct introductions. When I notice two members could benefit from knowing each other, I introduce them directly. “Hey [Member A], you should connect with [Member B] — you’re working on similar challenges.” This matchmaking is one of the most appreciated things I do, and it strengthens the web of connections that holds the community together.

The principles from my email nurture approach apply here too: provide genuine value consistently, and the relationship deepens over time. Push too hard on selling and you’ll drive people away.

Monetizing Without Destroying the Community

Here’s where it gets tricky. You’re building a community to grow your business, but if the community feels like a sales funnel, it dies. The balance is delicate but achievable.

Model 1: Free community, paid offerings. The community itself is free. Revenue comes from products, services, or courses that serve the community’s needs. This works because the community builds trust, and trust converts to sales when you offer something relevant. My primary community follows this model.

Model 2: Paid community. Charge for membership. This works when the community itself provides enough value to justify a fee — exclusive content, networking, expert access, accountability. Typical pricing for B2B communities: €29-99/month. The advantage is that paying members are more engaged. The disadvantage is a much smaller potential membership.

Model 3: Freemium. Free basic membership, paid premium tier with additional benefits. This is the model I’m moving toward. The free tier serves as the entry point and relationship builder. The paid tier offers exclusive sessions, direct access, and additional resources.

Regardless of model, the rules for monetization are:

  • Never sell in the general community space. If you have an offer, create a dedicated channel or send a direct message.
  • Only sell things the community has asked for. If members keep asking about X, create a solution for X. Don’t push solutions for problems they don’t have.
  • Be transparent about the business model. “This community is part of how I build my business. Here’s how it works.” People respect honesty far more than hidden agendas.
  • Maintain a value ratio of at least 10:1. For every selling moment, deliver ten moments of genuine value.

The same principle from profit-first thinking applies here: be intentional about the financial structure from the start. Don’t build a community and then figure out how to monetize it. Know from day one how the community connects to your revenue model.

Measuring Community Health

Vanity metric: member count. Useful metrics: everything below.

Monthly Active Members (MAM). What percentage of members participated (posted, commented, or reacted) in the past 30 days? Healthy communities: 30-50% MAM. Below 20%: something needs to change.

Thread depth. How many replies does the average discussion thread receive? One-reply threads mean people are posting but not engaging with each other. Aim for average thread depth of 3+.

Member-generated content ratio. What percentage of posts come from members versus you? If you’re generating more than 40% of the content, the community is too dependent on you.

Net Promoter Score. Survey members quarterly: “How likely are you to recommend this community to a colleague?” Scores above 50 indicate a healthy community. Below 30: investigate.

Revenue attribution. Track how much revenue is directly or indirectly attributable to community membership. This justifies the time investment and helps you make smart decisions about community growth.

I review these metrics monthly. It takes about 20 minutes and gives me a clear picture of whether the community is healthy, growing, or needs intervention. This review is part of my broader weekly control system where I check all my key business metrics.

Takeaways

  1. Community depth beats community size. 200 engaged members generate more revenue than 20,000 followers. Focus on depth of connection, not breadth of reach.

  2. Your first 50 members define the culture. Use personal invitations, screen members, set clear expectations, and be the most active participant for the first 60 days.

  3. Use the 60-30-10 content split. 60% member-generated, 30% facilitated, 10% your original content. Your job is to create conditions for member participation, not to be the content machine.

  4. Monetize through trust, not pressure. Free community with paid offerings, paid membership, or freemium. Only sell what the community has asked for, and maintain a 10:1 value-to-selling ratio.

  5. Measure monthly active members, thread depth, and revenue attribution. These metrics tell you whether your community is healthy and worth the investment.
