From LEGO to Peloton: How Communities Turn Customers into Marketers

What Glossier, BrewDog, and Gymshark Teach Us About Building Brands People Actually Belong To

There is a quiet shift happening in marketing – and it is not about channels, algorithms, or even budgets. It is about people.

Not audiences. Not segments. Not “users”.

Communities.

The brands that are winning today are not simply broadcasting messages. They are building spaces where people gather, contribute, and, crucially, feel like they belong. And when that happens, something remarkable occurs – marketing stops being something you do to people and starts becoming something people do for you.

This is the power of community.

What Do We Actually Mean by “Community”?

Community is one of those words that gets thrown around in marketing meetings until it loses all meaning – a bit like “authenticity” or “storytelling”.

But at its core, a community is simple:

  • A group of people with a shared interest, identity, or goal
  • A sense of belonging and participation
  • A platform or space (physical or digital) where interaction happens

What separates a community from an audience is interaction.

An audience listens.
A community responds, creates, challenges, and evolves.

Philip Kotler has long emphasised the shift from transactional marketing to relationship marketing. Communities take this one step further – they are not just relationships between brand and customer, but relationships between customers themselves, facilitated by the brand.

Why Communities Are So Powerful in Marketing

1. They Create Emotional Stickiness

People rarely feel loyalty to a product alone. They feel loyalty to what that product represents and who it connects them with.

When someone joins a running club organised by a brand, or contributes to a forum, or attends a fan event, they are no longer just buying – they are participating.

This taps directly into Maslow’s hierarchy of needs, particularly belongingness and esteem.

Once a brand becomes part of someone’s identity, price sensitivity tends to take a back seat.

2. They Turn Customers into Advocates

A strong community does something traditional advertising struggles with – it creates credible, peer-to-peer advocacy.

Cialdini’s principle of social proof comes into play here. When people see others like them engaging with a brand, recommending it, or creating content around it, it reduces perceived risk and increases trust.

In simple terms:

  • Ads say “we’re good”
  • Communities say “we’re good – and here’s thousands of people proving it”

3. They Generate Content at Scale

Communities are content engines.

User-generated content (UGC), reviews, discussions, memes, tutorials – these all extend the reach of a brand far beyond what a marketing team could produce internally.

And importantly, they feel more authentic.

George Orwell might not have been thinking about TikTok when he wrote about clarity and truth, but the principle applies: people trust what feels real, not overly polished corporate messaging.

Brands That Have Built Communities Brilliantly

Let’s look at some of the brands that have genuinely harnessed the power of community.

LEGO: Co-Creation at Its Finest

Few brands understand community quite like LEGO.

The LEGO Ideas platform allows fans to submit their own designs, with successful entries becoming official sets. This is not just engagement – it is co-creation.

What LEGO has done is blur the line between customer and creator.

  • Fans feel ownership over the brand
  • The brand taps into an endless stream of ideas
  • Successful products come pre-validated by the community

It is innovation, research, and marketing rolled into one.

Peloton: Fitness as a Shared Experience

Peloton did not just sell exercise bikes – it built a community around shared struggle, motivation, and progress.

Leaderboards, live classes, shout-outs from instructors – these are not features, they are community mechanics.

Members are not just working out; they are:

  • Competing
  • Supporting
  • Celebrating milestones together

This transforms a solitary activity into a social one, dramatically increasing engagement and retention.

Glossier: Built with the Customer, Not for Them

Glossier is often cited for good reason – but it earns its place here because of how fundamentally community-driven it is.

Before it was a product brand, it was a blog – Into The Gloss – where conversations with readers shaped product development.

Glossier listens, responds, and builds alongside its audience.

The result?

  • Products that reflect real customer needs
  • A loyal base that feels heard
  • Organic advocacy that money cannot easily buy

BrewDog: Turning Customers into Shareholders

Love them or loathe them, BrewDog’s “Equity for Punks” campaign is one of the most fascinating examples of community-driven marketing.

By allowing customers to buy shares in the company, BrewDog effectively turned its fans into stakeholders.

This created:

  • A sense of ownership
  • Strong emotional investment
  • A community with a vested interest in the brand’s success

It is difficult to overstate how powerful that is – your customers are no longer just buyers, they are investors and evangelists.

Gymshark: From Garage Brand to Global Movement

Gymshark’s rise was not built on traditional advertising. It was built on community.

Early on, the brand partnered with fitness influencers who were not just endorsers, but community leaders.

They hosted events, met fans, and created a sense of belonging around the brand.

Gymshark did not just sell gym wear – it created a culture.

Duolingo: Community Meets Chaos (In a Good Way)

Duolingo has taken a slightly different route – blending community with humour and internet culture.

Its social media presence encourages participation, memes, and user interaction.

The brand is not speaking at people – it is playing with them.

And crucially, the community responds in kind, creating a feedback loop of engagement.

How Marketers Can Harness the Power of Community

So how do you actually build one of these things without it feeling forced?

1. Start with a Shared Purpose

Communities form around something meaningful:

  • A goal (fitness, learning, sustainability)
  • An identity (creativity, rebellion, professionalism)
  • A problem to solve

If there is no clear reason for people to gather, they will not.

2. Create Spaces for Interaction

Communities need somewhere to live:

  • Online forums or groups
  • Social media platforms
  • Events and meet-ups
  • Dedicated apps or platforms

The key is not just presence, but facilitation.

A dormant Facebook group is not a community – it is a graveyard.

3. Encourage Participation, Not Just Consumption

Ask questions. Invite contributions. Highlight user content.

People need to feel like they are part of something, not just watching it.

This might include:

  • User-generated campaigns
  • Competitions or challenges
  • Co-creation opportunities

4. Reward and Recognise Members

Recognition is a powerful motivator.

Whether it is shout-outs, exclusive access, or tangible rewards, acknowledging contributions reinforces engagement.

Peloton’s instructor shout-outs are a perfect example – small gesture, big impact.

5. Let Go of Control (A Little)

This is often the hardest part for brands.

Communities are not entirely controllable. They evolve, develop their own tone, and sometimes go in unexpected directions.

But that is also where their power lies – they feel real.

Trying to over-manage a community often kills it.

The Risks (Because It’s Not All Sunshine)

Communities are powerful, but they are not without challenges:

  • Negative sentiment can spread quickly
  • Expectations for responsiveness are high
  • Authenticity is constantly tested
  • They require ongoing effort, not one-off campaigns

In other words, you cannot “launch a community” and move on. It is a long-term commitment.

Final Thought

There is a tendency in marketing to chase the next shiny tactic – the newest platform, the latest AI tool, the cleverest campaign.

But communities are not new. They are fundamental.

People have always gathered around shared interests and identities. The difference now is that brands can play a role in facilitating those gatherings at scale.

And when they get it right, something interesting happens:

The brand stops being the centre of attention.

The community becomes it.

TL;DR

  • Communities turn passive audiences into active participants
  • They drive loyalty, advocacy, and scalable content creation
  • Brands like LEGO, Peloton, Glossier, BrewDog, Gymshark, and Duolingo show different ways to build them
  • Success comes from shared purpose, participation, and letting go of control
  • Communities are not campaigns – they are long-term assets that, when nurtured properly, can outperform traditional marketing

And perhaps the simplest way to think about it:

If your customers would miss each other when your brand disappears, you have built a community.

If they would not notice – you have built an audience.
