Not a gimmick

Things like referral bonuses or “more members = more discount” are engineered incentives, not true network effects. A real network effect is a natural phenomenon where value actually increases as more people participate.

Five properties of a true network effect

A network effect you can rely on must have all of these:

• Shared behavior gets better with more people – there is a central activity that becomes more valuable as more people do it.

• Behavior is visible – others can see the participation and density (e.g. group size, activity).

• Sharing raises status – talking about or inviting others into it makes the sharer look good, not embarrassed.

• Feedback loop exists – more participants make the experience better, which attracts more participants, which makes it better again.

• Reward grows with scale – the upside for each individual (attention, connection, recognition, usefulness) increases as the network grows.

Design starting from the desired feeling

You choose the shared behavior by asking:

• What is my core patient group’s desired feeling?

• What ongoing activity would help them move toward that feeling, specifically within dentistry / oral health?

  For you (Pharo), this might be a marketing and practice-growth community. For a cosmetic practice, it might be a hub around aesthetics, confidence, or self-care tied to teeth and smile.

Make it adjacent to your practice, not a gated patient-only club

The hub is not “only for patients” or a direct sales room. It is a playground / safe space you own and control, focused on that shared behavior and desired feeling, aligned with your industry. It sits next to the practice, not inside the operatory.

The hub + early adopters = the engine

• You build a hub that meets all five criteria, then fill it with early adopters who already resonate with your worldview and desired feeling.

• As they participate, the network effect kicks in. It becomes more valuable, so they have a selfish reason to bring in friends and peers.

• New mainstream members enter as the minority inside a space defined by early adopters.

How this pulls the mainstream

Inside that hub, the early adopters’ behavior is visible culture. The mainstream comes in and observes how they think, act, and relate to health and treatment. That culture loop gradually normalizes proactive, higher-status dental behaviors and aligns them with your practice’s story.

Your job

Your task is to invent a shared activity around your patients’ desired feeling, then check it against the five properties. If it fits, and you seed it with early adopters, you’ve created a genuine network-effect hub that magnetically attracts and shapes the mainstream over time.
