Platform Architecture

Membership site

What is a membership site?

A membership site is a website or platform section that requires payment — typically a recurring monthly or annual subscription — to access its content, community, or resources.

The one-sentence definition: A gated content or community experience that earns recurring subscription revenue from members, not one-time course sales.

How membership sites differ from course platforms

Course platforms and membership platforms often overlap, but they start from different models:

DimensionCourse platformMembership site
Core productStructured curriculumRecurring access to content/community
Revenue modelOne-time purchase per courseMonthly/annual subscription
Primary metricCompletion rateChurn rate (members leaving)
Content formatVideo lessons in sequenceLibrary + community + live sessions
ExamplesTeachable, ThinkificCircle, Mighty Networks, Kajabi Communities

The three types of membership sites

1. Content membership — New content released weekly/monthly. Members pay for ongoing access to a growing library. Example: a fitness creator releasing new workouts monthly.

2. Community membership — Members pay for access to each other — the network, the peer group, the cohort. Content is secondary. Example: a mastermind group with weekly calls.

3. Hybrid (course + community) — A structured course is the entry point; the ongoing community is the reason members stay. Example: a business coaching programme with a course foundation and a live community for accountability.

The platform choice for membership-first businesses

If community recurring subscription is your primary business model (not a bolt-on to a course), the platform decision is: Circle at £89/mo, Mighty Networks at £39/mo, or Kajabi Growth at £127/mo if you also need the course infrastructure.

If your course is primary and membership/community is secondary, any of the major course platforms (Thinkific, Kajabi, Teachable) will suffice with their native community add-ons.

The critical mistake is choosing a course-first platform (Teachable, Thinkific) when community-first is your model. You’ll be fighting the product’s architecture from day one.

Pricing reality for membership sites

Membership site economics work when you have enough volume and low enough churn:

  • 200 members Ã- £20/mo = £4,000/mo MRR
  • If platform cost is £127/mo (Kajabi Growth), platform cost is 3.2% of revenue
  • If community churn is 5%/mo, you’re replacing 10 members/month to stay flat

The switching cost for members in a community site is the highest in this category. Once 800 members have their community history inside Kajabi Communities, migrating them to Circle is a hard restart — you lose their conversation history, connections, and engagement momentum.
