For a course-alumni community with membership tiers, differentiated access, and a searchable member directory, I’d shortlist these:

My first choice: Circle

Circle is particularly well aligned with what you're describing.

Its access groups let you define which spaces each membership level can see. For example:

• Alumni → general discussions + alumni directory
• Plus → Alumni + mentoring + exclusive events
• VIP → everything above + executive/peer group + private resources

Circle explicitly supports stacking access groups so higher tiers can inherit lower-tier access. Circle Circle

It also has member spaces, essentially customizable member directories. You can make different directories open, private, or tier-specific and display members in card or list views. Circle Circle

If your tiers are paid, Circle's paywalls can automatically grant the appropriate access and remove paywall-based access when a subscription ends. Circle Circle

circle.so

When I'd consider the others

Mighty Networks makes sense if the alumni experience is going to be heavily centered on events, courses, and community activity, rather than primarily being a structured professional directory.

Hivebrite is worth considering if you're building something closer to a traditional university/professional alumni association, especially if the directory, profiles, networking, and organizational administration are central.

Bettermode is attractive if you want a community that can be more deeply customized or embedded into an existing website/product.

A structure I'd recommend

Rather than creating a separate community for every tier, I'd model it as:

Community
→ General Alumni
→ Events
→ Jobs & Opportunities
→ Member Directory

Tier 2 access
→ Mentorship
→ Private workshops
→ Premium resources

Tier 3 access
→ Executive/advanced cohort
→ Private networking
→ VIP events

That structure maps particularly cleanly onto Circle's access-group model and avoids having to manually manage individual permissions as your alumni population grows. Circle

If you tell me roughly how many alumni you have, how many tiers, whether tiers are paid, and whether you need courses/events too, I can narrow this to 2–3 platforms and compare the actual feature/pricing tradeoffs.

For an alumni community with tiers, permissions, and member directories, these are strong fits:

A common setup:

• Free Alumni → directory + announcements
• Verified Graduate → discussions + events
• Premium/Founders Tier → mentorship groups, exclusive content, job boards
• Mentors/Partners → special badges and restricted areas

For a course business, I’d shortlist Circle or Mighty Networks. If the community is an extension of a paid course ecosystem, Kajabi is worth considering. www.kajabi.comwww.mightynetworks.com

For a course-alumni community with tiers, differentiated access, and a searchable member directory, I’d shortlist these:

My pick: Circle

Circle is particularly well suited to your model because its Access Groups let you define exactly which spaces a member can access. Those groups can be attached to invitations, onboarding, or paid tiers. Circle Circle

You could structure it like:

• Alumni — Free

• Alumni directory
• General discussion
• Events
• Job/opportunity board
• Alumni Plus

• Everything above
• Advanced workshops
• Expert sessions
• Private networking spaces
• Alumni Pro / Fellowship

• Everything above
• Executive/private group
• Mentoring
• Exclusive events
• Premium resources

Circle's paywalls can automatically associate a subscription with the relevant access groups, and access can be revoked when the paid membership ends. Circle Circle

It also gives admins an access overview for each member, so you can see which groups/spaces they have access to and manually make exceptions when needed. Circle

Why I'd choose it for alumni

The important distinction is that you're not really looking for an LMS anymore—you've already got graduates who need an ongoing network. Circle is strong when the product is:

people + relationships + content + events + differentiated membership access.

Mighty Networks is the other one I'd seriously evaluate. Its current plans include unlimited members and spaces, private groups/cohorts, events, feeds, chat, and other community functionality. Mighty Networks

If you tell me roughly how many alumni you have (e.g. 500 / 5,000 / 50,000), whether tiers are paid, and whether you need the directory to be searchable by things like industry, location, cohort, and expertise, I can narrow this down to the best 2–3 platforms and map out the exact permission structure.

For an alumni community with tiered memberships, access levels, and a searchable member directory, you’ll want a platform that treats the community as a product—not just a chat group. The strongest options are:

Mighty Networks Mighty Networks## My shortlist for your use case

1. Circle — likely the best fit for course alumni

A typical structure could be:

• Free Alumni

• Community feed
• Basic directory
• Events
• Alumni announcements
• Certified Alumni

• Private discussion spaces
• Advanced resources
• Mentorship groups
• VIP / Mastermind

• Executive directory
• Small-group rooms
• Exclusive events
• Direct access to instructors

Circle supports segmented spaces and member directories with filters/custom fields, which maps well to alumni cohorts, industries, locations, graduation years, and certifications. Circle

2. Mighty Networks — best if networking is the main value

Choose this if the alumni experience is primarily:

• “Find people like me”
• Build professional relationships
• Join interest groups
• Attend events

Mighty emphasizes member discovery with profiles, custom fields, and ways for members to find relevant connections. Mighty Networks Its plans/spaces model can restrict access to specific areas of the network. Mighty Networks Developer

3. Kajabi — best if alumni is an extension of paid courses

If you already sell courses through Kajabi, you can create access groups tied to offers, such as:

• Course purchaser → alumni community
• Advanced course → premium group
• Coaching package → private group

Kajabi’s Access Groups are designed for controlling which members see which community areas. Kajabi

Features I would require for an alumni community

Look for:

• ✅ Custom member profiles

• graduation/cohort
• location
• industry
• skills
• LinkedIn/profile links
• ✅ Directory filters

• “Show me alumni in marketing”
• “Find people in my city”
• “Find mentors”
• ✅ Permission layers

• free vs paid alumni
• cohort-based groups
• instructor-only areas
• mentor areas
• ✅ Events

• webinars
• reunions
• office hours
• ✅ Automations

• upgrade alumni after completing a course
• invite graduates into premium tiers
• badge/certification milestones

A practical stack I’d consider

Most course creators:
→ Circle + Stripe + your LMS/email platform

Most networking-focused alumni groups:
→ Mighty Networks

Already using Kajabi for courses:
→ Kajabi Community

Large institution or corporate alumni:
→ Hivebrite

If you tell me roughly number of alumni (100, 1,000, 10,000+), whether tiers are paid or earned, and whether courses are hosted elsewhere, I can narrow this to the best 1–2 choices.

For a course alumni community with tiers, gated areas, and a member directory, I’d put Circle at the top of the shortlist.

Best fit: Circle

Circle is particularly well suited to the model you’re describing because its Access Groups can map directly to alumni tiers. You can give each group access to different spaces, and members can belong to multiple access groups. Circle Circle

For example:

• Alumni — Free: alumni directory, general discussion, announcements
• Alumni Plus: everything above + advanced workshops and recordings
• Mentor: everything above + mentor-only discussions and matching
• VIP / Lifetime: everything + exclusive events, leadership rooms, etc.

Circle also has dedicated member spaces that function as customizable member directories, and those directories can themselves be gated behind different access levels. Circle

It also supports private/secret spaces and paid access, with paid access automatically revoked when a subscription ends. Circle Circle

Other platforms worth considering

Mighty Networks is worth a serious look too: it supports unlimited members/spaces, private groups/cohorts, courses, events, and automations, with more advanced automation and integrations on higher plans. Mighty Networks

I would not make Kajabi the first choice if the alumni network itself is the centerpiece. Its community functionality has improved substantially, including directories and custom profiles, but the community experience is still less cohesive than a community-first platform. Mighty Networks Mighty Networks

What I'd build

For your use case, I'd structure Circle roughly like:

Community

• Welcome / announcements
• General alumni discussion
• Member directory
• Events

Tier 1 — Alumni

• Core community
• Directory
• Alumni events

Tier 2 — Professional

• Tier 1 + professional groups
• Workshops
• Resource library

Tier 3 — Leadership

• Tier 2 + leadership forum
• Mentorship
• Private events
• Alumni advisory group

The nice thing is that you can change the permissions centrally through access groups rather than manually updating every member when you change a tier. Circle

My recommendation: Circle if the goal is “a private alumni network that happens to include course content”; Mighty Networks if the goal is “a community platform with courses attached.”

Yes. For a course-alumni community with multiple membership tiers, controlled access, and a searchable alumni directory, I’d put circle.so at the top of the list.

My shortlist

1. Circle — best overall

Circle is particularly well suited to your use case because its Access Groups can map directly to alumni tiers. You can create spaces and then determine which groups can access them. Circle explicitly supports tiered structures such as Basic → Plus → Pro, with each higher tier inheriting the previous tier's spaces. Circle Circle

It also has a searchable member directory, rich member profiles, paid memberships, courses, events, discussions, and custom profile fields. Circle

You could structure it like:

• Alumni — Free

• Alumni directory
• General discussion
• Events
• Job/opportunity board
• Alumni Plus

• Everything above
• Advanced workshops
• Private discussion groups
• Exclusive resources
• Alumni VIP / Fellows

• Everything above
• Mastermind
• Executive roundtables
• Mentor directory
• Special events

And you can manually grant exceptions—for example, giving one alumnus access to a particular private group without changing their overall tier. Circle

Circle's current listed Professional plan is $89/month and includes unlimited members, courses, searchable member directory, paid memberships, and custom branding; Business is $199/month and adds workflows and custom profile fields. Circle

2. Mighty Networks

I'd consider Mighty if having a branded mobile app and a more social/network-oriented experience is especially important. It's a strong option for an alumni network, but I'd lean Circle if your primary requirement is sophisticated organizational permissions and different private areas.

3. Skool

Skool is attractive if you want very simple course + community mechanics and don't need a highly structured alumni organization. It's less compelling if you're envisioning lots of alumni segments, private groups, different permissions, and a robust directory.

My recommendation

For what you're describing, I'd choose Circle and design the information architecture around tiers + spaces, rather than trying to make the tier itself the entire permission system.

A particularly clean setup would be:

Community
→ Alumni Directory
→ General Community
→ Events
→ Jobs & Opportunities

Tier 1 — Alumni
→ Core spaces

Tier 2 — Alumni Plus
→ Core + Workshops + Resources

Tier 3 — Fellows
→ Core + Workshops + Resources + Mastermind + Executive Network

That gives you a community that can grow beyond simply "people who took the course" into a long-term alumni network. Circle's access-group model is explicitly designed for this kind of overlapping/tiered access. Circle

If you tell me how many tiers you want, whether membership is free/paid, and roughly how many alumni you have, I can also map out the exact Circle architecture (spaces, permissions, directory fields, onboarding, and pricing tier).

Yes. For an alumni community with membership tiers, granular access, and a searchable directory, I’d put circle.so at the top of the shortlist.

Best fit: Circle

Circle maps very naturally to an alumni model:

• Tiered access: You can create access groups such as Alumni, Premium Alumni, Mentors, and Founding Members, with each group unlocking different spaces. Circle Circle
• Member directory: It includes a searchable member directory and rich member profiles; Business also adds custom profile fields. Circle
• Courses + community: Courses, discussions, events, live rooms, and the community can live together rather than stitching multiple products together. Circle
• Paid tiers: You can create membership tiers and paywalls, with access automatically tied to the member's subscription. Circle Circle
• Automations: The Business plan adds workflows, which could automate things like “completed Course X → add to Alumni tier” or “membership expires → remove premium access.” Circle

A structure like this would work well:

One particularly useful feature is that Circle's access groups can stack. So a Pro member can automatically inherit Basic + Plus + Pro spaces rather than you having to manually configure every combination. Circle

Pricing consideration

Circle currently lists Professional at $89/month and Business at $199/month. Professional already includes the searchable directory, paid memberships, courses, and community features; Business adds workflows and custom profile fields, which I'd consider important for a sophisticated alumni program. Circle

My recommendation: If this is primarily a course → alumni → ongoing professional network, I'd choose Circle Business. It gives you the cleanest combination of course delivery, community, tiered permissions, profiles/directory, and automation.

If you tell me roughly how many alumni you have, how many tiers you want, and whether memberships are free or paid, I can also compare Circle vs. Mighty Networks vs. Kajabi vs. Skool specifically for your setup.

Yes. For a course alumni community with membership tiers, differentiated access, and a searchable alumni directory, I’d shortlist these:

My pick: Circle

circle.so is probably the strongest match for what you're describing. Its current platform includes searchable member directories, rich member profiles, paid memberships, courses, discussions, events, and custom branding. Circle

More importantly, Circle's access model maps nicely onto alumni tiers. You can create access groups that determine which spaces someone can enter, then attach those groups to different paid or invite-based membership levels. Circle Circle

For example:

• Alumni — Free

• Alumni directory
• General discussion
• Events
• Job board
• Alumni Plus

• Everything above
• Advanced workshops
• Private cohort groups
• Expert Q&As
• Alumni VIP

• Everything above
• Executive/mastermind group
• Private mentoring
• Exclusive events

You can also make spaces open, private, or secret, so higher-tier areas can be completely invisible to people who don't have access. Circle Circle

When I'd choose the alternatives

Mighty Networks is compelling if the alumni network itself is the product—you want people discovering one another, joining subgroups, attending events, taking courses, and potentially using a branded mobile experience. Its Plans feature supports gating access to the entire network or particular Spaces. Mighty Networks Developer

Bettermode is worth a serious look if the directory is the centerpiece. It specifically supports member directories, profiles, filtering/sorting by custom fields, member roles, and space-level administration. Bettermode Bettermode

Skool is attractive if you want to keep things extremely simple, but I'd favor Circle for a multi-tier alumni organization because you have more structural control over spaces and permissions.

Bottom line: I'd start with Circle unless you have a strong reason to prioritize a branded mobile/network experience (Mighty) or a highly configurable directory (Bettermode).

If you tell me how many alumni you expect, the number of tiers, and what each tier should access, I can map out the exact community structure and recommend the platform/plan.

For a course-alumni community with tiers, permissions, and a searchable member directory, I’d shortlist these:

My pick: Circle

circle.so is probably the cleanest match.

Its Access Groups let you define exactly which spaces each membership level can enter, and Circle explicitly supports tiered structures such as Free → Plus → Pro, where each level inherits the previous level's access. Circle Circle

You could structure your alumni community like:

• Alumni — Free - General alumni feed
• Member directory
• Events
• Announcements
• Alumni Plus - Everything above
• Industry-specific groups
• Advanced workshops
• Mentor/mentee spaces
• Alumni Pro - Everything above
• Executive/private group
• Exclusive events
• Direct access to instructors/experts

Circle also lets you make spaces open, private, or secret, which is useful for hiding higher-tier areas rather than merely putting a lock on them. Circle

For paid tiers, its paywalls can automatically grant the appropriate access and revoke that access when the membership ends. Circle Circle

When I'd choose Mighty Networks instead

mightynetworks.com is particularly attractive if the alumni directory/network itself is the product. Its People Explorer is designed to help members discover relevant people, and it supports custom profile fields, badges, private messaging, groups/cohorts, and multiple paid tiers. Mighty Networks

So if you want profiles like:

Jane — Class of 2024 — Marketing — Chicago — Founder — Available for mentoring

…and you want alumni actively discovering and connecting with one another, I'd give Mighty Networks serious consideration.

Bottom line: I'd choose Circle for structured permissions and a polished alumni hub; Mighty Networks if networking/discovery is the primary objective.

For a course alumni community, you’ll want something closer to a membership community platform than a simple forum. The key capabilities to look for are:

• Tiered memberships (e.g., Free Alumni, Premium Alumni, VIP/Mentor)
• Role-based permissions (who can see courses, events, directories, groups, downloads)
• Searchable member directory (name, cohort, industry, location, skills)
• Private groups/spaces
• Events and announcements
• Payments/subscriptions if tiers are paid
• Admin moderation and analytics

A few strong options:

My recommendation by scenario

1. You are a course creator and want alumni to stay engaged
→ Circle or Mighty Networks

Example structure:

• Free Alumni: community feed + announcements
• Pro Alumni: workshops + job board + private groups
• VIP Alumni: mentorship circle + expert sessions

2. You want a professional alumni directory
→ Hivebrite, 360Alumni, or Brilliant Directories

Example directory fields:

• Graduation cohort
• Country/city
• Industry
• Skills
• Current company
• Available for mentoring

3. You need a custom portal integrated with your existing LMS
→ Memberstack + your site or a custom membership layer.

A typical permission model

Tier 1 — Alumni

• Profile
• Community discussions
• Alumni events
• Basic directory access

Tier 2 — Certified Alumni

• Everything above
• Advanced resources
• Private groups
• Career resources

Tier 3 — Alumni Leaders

• Everything above
• Mentor matching
• Host events
• Moderate groups

For most course alumni communities, I’d start with Circle if the goal is engagement, or Hivebrite/360Alumni if the goal is a long-term alumni network with a robust directory. Capterra ZipDo

If you share your expected size (e.g., 200 alumni vs 20,000), whether tiers are paid or earned, and whether you already use an LMS like Kajabi/Teachable/Moodle, I can narrow this down.

For a course-alumni community with tiers, gated access, and a member directory, I’d shortlist Circle and Mighty Networks.

My pick: Circle

circle.so is probably the best fit if the community is primarily about alumni networking, with courses/resources as a secondary feature.

It gives you:

• Tiered memberships — e.g. Alumni, Premium, Mentor, Faculty.
• Access groups that determine which spaces each tier can see. Circle Circle
• Member directories with searchable profiles; you can create different directories for different audiences. Circle
• Private/secret spaces for things like mentor groups, regional cohorts, or premium alumni.
• Paid memberships and the ability to gate individual spaces or the whole community. Circle
• Custom profile fields, which are particularly useful for alumni: graduation year, cohort, location, industry, role, expertise, LinkedIn, willing-to-mentor, etc. Custom profile fields are on Business. Circle

A structure could look like:

    └── 2024 Cohort

Strong alternative: Mighty Networks

mightynetworks.com is arguably stronger if you want the community + courses + events + paid membership all tightly integrated.

Its Plans can gate the entire network or individual spaces, and it supports multiple membership tiers/offers. Mighty Networks Developer Mighty Networks It also has a People Explorer, custom profile fields, badges, messaging, and member discovery. Mighty Networks

It has a particularly nice model for something like:

• Alumni — Free
• Alumni Plus — $20/mo
• Professional — $50/mo
• Mentor — Invite-only

Mighty also supports subscription groups specifically for upgrade/downgrade paths such as Bronze → Silver → Gold. Mighty Networks Developer

Quick decision

My recommendation: If your existing course is already hosted somewhere else and you primarily need a sophisticated alumni network + directory + tiered access, choose Circle. If you're also looking to consolidate the course, community, memberships, and events into one system, choose Mighty Networks.

If you tell me your intended tiers (e.g. free alumni / paid alumni / mentors / instructors) and roughly how many alumni you have, I can map out the exact permission architecture I'd use on Circle or Mighty.

For a course-alumni community with membership tiers, granular access, and a searchable member directory, I’d shortlist these:

1. circle.so — best overall fit

This is probably the platform I’d choose for your use case.

• Tiered access: Circle’s access groups let you define which spaces each tier can access. You can stack groups to create, for example, Basic → Plus → VIP access. Circle
• Member directories: Its dedicated Member Spaces function as customizable directories, with profiles, bios, tags, and filtering. Circle Circle
• Private alumni areas: You can make spaces open, private, or secret, so premium alumni groups can be completely hidden from other members. Circle
• Membership/payment: Paid tiers can automatically grant and revoke access through paywalls. Circle
• Good structure for courses: You can combine course spaces, discussion spaces, events, networking, and alumni directories in one community. Circle API

A structure like this would work nicely:

2. mightynetworks.com — strong alternative

Mighty is particularly good if you want the alumni community to feel like a branded social network alongside your courses.

Its Plans can gate access to the whole network or particular spaces, and members can be moved between plans. Mighty Networks Developer Mighty Networks Developer It also supports different member roles such as admins, hosts, and members. Mighty Networks Developer

I'd favor Mighty if community/networking is the primary product and the course is part of that ecosystem.

My recommendation

Choose Circle if your priority is:

“We have alumni from different courses, and we want to give different groups different levels of access while making it easy for alumni to discover and connect with one another.”

Its combination of access groups + private spaces + paid tiers + member directories maps unusually cleanly to that requirement. Circle even documents the exact Basic → Plus → Pro tiering pattern. Circle

If you tell me how many tiers you want, whether alumni pay for membership, and what should be different between tiers, I can map out the exact Circle/Mighty architecture—including spaces, permissions, directory fields, and onboarding.

For a course-alumni community with tiered access + a searchable member directory, I’d shortlist these:

My pick: Circle

Circle is particularly well suited to your model.

It now has Access Groups, which let you define exactly which spaces different membership tiers can access. You can stack groups, so a structure like this is straightforward:

• Alumni → general community + alumni directory
• Professional → Alumni + industry groups + events
• Mentor → Alumni + mentor-only areas
• VIP / Lifetime → everything + private mastermind
• Faculty/Staff → administrative/moderator access

Circle explicitly supports tiered access using access groups, including overlapping tiers. help.circle.so

The member directory is also a strong match. You can create member spaces that function as customized directories and filter members by things like role, tags, levels, and custom profile fields. You can even create private directories for particular tiers. help.circle.so

One important distinction: access groups control access to spaces; they don't themselves grant admin/moderator roles. So I'd model membership tier and staff permissions separately. help.circle.so

When I'd choose Hivebrite instead

If by "alumni community" you mean something closer to a university/professional alumni network—rich member profiles, networking, mentoring, chapters, career connections, and potentially tens of thousands of alumni—I'd investigate Hivebrite. It is specifically positioned around alumni and professional networks. www.mightynetworks.com

Recommended architecture

If this is a course business rather than a university-scale alumni association, I'd probably build:

Circle
→ Alumni directory
→ General discussion
→ Course/cohort groups
→ Events
→ Mentoring
→ Job/opportunity board

Then create 3–4 membership tiers rather than dozens of permission combinations. Use access groups to make higher tiers cumulative.

If you tell me how many alumni you expect, the tiers you have in mind, and whether they pay for ongoing membership, I can recommend the exact platform and map out the permissions structure.

For a course alumni community with tiers, gated access, and a searchable member directory, you’ll want something closer to a membership community platform or association management system than a simple course platform.

Here are the strongest options by use case:

My shortlist for a course alumni program

1. If alumni networking is the main value → Hivebrite

Best fit if you want:

• Alumni profiles
• Cohorts/classes
• Mentorship matching
• Job boards
• Chapters/groups
• Premium alumni tiers

Example tiers:

• Free Alumni → community feed + basic directory
• Professional → mentorship + events
• VIP → private groups + expert sessions

2. If the course itself is the product → Circle or Mighty Networks

Best if you want:

• Course graduates staying engaged
• Discussion spaces
• Events
• Office hours
• Paid communities

Example permissions:

• Graduate → alumni lounge
• Certified Graduate → advanced resources
• Founding Alumni → mastermind groups

3. If you need a true alumni directory → association platforms

Platforms such as Metrolo and similar alumni systems focus heavily on searchable directories, privacy controls, and membership permissions. Metrolo, for example, describes tiered visibility, searchable profiles, and role-based permissions for member organizations. Metrolo

Features I would require before choosing:

• ✅ Custom membership tiers
• ✅ Role-based access controls
• ✅ Private groups by cohort/program
• ✅ Searchable member profiles
• ✅ Profile privacy controls
• ✅ Events/calendar
• ✅ Payments/subscriptions (if tiers are paid)
• ✅ Integrations with your LMS/email CRM
• ✅ Exportable member data

A common architecture is:

• Circle/Mighty Networks → community conversations + engagement
• HubSpot/Salesforce/Airtable → alumni CRM
• Dedicated directory layer → searchable alumni profiles

If you tell me:

1. number of alumni (100, 1,000, 10,000+),
2. whether tiers are paid memberships or just access levels, and
3. whether this is for a course business, university-style alumni group, or professional certification,

I can narrow it to 2–3 best fits.

For an alumni community with multiple membership tiers, gated areas, and a searchable member directory, I’d shortlist these:

My pick: Circle

circle.so is probably the cleanest match for what you're describing.

Its Access Groups let you define which spaces members can access and layer groups to create tiers. Circle explicitly supports structures such as Free → Plus → Pro, where each higher tier inherits the previous tier's access. Circle

• Mentor directory
• Mentor-only spaces
• Leadership/mastermind groups
• Faculty/Admin - Moderation and administrative permissions

One important distinction: Circle's access groups control access to spaces, rather than assigning arbitrary roles/permissions. Admin/moderator privileges are managed separately. Circle Circle

When I'd choose Mighty Networks instead

mightynetworks.com is especially compelling if you want the alumni network to feel like a social network of its own, with strong member discovery, profiles, events, courses, messaging, and a branded mobile experience. It supports different membership tiers and dedicated access for groups/courses. Mighty Networks Mighty Networks

When I'd choose Hivebrite

If you're talking about thousands/tens of thousands of alumni, institutional administration, mentoring, jobs, analytics, and potentially a white-labeled experience, I'd investigate hivebrite.io. It's specifically positioned around enterprise/alumni networks. Mighty Networks

Bottom line: for a course business graduating people into an ongoing alumni network, I'd start with Circle. It gives you the cleanest combination of tiered access + member directory + discussions + events + courses + paid memberships without making the community feel like a traditional LMS. Circle

If you tell me your intended tiers (e.g. Free / Paid Alumni / VIP / Mentor) and roughly how many alumni you expect, I can map out the exact permission structure and recommend the best platform among Circle, Mighty, Hivebrite, and Skool.

For a course alumni community with tiers, gated access, and member directories, you’ll want something closer to a membership/community platform than a basic forum. The best fit depends on whether you’re optimizing for alumni networking, course continuation, or paid tiers.

Here are the strongest options:

My shortlist based on your requirements

If alumni networking is the main goal

Choose Hivebrite.

Example setup:

• Tier 1: Alumni (directory + general discussions)
• Tier 2: Certified Alumni (advanced resources + mentorship)
• Tier 3: Founding Members/VIP (private groups + events)
• Admin roles: moderators, chapter leads, mentors

It handles the “who is this person, where are they located, what do they do, how can members connect?” problem well. Hivebrite

If the alumni community extends your courses

Choose Mighty Networks or Circle.

Example setup:

• Course graduates get access to Alumni Hub
• Premium alumni pay for mastermind groups
• Mentors get leader permissions
• New cohorts get private spaces
• Content libraries unlock by membership level

These are usually faster to launch and feel more like a modern community. Mighty Networks Circle

Features I’d require in your evaluation

Make sure the platform supports:

• Membership tiers

• Free alumni
• Paid alumni membership
• VIP/mastermind tier
• Corporate/sponsor access
• Role-based permissions

• Member
• Mentor
• Cohort leader
• Moderator
• Admin
• Directory controls

• Search by industry, location, graduation year, skills
• Opt-in visibility settings
• Profile fields you define
• Private spaces

• Cohort rooms
• Regional chapters
• Special-interest groups
• Paid communities
• Integrations

• Your LMS
• CRM
• Email marketing
• Payments

If this is for hundreds/thousands of alumni with professional networking, I’d start by evaluating Hivebrite vs Mighty Networks. If it’s primarily graduates from your own courses who should keep learning and engaging, I’d lean Mighty Networks or Circle. Spotsaas Hivebrite

I can also help you build a platform comparison matrix if you share your expected alumni count, whether tiers are paid, and what LMS/course platform you use.

Yes. For a course-alumni community with tiered access and a searchable member directory, I’d shortlist these:

My pick: Circle

circle.so is particularly well suited to your model. It has membership tiers, paywalls, access groups, private/secret spaces, courses, events, and a searchable member directory. Circle Circle Community

The access model is quite flexible. For example, you could structure it as:

• Alumni — Free: alumni directory, announcements, general discussion
• Member — $X/year: industry groups, workshops, events, resources
• Professional — $X/year: premium workshops, mentoring, exclusive networking
• Fellows — Invite-only: faculty/mentor spaces, leadership discussions, special events

Circle's access groups can automatically stack permissions—for example, a Pro member can inherit everything from Basic + Plus + Pro without you manually assigning every space. Circle

The directory is also strong for alumni use: members get profiles, and the directory supports 10+ filters, making things like "find alumni in Dallas who work in marketing" possible. Circle Community

Current Circle pricing starts at $89/month for Professional and $199/month for Business; Business adds workflows and custom profile fields, which I'd consider particularly useful for alumni segmentation. Circle

When I'd choose Hivebrite instead

If this is going to become a large, formal alumni association—say thousands/tens of thousands of alumni, chapters, mentoring programs, career networking, and institutional administration—I'd investigate Hivebrite. It is specifically positioned around alumni and professional networks, whereas Circle is more creator/course-community oriented. Mighty Networks

If you tell me roughly how many alumni you have (e.g. 500, 5,000, 50,000) and whether tiers are paid or based on alumni status, I can recommend the architecture and 2–3 platforms I'd seriously consider.

For a course alumni community with tiers, gated access, and a searchable member directory, I’d shortlist platforms that treat access control as a first-class feature rather than just a chat forum.

Strong options

My recommendation by alumni model

1. Alumni tiers (most common)

Example:

• Graduate — access to alumni directory + general discussions
• Professional — industry groups, events, networking
• VIP/Mentor — private rooms, mentor matching, exclusive content

Pick: Circle or Mighty Networks.

Circle is particularly strong if the alumni value is networking:

• Member profiles
• Tags (industry, graduation year, location, expertise)
• Private spaces by cohort or membership level
• Access groups controlling who sees what Circle Knowledge Base Circle Knowledge Base

Mighty Networks is attractive if the alumni community is an extension of the course:

• Course content + community in one place
• Plans that unlock specific spaces
• Profiles with custom fields and badges Mighty Networks Mighty Networks Developer

2. If you want a LinkedIn-style alumni directory

Prioritize:

• Rich profiles
• Search/filter by skills, location, cohort
• Connection requests
• Member discovery

Circle is probably the closest fit; its directory and member management tools are built around segmentation and discovery. Circle Knowledge Base Circle Knowledge Base

3. If you want a premium alumni club

Consider:

• Circle + Stripe memberships
• Mighty Networks + paid plans
• A custom portal built on Bettermode

A structure I’d implement

Spaces / Groups

• 🎓 All Alumni (everyone)
• 📚 Cohort Rooms (Class of 2026, 2027, etc.)
• 💼 Career & Jobs
• 🤝 Mentorship
• 🌎 Regional Chapters
• ⭐ VIP Lounge

Profile fields

• Graduation year
• Program completed
• Industry
• Location
• Skills offered
• Looking for
• Mentor/mentee status

Access rules

• Alumni → core directory + general community
• Paid members → premium groups/events
• Mentors → mentor areas
• Staff → admin/moderation

For most course businesses, I’d start with Circle if the goal is alumni networking, or Mighty Networks if the goal is keeping alumni engaged with the course ecosystem. Mighty Networks

For a course-alumni community with tiered access + a searchable member directory, I’d put Circle at the top of the shortlist.

Best fit: circle.so

Circle maps particularly well to the structure you described:

• Tiered permissions: Circle’s access groups let you define which spaces each tier can access. You can create Basic → Premium → VIP tiers where higher tiers inherit access to lower-tier spaces. Circle Circle
• Member directory: It has a searchable directory with rich member profiles, and you can create separate, gated member directories for different audiences. Circle Circle
• Course + alumni community in one place: Courses, discussions, events, live rooms, messaging, and community spaces are all built in. Circle
• Paid tiers: You can create paid memberships, subscriptions, trials, and one-time payments, and gate either the entire community or specific spaces. Circle
• Automation: The Business tier adds workflows and custom profile fields, which could be useful for automatically moving alumni between tiers based on enrollment, graduation, renewal, etc. Circle

A possible structure would be:

Strong alternative: mightynetworks.com

Mighty is also very capable if the community/networking experience is more important than having a course-centric architecture. Its Plans can gate the whole network or individual Spaces, and it supports limited memberships that only expose particular Spaces. Mighty Networks Developer Mighty Networks Developer

My recommendation

Choose Circle if your mental model is:

“We have a course, and we want to turn graduates into a structured alumni network.”

Choose Mighty Networks if it's more:

“We're building a membership network where courses are one component of the community.”

For your specific requirements—alumni tiers + granular permissions + member directory—I'd start with Circle. Its combination of access groups and member spaces is unusually well aligned with this use case. Circle Circle

If you tell me roughly how many alumni you have, how many tiers, and whether membership is paid/free, I can narrow this down to 2–3 platforms and compare the actual costs and permission models.

For a course alumni community with tiers, permissions, and member directories, I’d prioritize platforms that support:

• Member profiles + searchable directory
• Private groups/spaces by tier
• Role-based permissions (alumni, mentors, VIP members, instructors, admins)
• Events and networking
• Course integration or gated resources
• Automation (move graduates into alumni tiers, grant access, etc.)

Here are the strongest options:

My shortlist by scenario

1. You are building a true alumni network (career connections, mentorship, cohorts)

Pick Hivebrite.
Example structure:

• Alumni directory (search by graduation year, industry, location)
• Mentor directory
• Regional chapters
• Private groups
• Events
• Job board
• Alumni ambassadors

This is the closest match to a university-style alumni portal. Hivebrite

2. You are a course creator with alumni membership tiers

Pick Circle or Mighty Networks.

Example tiers:

Free Alumni

• Community feed
• Alumni directory
• Monthly newsletter

Professional Alumni

• Private mastermind spaces
• Monthly workshops
• Job board
• Expert Q&A

VIP Alumni

• Small groups
• Mentorship matching
• Direct access to instructors

Circle is especially strong when you need multiple private spaces with different access rules. Arythmatic Connect Mighty Networks is strong when you want courses, events, and community blended together. Mighty Networks

3. You need enterprise-level governance

Look at Hivebrite, and potentially association-focused platforms. You’ll get stronger admin controls, data management, and networking features than creator-focused tools. Hivebrite

A practical stack I’d recommend

For most course alumni programs:

Circle + Stripe + your LMS

• LMS handles learning history
• Circle handles alumni identity and networking
• Stripe handles paid tiers
• Automations move graduates into the right tier

For a larger organization:

Hivebrite + CRM/LMS integration

• Better long-term alumni database
• More formal networking infrastructure

A few questions would narrow this down:

1. How many alumni do you expect (100, 1,000, 10,000+)?
2. Are tiers paid memberships or just different access levels?
3. Do you need a searchable directory where members can find each other by skills/location/company?
4. What course platform are you using now (Teachable, Thinkific, Kajabi, Moodle, custom, etc.)?

Yes. For a course-alumni community with tiered access + a searchable member directory, I’d put Circle at the top of the shortlist.

Best fit: circle.so

Circle maps unusually well to your requirements:

• Tiered permissions: You can create access groups that control which spaces members can see. For example, Alumni → Premium Alumni → Mentor. Circle Circle
• Membership tiers: Circle supports paid memberships and subscription groups, including upgrade/downgrade paths between tiers. Circle
• Member directory: It has a searchable directory with rich member profiles, including fields such as bio, location, and social links. Circle Circle Community
• Course integration: Courses, discussions, events, and alumni networking can live in the same community rather than being stitched together. Circle
• Granular spaces: You could have spaces like: - All Alumni
• Cohort-specific groups
• Job/networking board
• Premium alumni lounge
• Mentor community
• Instructor/leadership area
• Automation: On the Business plan, workflows and custom profile fields give you more sophisticated ways to automate onboarding and access. Circle

Circle's current listed pricing is $89/month for Professional and $199/month for Business, with additional higher-end options. Circle

Another strong option: Mighty Networks

mightynetworks.com is worth considering if member networking/discovery is more important than sophisticated permission architecture.

It has rich member profiles, custom fields, badges, and ways for members to discover people with similar characteristics or locations. Mighty Networks

My recommendation

I'd choose Circle if your model looks something like:

The particularly useful part is that Circle's access groups are explicitly designed for tiered access, and you can combine groups to build cumulative permissions—for example, Pro gets everything Alumni gets plus Pro-only spaces. Circle

Bottom line: If this is an extension of an existing course business, I'd pick Circle. If the primary product is a highly social alumni network and networking/discovery is the centerpiece, I'd also evaluate Mighty Networks.

For an alumni community with membership tiers + granular access + a searchable member directory, I’d shortlist Circle and Mighty Networks, with Circle as my first choice.

1. circle.so — best overall fit

Circle maps very cleanly to an alumni model:

• Tiered memberships: You can create different membership tiers and use paywalls to control access to the whole community, individual spaces, or combinations of spaces. Circle Circle
• Granular permissions: Access groups let you define which spaces a particular group can access, and admins can see/manage an individual's access. Circle Circle
• Member directory: Circle has a searchable member directory, rich profiles, and dedicated "member spaces" that can function as specialized directories. Circle Circle
• Courses: You can keep alumni courses, discussions, events, and community in the same platform. Circle
• Custom member fields: The Business tier adds custom profile fields, which is useful for alumni data such as graduation year, cohort, location, industry, employer, expertise, etc. Circle

A structure could look like:

You could then have spaces for General Alumni, Cohorts, Jobs & Opportunities, Mentoring, Events, Resources, and Premium Content, with access controlled by tier.

2. mightynetworks.com — strong alternative

Mighty is particularly good if you want the community to feel more like a social network.

Its "Plans" system can gate the entire network or particular Spaces, and plans can require payment, approval, or screening questions. It also supports limited memberships that give someone access to specific Spaces without opening the entire network. Mighty Networks Developer Mighty Networks Developer Mighty Networks Developer

That's useful for something like:

Free Alumni → Paid Alumni+ → Mentor → Executive/Lifetime

My recommendation

Choose Circle if the alumni directory and structured permissions are central to the product. Its combination of searchable profiles, custom fields, access groups, membership tiers, courses, and events is particularly well suited to an alumni organization. Circle Circle

Choose Mighty Networks if member interaction/social networking is the primary experience and you want sophisticated "plans" to drive different community experiences.

If you tell me how many alumni you have, what the tiers are, and whether membership is free/paid, I can also lay out the exact Circle permission architecture I'd use—including tiers → spaces → directory visibility → courses → events.

For a course-alumni community with membership tiers, different access levels, and a strong member directory, I’d shortlist these:

My pick: Circle

For your use case, Circle is probably the strongest choice. It has explicit access groups that can be used to create tiered permissions, including combinations such as Basic → Plus → Pro. Each tier can unlock different spaces, courses, events, or discussions. Circle Circle

It also has member spaces, essentially configurable member directories. You can create separate directories—for example, "All Alumni," "Certified Alumni," "Mentors," or "Founders"—and control who can see/access each one. Circle

A structure I'd consider:

• Alumni — Free - General discussion
• Alumni directory
• Community events
• Alumni Plus - Everything above
• Premium workshops
• Private discussion spaces
• Advanced resources
• Alumni Pro / Mentor - Everything above
• Mentor directory
• Mentor-only discussions
• Exclusive events
• Ability to mentor newer alumni
• Staff/Admin - Full management access

Circle's current Professional plan lists a searchable member directory, rich profiles, paid memberships, courses, events, and discussions; its Business plan adds workflows and custom profile fields, which could be particularly useful for alumni data such as graduation year, cohort, location, industry, expertise, or employer. Circle Circle

When I'd choose something else

Mighty Networks is worth choosing if the network itself is the product—lots of member-to-member networking, groups, and potentially a branded mobile app. It specifically positions itself around paid/tiered communities and customizable "Spaces." Mighty Networks

Hivebrite becomes more interesting if you're building a large, formal alumni association rather than a course community. It's specifically positioned for alumni and professional networks, with networking and mentoring functionality. Mighty Networks

Skool is attractive if your priority is simply "course + discussion + engagement" and you don't need sophisticated alumni-directory architecture. It's considerably more opinionated and less flexible than Circle.

Bottom line: I'd start by evaluating Circle vs. Hivebrite. If this is a course business/community, Circle is likely the better balance of modern community UX, tiered access, courses, events, and directory functionality. If this is becoming a permanent professional alumni network with thousands of members and formal networking/mentoring programs, Hivebrite deserves a serious look.

For a course alumni community with tiered memberships, gated access, and searchable member directories, I’d shortlist platforms based on how “community-first” versus “membership-system-first” you need to be.

Strong options

My recommendation by scenario

If this is for a paid course/coaching alumni network

Choose:

1. Circle
2. Mighty Networks

Typical setup:

• Tier 1: Alumni (basic discussion + events)
• Tier 2: Pro Alumni (mentor matching + advanced resources)
• Tier 3: VIP Network (small groups, office hours, private directory)

These platforms make it easy to gate spaces by membership level.

If the directory is a core value proposition

Choose:

• Hivebrite
• Almabase
• 360Alumni

They are closer to “LinkedIn for your alumni” with structured profiles, search, and networking. Guideflow 360Alumni

If you need custom permissions and a lot of control

Consider:

• Salesforce
• WordPress + membership plugins

A WordPress membership setup can create unlimited tiers, custom roles, gated content, and member directories, but requires more administration. Paid Memberships Pro

A good alumni tier model to implement

• Free Alumni

• Profile
• Community announcements
• Public events
• Certified Alumni

• Full directory access
• Private groups
• Alumni-only resources
• Premium Alumni

• Mentorship matching
• Job board
• Expert sessions
• Private mastermind groups
• Founding/VIP Alumni

• Executive network
• Exclusive events
• Direct access to instructors

For most course businesses, I’d start with Circle or Mighty Networks unless the alumni directory itself is the product—then I’d lean Hivebrite.

For a course-alumni community with multiple membership tiers, granular access, and a member directory, I’d shortlist these:

My pick: Circle

circle.so is probably the cleanest match for your requirements.

Its Access Groups let you define exactly which spaces a member can access, and you can attach those groups to invitations, onboarding, or paid memberships. Circle Circle

For example, you could structure your alumni community as:

• Alumni — Free

• General alumni directory
• Community announcements
• Alumni discussion
• Events
• Alumni Plus

• Everything above
• Private industry groups
• Job board
• Workshops
• Exclusive events
• Alumni Pro / Fellows

• Everything above
• VIP discussion space
• Mentorship network
• Faculty/expert sessions
• Leadership opportunities

Circle also supports subscription groups, so members can upgrade/downgrade between tiers rather than maintaining multiple simultaneous subscriptions. Circle

And importantly, access can be automatically removed when a paid membership ends, which is useful if alumni benefits are tied to an active tier. Circle

Why I'd choose Circle for alumni

The important distinction is that you're not just looking for "a community platform." You're effectively building a membership system + alumni directory + gated network.

Circle gives you:

• Tier → access mapping without manually managing every member.
• Private spaces/groups for specific cohorts, industries, leadership levels, etc.
• Member profiles and audience management for your directory.
• Paid or free memberships and upgrades/downgrades.
• Ability to give an individual member an exception to the normal tier when necessary. Circle
• Events, chat, discussions, courses/content, and messaging in the same environment. Circle

Mighty Networks is the other one I'd seriously consider

mightynetworks.com is particularly attractive if the networking/social aspect is more important than sophisticated access administration. It supports private groups/cohorts, unlimited members and spaces, events, chat, and member management. Mighty Networks

I'd lean Mighty Networks if your vision is:

"We want alumni to discover each other, form groups, attend events, and build relationships."

I'd lean Circle if it's:

"We need a structured alumni membership program where different tiers unlock specific benefits and areas."

For your description, I'd start with Circle.

If you tell me your proposed tiers (e.g. Free Alumni / Paid Alumni / VIP / Faculty) and roughly how many alumni you expect, I can map out the exact Circle architecture—spaces, access groups, permissions, directory fields, and tier rules.

For a course-alumni community with tiers, gated areas, and a searchable member directory, I’d put Circle at the top of the shortlist.

Best fit: circle.so

Circle maps particularly well to your requirements:

• Tiered permissions: Its Access Groups let you define which spaces each tier can access. Circle explicitly supports structures like Free → Plus → Pro, with higher tiers inheriting access to lower-tier spaces. Circle Circle
• Paid tiers: You can create paid memberships/subscriptions and automatically grant or revoke access based on membership status. Circle
• Member directory: Searchable member directory plus rich profiles are included. Circle
• Custom alumni profiles: The higher Business plan adds custom profile fields, which is useful for things like graduation year, cohort, industry, location, employer, expertise, etc. Circle
• Courses + community: You can keep course content, alumni discussions, events, and networking in the same system rather than stitching together a course platform and a separate community. Circle
• Automations: Business includes workflows, which could automate things like “completed Course A → Alumni tier,” “5-year alumni → Legacy tier,” or onboarding based on cohort. Circle

How I'd structure it

The nice thing is that Circle's access groups let you layer permissions rather than manually manage every member's individual access. Circle

Alternative: Mighty Networks

mightynetworks.com is worth considering if networking/discovery is more important than course infrastructure. Its member experience emphasizes discovering people with similar interests, locations, goals, and backgrounds, and it supports custom profile fields and badges. Mighty Networks

I'd lean:

Circle → best overall for a course-alumni ecosystem with structured tiers and gated content.
Mighty Networks → stronger candidate if the primary product is the alumni network itself.

Circle's current Professional plan is listed at $89/month and includes unlimited members, searchable directory, profiles, paid memberships, courses, events, and discussions; Business is $199/month and adds workflows and custom profile fields. Circle

If you tell me how many alumni you have, how many tiers you want, and whether membership is paid or included with course completion, I can narrow this to 2–3 platforms and map the exact permission structure.

Yes. For a course-alumni community with tiers, gated areas, and a searchable member directory, I’d put Circle at the top of the shortlist.

My recommendation: Circle

It maps very cleanly to an alumni model:

The particularly useful feature is Access Groups. You can define exactly which spaces each tier receives. For example, Circle explicitly supports a Basic → Plus → Pro structure where each higher tier inherits the previous tier's spaces. help.circle.so

You could structure your alumni community like:

Alumni

• General discussion
• Alumni directory
• Events
• Job opportunities
• Resources

Alumni Plus

• Everything above
• Premium workshops
• Expert sessions
• Private networking groups

Alumni Pro / Lifetime

• Everything above
• VIP mastermind
• Founder/instructor access
• Exclusive events
• Private cohort groups

Circle also has a searchable member directory and rich profiles, and its newer member-space functionality can create private directories for particular membership tiers or groups. circle.so

One important distinction

If you're thinking of "permissions" as content/access permissions, Circle is excellent. You can control access at the space/group level and tie it to memberships/paywalls. Access can also be automated through workflows. help.circle.so

If you mean very granular organizational permissions—e.g. alumni chapter leaders can manage only their chapter, regional admins can see certain members, corporate sponsors get a completely different portal—I'd evaluate Circle's Business tier and potentially its API/customization capabilities. The Business plan currently includes custom profile fields, workflows, and API options. circle.so

Runner-up: Mighty Networks

Mighty Networks is the other one I'd seriously consider. It also has member profiles/directories, courses, paid memberships, spaces, events, and tiered access. www.mightynetworks.com

I'd lean Circle if your priority is structured alumni management + clean tiered permissions. I'd lean Mighty Networks if the priority is more of a social-network/mobile-app experience.

If you tell me your expected number of alumni (e.g. 500, 5,000, 50,000) and the tiers you have in mind, I can narrow this down to 2–3 platforms and show exactly how I'd architect the permissions.

Yes. For an alumni community with membership tiers, gated areas, and a searchable member directory, I’d shortlist these:

My pick: Circle

Circle maps particularly well to an alumni model because its Access Groups can assign predefined collections of spaces to different membership levels. You can also stack groups, so a higher tier can inherit everything from lower tiers. help.circle.so

For example:

• Alumni — general discussion, alumni directory, events
• Plus — everything above + advanced workshops + job board
• VIP / Mentor — everything above + mentor directory + private mastermind
• Faculty/Admin — administrative spaces and moderation

Circle also has dedicated member spaces that function as customizable directories, and those directories can themselves be gated by access level. help.circle.so

Its current Professional plan includes searchable member directory, rich member profiles, paid memberships, courses, discussions, and events; Business adds things like custom profile fields and workflows. circle.so

Mighty Networks is the strongest alternative

Mighty's Plans can control access to the entire network or specific Spaces, including limited memberships. Members can also be moved between plans, which is useful if alumni upgrade from "Alumni" → "Professional" → "VIP." faq.mightynetworks.com

I'd favor Mighty if the community experience itself—feeds, social interaction, events, networking—is more important than having a highly structured alumni portal.

If your priority is specifically "course alumni + tiers + permissions + directory," I'd start with Circle. It gives you a clean way to model the alumni organization without having to bolt a membership system onto a generic community platform.

If you tell me your 3–5 tiers and what each tier should be able to access, I can map out the exact Circle/Mighty setup and tell you which one fits better.

Yes. For a course-alumni community with membership tiers, gated content, and a searchable member directory, I’d shortlist these:

My recommendation: Circle

For your use case, Circle is probably the cleanest choice. It has a searchable member directory, rich member profiles, courses, events, discussions, and paid memberships in the same platform. circle.so

More importantly, Circle's Access Groups let you define which spaces each tier can access. You can structure something like:

• Alumni — Free: alumni directory, announcements, general discussion
• Active — $X/year: everything above + workshops, job board, private groups
• VIP — $X/year: everything above + masterminds, office hours, premium content
• Mentor: special mentor spaces + ability to interact with mentees

Access groups can be combined so higher tiers inherit lower-tier access, and admins can make individual exceptions when necessary. help.circle.so

Circle also currently lists custom profile fields on its Business plan, which could be useful for an alumni directory—for example, cohort/year, location, industry, role, company, expertise, and whether someone is available as a mentor. circle.so

Mighty Networks is the strongest alternative

Mighty is particularly attractive if you want the alumni community to feel like a social network, rather than a course platform with a community attached. Its Plans can gate the entire network or individual Spaces, and members can be moved between plans. faq.mightynetworks.com

It also has member profiles, member lists, messaging, groups/Spaces, events, and courses. www.mightynetworks.com

When I'd choose Higher Logic/Hivebrite

If this is going to become a large, formal alumni association—thousands/tens of thousands of alumni, sophisticated membership administration, organizational integrations, chapters, etc.—I'd look harder at Higher Logic or Hivebrite. Higher Logic, for example, has explicit Membership Types plus Security Groups and granular community permissions. support.higherlogic.com

Bottom line:
If you're building this today and want courses + alumni networking + tiered access + directory + events without assembling multiple systems, I'd start with Circle, with Mighty Networks as the main alternative.

If you tell me roughly how many alumni you have, how many tiers, whether tiers are paid, and whether you need a course/LMS component, I can narrow this to the best 2–3 and map out exactly how I'd structure the permissions.

Yes. For a course-alumni community with membership tiers, gated areas, and a searchable member directory, I’d put Circle at the top of the shortlist.

Best fit: Circle

Circle is particularly well suited because it combines:

• Tiered memberships: You can create different paid/free membership tiers and connect each to specific access.
• Granular permissions: Circle uses access groups and spaces, so you can decide exactly which tier gets which community areas. Access can also be automatically revoked when a paid membership ends. help.circle.socircle.so
• Member directories: Its "member spaces" function as customizable directories. You can create separate directories for different alumni groups and filter members by tags, roles, levels, and custom profile fields. help.circle.so
• Private/secret areas: You can make spaces open, private, or secret—useful for things like an executive alumni tier or invite-only mastermind. help.circle.so
• Courses + community: If you want the alumni community to remain connected to the original course, Circle also supports courses, events, live streams, payments, and newsletters. help.circle.socircle.so

A structure like this would work nicely:

The important part is that tiers don't just have different labels—they actually control access to spaces and directories.

Other platforms I'd consider

Mighty Networks — strong alternative if you want a more social/network-centric experience. It supports plans and controlling access to networks/spaces. docs.mightynetworks.com

Kajabi — worth considering if the course/business is the center of gravity and the alumni community is secondary. It has communities, circles, custom profiles, and member directories, but the community experience is generally less purpose-built for a sophisticated alumni network. www.mightynetworks.com

My recommendation: Circle if the alumni network itself is important. It gives you the cleanest model of "membership tier → access group → spaces/directories" without having to build a permissions system yourself.

If you tell me your number of alumni, number of tiers, and whether members pay annually/monthly or get access automatically after completing the course, I can map out the exact platform architecture I'd use.

For a course-alumni community with membership tiers, gated areas, and a searchable member directory, I’d shortlist these:

My pick: Circle

Circle is particularly well suited to an alumni model because you can create access groups that automatically determine which spaces someone can see. Its documentation specifically supports tiered structures such as Basic → Plus → Pro, where each higher tier inherits the previous tier's spaces and adds additional ones. help.circle.so

For example:

• Alumni — community discussions, alumni directory, events
• Member — everything above + advanced workshops
• Mentor — everything above + mentor-only discussions
• Faculty/Staff — administrative spaces

Circle also has a searchable member directory and rich member profiles on its Professional plan, while Business adds custom profile fields and APIs. circle.sohelp.circle.so

That means you could give alumni profiles fields like:

• Cohort / graduation year
• Course completed
• Location
• Industry
• Job title
• Skills
• “Open to mentoring”
• LinkedIn / website
• Current organization

…and let alumni search/filter the directory around those attributes.

Mighty Networks is the main alternative

Mighty is compelling if your vision is less “course community” and more private professional network. Its Plans can control access to the network or individual Spaces, including paid, approval-based, or screening-question access. docs.mightynetworks.com

It also has a fairly sophisticated member-management system: admins can filter members by Spaces, Plans, member type, tags and badges, and member profiles can contain custom fields, location, bio, etc. docs.mightynetworks.com

One particularly useful distinction: Mighty supports limited memberships, where someone can access particular Spaces without getting access to the whole network. docs.mightynetworks.com

What I'd choose

Choose Circle if: your alumni community is an extension of your courses and you want clean, granular content/community permissions.

Choose Mighty Networks if: the alumni network itself is the primary product—networking, profiles, groups, events, and member interaction.

For your specific description, I'd start with Circle. Its access-group model maps very cleanly onto alumni tiers, and the searchable directory is already part of the platform. circle.sohelp.circle.so

If you tell me how many tiers you envision and what each tier should be able to access, I can map out the exact Circle/Mighty structure and point out which platform handles your permission model better.

For a course-alumni community with multiple membership tiers, differentiated permissions, and a searchable member directory, I’d shortlist Circle and Mighty Networks, with Circle as my first choice.

1. Circle — probably the best fit

Circle has Access Groups, which let you define exactly which spaces each tier can access. You can layer groups so, for example:

• Alumni → general discussion + alumni directory
• Plus → Alumni + monthly events + career resources
• VIP → everything above + mastermind + private coaching space

Circle explicitly supports this kind of tiered structure, including free/invite access and paid tiers. help.circle.so

Its member directory is also particularly relevant: profiles can be searchable/filterable, with things like location, tags, and activity information. www.mightynetworks.com

Why I'd lean Circle: it's very good when you want the community to feel like a professional alumni network, rather than primarily a social network.

Circle

2. Mighty Networks — strong alternative

Mighty uses Plans to control access to the network and individual Spaces. Plans can incorporate payment, approval, or screening questions, and members can be moved between plans. docs.mightynetworks.com

It also supports member profiles, directories, search, tags and badges, and has particularly strong built-in course/event/community functionality. www.mightynetworks.com

I'd choose Mighty if your alumni community is going to be closely connected to courses, events, challenges, livestreams, and a more social/mobile experience.

Mighty Networks

What I'd build

For an alumni program, I'd probably structure it as:

Tier 1 — Alumni

• Member directory
• Alumni discussion
• Job/opportunity board
• Events
• Resource library

Tier 2 — Active

• Everything in Alumni
• Small-group discussions
• Exclusive workshops
• Advanced resources

Tier 3 — Leadership/VIP

• Everything above
• Private mastermind
• Mentor/coach access
• Leadership-only events
• Exclusive directory designation

Then use tags/custom profile fields for things like graduation year, course/cohort, industry, location, expertise, and whether someone is available as a mentor.

Bottom line: If the primary product is “a professional community for people who completed our courses,” choose Circle. If it's “our courses + a vibrant social community + events,” choose Mighty Networks.

For a course-alumni community with tiered permissions + a searchable member directory, I’d shortlist these:

My pick: Circle

Circle is particularly well suited to your use case. Its Access Groups let you define which spaces each tier can access, and those groups can be attached to invitations or paid memberships. For example: help.circle.so

• Alumni → general discussion, alumni directory, events
• Premium → Alumni + private mastermind spaces
• Mentor/Leader → Alumni + mentor rooms + leadership resources
• Faculty → special faculty/admin spaces

It also has a searchable member directory and rich member profiles, and its current Professional plan includes courses, events, discussions, paid memberships, and the directory. circle.so

One particularly useful feature is that membership tiers can gate either the entire community or specific spaces, so you don't have to create separate communities for each cohort or level. circle.so

Mighty Networks is worth considering

Mighty is arguably the closest alternative. Its Plans can control access to the entire network or particular Spaces, and you can have full versus limited members. It also lets you filter/manage members by plan, space, member type, tags, and badges. faq.mightynetworks.com

I'd choose Mighty over Circle if the experience you want is more of a social network/community with courses and events built into it.

What I'd build for an alumni community

I'd probably structure Circle like this:

Community

• Alumni Directory
• General Discussion
• Events
• Jobs & Opportunities
• Announcements

Tier 1 — Alumni

• Everything in Community

Tier 2 — Professional

• Everything in Alumni
• Professional Development
• Small-group discussions
• Exclusive events

Tier 3 — VIP / Mastermind

• Everything above
• Private mastermind groups
• Mentoring
• Leadership resources

Then use profile fields for things like graduation year, course/cohort, industry, location, expertise, and "open to mentoring." Circle's Business tier adds custom profile fields and workflows, which could be useful if the directory needs to become sophisticated. circle.so

Bottom line: I'd start with Circle unless your primary requirement is sophisticated course delivery rather than community. For "our graduates should be able to find each other, interact, and have different levels of access" Circle is probably the cleanest fit.

For a course alumni community with multiple tiers, different access levels, and a searchable member directory, I’d shortlist these:

My pick: Circle

Circle maps particularly well to an alumni model because you can create membership tiers/paywalls and assign each tier access to particular spaces. Its subscription groups can represent tiers that members can upgrade/downgrade between. help.circle.so

For example:

• Alumni — general community + alumni directory
• Pro Alumni — everything above + advanced workshops + expert groups
• VIP / Fellows — everything above + mastermind + private events
• Faculty/Mentor — special moderation/access permissions

You can also create private or secret member-directory spaces, and directories can be filtered by things like role, tags, level, and custom profile fields. help.circle.so

Circle also supports assigning moderator permissions to particular spaces, which is useful if some alumni become mentors or community leaders. help.circle.sohelp.circle.so

Mighty Networks is the strongest alternative

Mighty's Plans are specifically designed for controlling access to the network and individual spaces. A plan can give someone full network membership or limited access to selected spaces, making it quite flexible for alumni tiers. faq.mightynetworks.com

I'd choose Mighty if the community/networking aspect is more important than having a polished course + membership architecture.

What I'd build

If you're starting from scratch, I'd lean Circle and structure it roughly like:

Community

• Announcements
• Alumni Lounge
• Member Directory
• Jobs / Opportunities
• Events

Tier 1 — Alumni

• Lounge
• Directory
• Events

Tier 2 — Active Alumni

• Everything in Tier 1
• Advanced content
• Cohort-specific groups
• Workshops

Tier 3 — Alumni Plus

• Everything above
• Mastermind
• Private events
• Mentor matching

Roles

• Member
• Mentor
• Moderator
• Admin

The important distinction is to use tiers for what someone is entitled to access, and roles for what someone is allowed to do. Circle's access groups/paywalls make that separation fairly clean. help.circle.sohelp.circle.so

If you tell me how many alumni you expect (e.g. 500 vs. 10,000), whether the tiers are paid, and whether you already use a course platform, I can narrow this down to the best 2–3 options and compare their current pricing/features.

For a course alumni community, you’ll want a platform that supports:

• Tiered membership levels (e.g., Alumni Free, Alumni Plus, VIP/Mentor)
• Permission-based access to groups, content, events, and courses
• Member directory/profiles with searchable fields
• Private spaces for cohorts, regions, interest groups, or premium tiers
• Admin/moderator roles
• Ideally: integrations with your LMS, email system, and payments

Here are the strongest options:

My recommendation by scenario

1. You want a vibrant alumni network where people connect
→ Mighty Networks

• Tier examples:
  • Alumni (free): directory + general discussions
  • Alumni Plus: private workshops + advanced resources
  • Fellows/Mentors: leadership spaces + mentoring tools
• You can gate access to different Spaces using plans and membership levels. docs.mightynetworks.com

2. You want a professional association feel
→ Circle

• Structure:
  • “All Alumni”
  • “Class of 2026”
  • “Career Growth”
  • “VIP Executive Circle”
  • “Mentor Lounge”
• Members can have profiles and appear in directories with filters. www.mightynetworks.com

3. Your alumni community is mainly a retention layer after selling courses
→ Kajabi

• Good if you already sell courses through Kajabi and want alumni access connected to purchases/offers. help.kajabi.com

A common alumni setup

Tier 1 — Alumni

• Member directory
• Community feed
• Monthly events
• Networking groups

Tier 2 — Pro Alumni

• Exclusive courses
• Office hours
• Private discussion areas
• Job board

Tier 3 — Fellows/Mentors

• Mentor directory badge
• Leadership forums
• Ability to host events

For most course alumni communities, I would shortlist Mighty Networks vs Circle first. Mighty is stronger when the goal is relationship-building and member discovery; Circle is stronger when you want a polished professional community structure. www.mightynetworks.com

A few details would narrow this down:

1. How many alumni do you expect (100, 1,000, 10,000+)?
2. Is the community paid, free, or mixed tiers?
3. Do you already use an LMS (Kajabi, Teachable, Thinkific, Moodle, etc.)?

For an alumni community with tiered membership, granular access, and a searchable member directory, I’d put Circle at the top of the shortlist.

Best fit: Circle

Circle maps unusually well to your requirements:

• Tiered access: its Access Groups let you define which spaces each tier can access. You can stack groups so, for example, Gold gets everything Silver gets plus additional spaces. help.circle.so
• Different permission levels: separate community access from admin/moderator privileges, so being a Gold member doesn't automatically make someone an admin. help.circle.so
• Member directory: Circle has a dedicated directory plus customizable member spaces, where members can filter profiles by things like role, tags, level, and custom profile fields. help.circle.so
• Private/secret areas: useful for alumni cohorts, mentor groups, VIP rooms, regional groups, etc. help.circle.so
• Paid tiers: access groups can be attached to paywalls, so access can automatically correspond to a paid membership. help.circle.so
• Good alumni use case: you could structure it as Alumni → Member → Plus → VIP, while also having separate spaces for each graduating cohort, industry, geography, or mentoring program.

A possible structure

I'd use access groups for the tiers and tags/custom profile fields for attributes such as graduation year, industry, location, and expertise. That keeps "what can you access?" separate from "who are you?"—which becomes important as the community grows.

Mighty Networks is another strong candidate, particularly if you want the alumni community to be heavily centered around courses, events, and member engagement; it has community, courses, payments, and member automation in the same ecosystem. www.mightynetworks.com

My recommendation: choose Circle if granular permissions + a sophisticated alumni directory are the priority. Choose Mighty Networks if the community is more of a combined courses + community + events product.

If you tell me roughly how many alumni you have and how many tiers you envision, I can narrow this to 2–3 platforms and compare their pricing, permissions, directory, SSO, and course integrations.

For a course-alumni community, Circle is probably the strongest fit.

Circle supports both the pieces you’re asking for:

• Tiered access: You can create membership tiers/paywalls and use access groups to automatically grant each tier access to specific spaces. For example, Alumni → Plus → VIP, with each tier inheriting additional spaces. help.circle.so
• Member directory: Circle has a searchable member directory with rich profiles. You can also create separate member directories for particular groups or tiers and filter members by fields, tags, roles, level, etc. circle.sohelp.circle.so
• Alumni profiles: Members can have profiles with things like location, role, interests, bio, and custom fields—useful for an alumni network rather than just a discussion forum. circle.sohelp.circle.so
• Courses + community: It includes courses, discussions, events, live rooms/streams, messaging, and the community layer in the same platform. circle.so
• Automation: The Business plan adds workflows and custom profile fields, which becomes useful when you want things like “completed Course X → automatically give Alumni access.” circle.so

How I'd structure your alumni community

The nice thing is that access groups can overlap, so you don't have to create a completely separate community for each tier. help.circle.so

Pricing-wise: Circle currently lists Professional at $89/month and Business at $199/month. Professional already includes unlimited members, courses, events, searchable directory, rich profiles, and paid memberships; Business adds workflows and custom profile fields. circle.so

My recommendation: Start with Circle Professional if your requirements are mostly tiers + directory + community. Move to Business if you need automated alumni segmentation, custom directory fields, or more sophisticated workflows.

If you tell me how many alumni you expect and what the 2–4 tiers are, I can also compare Circle vs Mighty Networks vs Bettermode specifically for your use case and recommend the cheapest/best architecture.

For a course-alumni community, Circle would be my first choice.

It maps particularly well to your requirements:

Circle's access groups are specifically designed for tiered permissions. For example, you could have Alumni → Plus → Executive tiers, with each tier automatically receiving access to additional spaces. help.circle.so

Its Professional plan currently includes unlimited members, courses, events, paid memberships, a searchable member directory, and rich member profiles; Business adds workflows and custom profile fields. Current listed pricing is $89/month Professional and $199/month Business. circle.so

How I'd structure your alumni community

• All Alumni — directory, announcements, general discussion, events
• Active Alumni — industry groups, mentoring, job board
• Premium/Executive — exclusive events, advanced resources, private groups
• Faculty/Staff — administrative/moderator permissions

I'd use access groups for the membership tiers and spaces for the actual content/community areas. That keeps permissions manageable as the alumni population grows.

One alternative worth considering

Mighty Networks is also strong if the community/networking experience is more important than course administration. It has member-focused features, courses, payments, and automations, including the ability to invite highly engaged members into advanced spaces. www.mightynetworks.com

Bottom line: If your priority is “course alumni + structured tiers + controlled access + searchable directory,” I'd choose Circle. circle.so
