Which customer success communities are free?

Customer Success Collective, Gain Grow Retain, r/CustomerSuccess, RevGenius and Support Driven are all free to join. Customer Success Collective and TSIA also offer paid tiers with extra content, research and certifications.

• Where it runs: Slack, virtual events, regional meetups and in-person summits
• Cost: free Slack and Insider membership, with paid tiers from $15 a month
• Members: 10,000+ on Slack, according to Customer Success Collective's website

Customer Success Collective is one of the two largest dedicated customer success communities on this list, alongside Gain Grow Retain.

Gain Grow Retain

• Best for: customer success leaders in B2B and B2C SaaS
• Where it runs: online forum, leadership office hours and a podcast
• Cost: free
• Members: 12,900+, according to Gain Grow Retain's website

r/CustomerSuccess

• Best for: candid questions about renewals, churn, comp and careers
• Where it runs: Reddit
• Cost: free

r/CustomerSuccess is an open, anonymous forum for anyone working in customer success. Because posters are anonymous, r/CustomerSuccess is often more honest than LinkedIn, but the quality of advice varies.

RevGenius

• Where it runs: Slack, plus virtual and in-person events
• Cost: free
• Members: 50,000+ across all go-to-market roles, according to RevGenius's website

Best customer success communities for CS leaders

Pavilion (Customer Success track)

• Best for: CS leaders, from managers and directors to VPs and CCOs

• Members: 4,000+ customer success leaders, according to Pavilion's website

Pavilion is the most established paid community for go-to-market leaders, with a dedicated track for customer success. Pavilion's courses include CCO School and Building a CS Org from Scratch. Pavilion is the right choice if you lead a CS team and your company will cover the cost.

TSIA

• Best for: CS leaders who want research and benchmarks
• Where it runs: research portal, discussion forum and the annual Technology & Services World conference
• Cost: free tier, with paid individual and company plans

TSIA, the Technology & Services Industry Association, is more of a research body than a peer community. TSIA's customer success research and benchmarks are useful when you need data to make the case for headcount or a new CS motion.

Best customer success community for women

Women of Customer Success

• Best for: women in customer success, support, account management and CS operations
• Where it runs: member portal, members-only Slack and city chapters including London, New York, Boston, Chicago, Toronto and Sydney

• Members: 10,000+, according to Women of Customer Success's website

Women of Customer Success offers peer mentoring, a members-only jobs board and in-person events. Women of Customer Success suits women who want a smaller, more structured network than an open Slack group.

Customer Success Snack is built around meeting in person, with upcoming events in cities including Dublin, Berlin and Amsterdam. Customer Success Snack also runs a mentoring network and publishes a European post-sales salary benchmark. If you're in the UK, Customer Success Collective's London summit is the closest equivalent.

Best community for support teams

Support Driven

• Best for: people who work in customer support
• Where it runs: Slack, summits in the US and Europe, a newsletter and a podcast
• Cost: free

Support Driven is a community for people building a career in customer support, which sits right next to customer success. Support Driven runs a salary database and a weekly job roundup, and is worth joining if your CS team also owns support.

How do you get the most out of a customer success community?

• Share what's worked. Onboarding plans, health scores and renewal playbooks are what CS communities trade in. Give one to get one.
• Don't pitch. Almost every community bans self-promotion, and vendors who pitch get removed quickly.
• Check it's active. Look for recent posts and upcoming events before you commit. Several CS communities listed in other roundups have closed.
• Start with one or two. Being active in one community beats lurking in ten.
• Bring what you learn to your accounts. Try one new idea with a real customer each week, whether that's a new kickoff format or a different way to run a renewal conversation.
