Building a thriving community takes a lot of inspiration and creativity. But sometimes it’s hard to find new ideas and new ways of thinking through your community structure. This is true whether you’re considering adding badges or launching a community member contest. We often just need an outsider’s perspective to ensure we’re on the right track.

If you’re looking for success stories of other communities who have grown massively and engage their members in creative ways, look no further. We have put all of our case studies in one place so you can browse them for inspiration any time.

When doing our own research for this list, we noticed that no other lists of successful online communities or case studies had been updated in the last five years. Five years is basically a millennia in Internet time. So we updated the success stories and wrote one fast takeaway from each.

This is a busy community builder’s big reference list.
