Expert Communities
An expert community is a group of experts you can reach through a shared directory or membership, usually without a team recruiting, screening and scheduling for you. Some are searchable directories of academics or professionals, others are invite-only groups or platforms for freelance experts.
Here you’ll find the communities and expert directories in our directory. It’s a smaller and more varied group than the other hubs, so check each profile for how that specific company works. Which one suits you depends mainly on whether you want to contact experts yourself or have them arranged for you.

How do you choose an expert community?
How do experts join, and who checks them? Some communities are open to anyone who lists a profile, others are invite-only. Ask what is verified, such as credentials, employer or affiliation, and what is left for you to confirm.
Who handles compliance? An expert network usually screens experts and briefs both sides before a call. In a directory or community, that is more often your job, so check what the platform does and doesn’t cover before you reach out.
What can you do there, and what does it cost? Some let you contact experts directly, while others use a platform to arrange it. Some are free to search, and others charge for access or per project. Check what is included.
