I've created a 'privacy engineering community' for Privado. It's an upcoming role and there's not a lot of processes / info around it. They also happen to be ICP.
So far we've had - 5 live panels picking panelists from the community, 1 in person meet, and many folks getting jobs/interviews out of it
Benefits for us so far -
1. ICP leaders (also the financial buyers) in one place
2. Easy to get speakers for dinners, events, warm introductions and panels
3. Can eventually turn to a customer because no one else is solving their problems but us
