Which software can you recommend for mastermind groups?

I have a mastermind group of five people and we are looking for a software/service/self-hosted application where we can organize our group + meetings. Nice to have would be member permissions, a group chat, file storage and collaboration tools in general. Thanks for any advice.

    Look into notion.so as well. May not have the features you need but it's a wide open, customizable workspace.

You can create conferences, share files, create projects and assign tasks to your teammates. You can also share knowledge using intranet forum. Voice and video calls, screen sharing, and remote control are provided too.
