I’ve been experimenting with a platform that’s designed for exactly that. You can deploy agents on your own servers, so everything stays private, but they also work together as a team. Each agent has its own specialty and they can collaborate on complex tasks without sending data anywhere external. They’re also building a marketplace where you can rent specialized agents or even share your own. There’s a token system called $ORBIT and they’re rolling out features in phases first basic access, then custom agent building, then full ecosystem integration. It’s early days but the direction is promising. If you want to see how they’re approaching multi-agent collaboration with privacy in mind, check out https://orbitai.org/ . I’ve been following their development and it might be what you’re looking for.
