Hosted, and walled off from everything else
Your agents run on infrastructure that is ours to operate and yours to control, with one team’s material never turning up in another team’s answers.
A space per team
Each team, brand or engagement gets its own space, with its own people, its own material and its own budget. Nothing crosses between them, and nothing ever crosses between customers.
Build once, use everywhere
Set something up centrally and every team below inherits it, read-only. You are not rebuilding the same agent five times and watching the five copies drift apart.
Access that follows the shape
Give someone a role once and it applies everywhere it should, resolved in your favour. A team lead stays inside their team; an owner reaches everything without hunting for permissions.
Explore the platform
All of this, from the first agent you launch.
You do not switch it on later or grow into it. It is how the platform works from the day you start.
