Workspaces
Context set once, used by every project and every agent under it. Client separation by structure, not by discipline.
Set once
Brand guidelines, strategy documents, reference material and files live at workspace level and flow into every project as background context. New project, same starting position: the agent already knows the client.
Separation
Run a dozen clients through one general assistant and nothing keeps one client's context out of another's session. In Multiply the workspace is the boundary: each client's material stays scoped to its own workspace.
Short answers first. The longer ones are a walkthrough away.
Anything that is true of the client rather than of one project: brand guidelines, strategy documents, reference material, files. Projects underneath inherit it automatically.
Folders organise files for people. A workspace grounds agents: what lives there steers every task run under that client, without anyone pasting it into a prompt.
Bring one client and we will show you the before and after.
