For Agencies

Oneclient,oneworkspace.Theysigneverysend.

Open a workspace for each client. Upload their brand guide. Invite them as Guest with Review and approve. Agents cite that workspace's Knowledge Center — last week's other client never leaks in.

Northstar client workspace. Agent Inbox showing drafts waiting on the client's Guest reviewer. Switch organisation from Settings to open another client.

The status quo

More output, tighter retainers, and a client who will ask how.

44%say clients want faster turnaround

The retainer didn't grow. The queue did.

Nearly half of agencies say clients expect faster turnaround than a year ago. Volume moved. Review capacity didn't.

58%increased human review of AI work

They didn't buy a black box.

Most agencies raised oversight as they adopted AI. Speed without a named reviewer is how an account walks.

52%hear “how is AI used in our campaigns?”

They will ask. The inbox is the answer.

Over half of agencies get the question regularly. A Guest reviewer and an audit trail is a better reply than a slide.

55%asked to connect marketing to revenue

The report is the relationship.

The number-one client question in 2026. Attribution proposals wait in the inbox like everything else — nothing reallocates until someone signs.

Friday client sign-off

Approved drafts wait in the Agent Inbox under Needs approval. The client — a Guest — signs. Every action lands in the audit trail for that workspace.

Show what ran

Growth Analyst sends the Monday report. Performance Marketer proposes a spend shift; it waits for a named approver in this client's workspace, not a shared spreadsheet.

Your roster

The specialists a retainer actually needs.

Hire by describing the role, department and seniority. Give each one Supervised, Semi-autonomous or Autonomous; the workspace-wide Content Controls ceiling caps all of them. Team includes 5 installed agents and custom roles — enough to invite a client as Guest.

Why Ellum

Grounded. Auditable. One workspace.

This client's guide. Not last week's.

Each workspace has its own Knowledge Center. Every AI output cites an artifact from that workspace, so a line in a draft traces back to the document it came from. Delete the artifact and agents in this workspace stop citing it immediately.

Knowledge Center · per workspace

The client signs. You don't impersonate them.

Invite them as Guest with Review and approve. A freelancer gets View plus Create or edit, and nothing else. Custom roles and per-member overrides cover the rest. Every action lands in the audit trail.

Guest · Review and approve content

Switch organisation. Don't share a calendar.

Settings › Account › Switch organisation. Composer, Calendar, Inbox and the roster stay inside the workspace you opened. Nothing from Northstar schedules in Helix.

Switch organisation · one inbox per client

Early design partner

“We stopped pasting brand guides into a chatbot. Each client is a workspace. They approve in the inbox, and Friday no longer means a zip file.”

Roles you hand a client

GuestMemberCustom

A client reviewer needs View plus Review and approve. A freelancer needs View plus Create or edit, and nothing else. Custom roles are a Team plan limit.

Governance

Controls you can put in the MSA.

01One organisation per client
Switch organisation from Settings › Account. Knowledge, calendar, inbox and audit trail stay inside the workspace you opened. There is always at least one Owner.
02Guest as reviewer
Owner, Admin, Member and Guest are built in. Per-member overrides handle a Guest who also needs to connect one social account. The Owner cannot be overridden.
03Content Controls ceiling
Draft only, Review required or Full auto — a workspace-wide cap. New workspaces default to Review required, so a send does not go out because a model felt confident.
04Their knowledge stays in their workspace
Encrypted at rest and never used to train shared models. Delete an artifact and every agent in that workspace stops citing it. Public share links exist for someone outside the workspace.

Questions
