Run every client's BD desk, from one workspace.

Your hub gets one shareable team link. Every counselor who follows it claims their own seat; the link is capped, expires, and can be revoked and reminted the moment it leaks, without disturbing anyone who already joined.

Clients are assigned to counselors. A counselor sees exactly their caseload; the program admin sees everything. That boundary is enforced in the product, not by convention, and it holds on every surface: projects, ledgers, audits, uploads.

Reusable join codes bring clients in at mass‑email scale: publish one code to a cohort and everyone who signs up with it lands in your workspace, already routed to the right counselor. Claiming is race‑safe, so a hundred signups in one afternoon never oversubscribe a code.

Sponsorship is the model, not a discount: everything a counselor runs for a client is covered by the hub's pool, free to that client. The payer is fixed when work starts, so nobody discovers a charge later, and a client's first question is about their bid, never about a bill.
