A workspace is your agency. Everything else — people, client spaces, files, approvals — lives inside it, and most agencies never need a second one.
To create one, go to onbrief.online, choose Start a workspace, and give it your agency's name. That name is what your clients see at the top of every space you share with them, so use the name they know you by rather than the one on your registration documents.
The person who creates the workspace becomes its first owner. Owners can change billing, add and remove people, and close the workspace. You can appoint more owners later, and you should: a workspace with one owner is a workspace that stops when that person is on holiday.
Your workspace starts on a fourteen-day trial with no card and no seat limit, so the whole team can come in and try it before anyone decides anything.
