Hub Steward is an agency builder. An agency is any member organisation: a farmers' group, a school, a utility, a bank. Each one has actors, roles, objectives, workflows and risks, and some of its roles can be served by AI agents. A manager designs the agency in the console: goals, objectives and workflows, created and enhanced with AI; roles held by people or AI agents; permissions set on each workflow step; and risks as bowties, with a top event, threats, consequences and controls. A review reads the whole agency and surfaces the gaps, each fix lands in a new draft version, and publishing makes it live, with every earlier version kept. Members use the phone app, Do Something!, which is driven by the workflows: they see the steps waiting on them, fill the forms, and chat in groups where the AI agents take part. The problem it solves: groups that run on a few managers and a lot of coordination. The demo follows the Siaya Farmers' Group in Kenya: farmers opening a group order for fertiliser, suppliers filling one order, coordinators and officers keeping it in order, with a Farmers' agent and a Suppliers' agent doing part of the work. The demo holds eight such agencies, from a community computer lab to a clinical research organisation, all synthetic.
