One AI workspace for a workforce of thousands

Employees had two options: pay per-user licences for consumer AI tools with no governance, no integration with internal systems, and no way to share knowledge at scale, or go without entirely. Leadership wanted AI deployed across the organisation, but not in a way that created new compliance risk or fragmented adoption into a dozen disconnected tools. The requirement was clear: one governed workspace, accessible to the whole workforce, with a cost model that scaled with usage rather than headcount.

DareData deployed SierraGIA, the Sonae Sierra general assistant, as the foundation for the organisation's AI capability.\n\nThrough SierraGIA, employees access agents configured for their specific functions, with answers grounded in the organisation’s own knowledge - operational procedures, legal documentation, HR policies, commercial guidelines - and every response citing its exact source. Access is managed via the organisation’s existing Entra ID groups and single sign-on, so governance and permissions are inherited directly from the identity infrastructure already in place.\n\nOn top of this foundation, specialist agents have been built and continue to expand. SOMA, the Sierra Operations and Management Agent, supports procedures that govern the company’s shopping centres. A Legal agent answers questions grounded in contracts and policy documentation. An MS Office 365 agent helps employees manage calendars and prioritise their inbox.\n\nUnderneath every agent is the GenOS Platform. Usage is visible across teams and functions: which agents are being used, which knowledge sources drive the most queries, and where coverage is missing. As Sonae Sierra adds new agents and new knowledge sources, the same governance model and controls apply.
