Key facts
- Announced Oct 13, 2026 at Workday Rising; price not disclosed; expected to close in Q4 of Workday’s fiscal 2027, subject to customary conditions (Workday release, as summarized by press)
- C1.ai: ‘the identity platform for the AI era’; manages access for people and agents, requires human approval for certain actions and logs every action (Orrick, Workday’s adviser)
- Workday: ‘Workday will become the identity governance layer for people, money and agents’; C1 extends the Workday Agent System of Record with controls over what registered agents can access in Workday and other systems
- Funding: C1.ai had raised $111M (Techmeme summary of the Portland Business Journal)
What happened
Workday framed the deal as making HR the control point for AI agents: every hire, role change and exit is already a Workday event, and the same events would grant or revoke agents’ access. Coverage noted the announcement says nothing about C1 customers that do not use Workday for HR. The expected-close detail comes from search summaries of the Workday release; the PDF was not opened.
Why it matters
After a run of incidents in which agents reached systems they should not have (see the OpenAI misalignment reports and India’s CERT-In warning), identity and access control for agents has become a product category that large enterprise vendors now buy into.
