# Workday buys agent-identity startup C1.ai

Full title: Workday agrees to buy C1.ai (formerly ConductorOne) to govern what AI agents and employees can access

At its Workday Rising conference on Oct 13, 2026 Workday signed a definitive agreement to acquire C1.ai, the identity-governance startup formerly called ConductorOne (about $111M raised), which controls which enterprise systems people and AI agents can reach, requires human sign-off for some actions and logs every action. Workday plans to tie agents' access grants and removals to HR lifecycle events through its Agent System of Record. The price was not disclosed.

## 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.
