## An agreement, with closing still ahead

Workday announced on October 13 that it has signed a definitive agreement to acquire C1.ai, an identity platform for employees and artificial-intelligence agents. The company presented the deal at Workday Rising in Las Vegas as a way to connect workforce changes with permissions across the software systems businesses use.

The transaction is expected to close in the fourth quarter of Workday’s fiscal 2027, which ends January 31, 2027, subject to customary closing conditions, according to Unite.AI’s coverage. That timetable describes a proposed completion window. Signing an agreement is a different milestone from completing the purchase and making the combined capabilities available.

## Access that changes with a role

Workday says C1.ai connects to systems including email, customer-relationship software, code repositories, financial applications and cloud infrastructure. Its stated purpose is to grant appropriate access when needed and remove it when it is no longer justified. Workday argues that new hires, job changes and departures are already events recorded in its platform.

Unite.AI reports the company’s description of a common problem: employees request permissions through tickets and can retain them after changing roles. The proposed combination is intended to link those permissions to the employee lifecycle. Workday says it would reduce waiting and manual approvals; those are anticipated benefits rather than independently measured outcomes of a completed integration.

## Controls beyond an agent registry

Workday’s announcement distinguishes agents operating for employees from autonomous agents with broader access. It says its existing Agent System of Record provides a central place to register and manage agents. C1.ai would extend that system to govern what agents can reach across Workday and other enterprise applications, including revoking access when a task or role ends.

Unite.AI describes the planned shift as moving beyond visibility into registered agents toward control over their permissions. That distinction is central to the acquisition’s stated rationale: knowing an agent exists does not by itself determine which information it can access. The report attributes the proposed capabilities to Workday, leaving actual performance dependent on execution after the transaction.
