Millennium rolls out AI ‘digital twins’ to 7,000 employees

Millennium Management, the $97 billion hedge fund, has made personalized AI “digital twins” available to more than 7,000 employees, including investment professionals. The technology was first piloted with roughly 1,600 assistants and is now offered across the wider workforce.

The initial test was led by Chief Information Officer Vlad Torgovnik and expanded to more than 150 users; the firm reports that 97% of pilot participants interacted with their twin each day. Each digital twin is built as a separate digital account with its own identity, email address, permissions and an audit trail.

Employees choose which applications and data their twin may access. Separate technical environments and access controls are used to restrict each assistant to its designated user’s information. The assistants are configured to perform tasks such as conducting research, preparing for meetings and managing inboxes, and they are not permitted to make decisions on behalf of staff.

Users communicate with their twins through email and other approved channels. The system can be granted access to specified internal tools and datasets to complete routine work. New hires receive a digital twin at onboarding so the assistant can be used for administrative duties from the start. Millennium records usage and permissions so each assistant’s activity is auditable.

Diana Meditz, the firm’s AI product manager, described her twin as “reviewing AI-related news overnight and scanning my inbox for relevant internal updates before the start of the working day.” Millennium said the tools are intended to reduce repetitive tasks and let employees concentrate on higher-value work.

The firm is also developing “AI teammates,” systems designed to support entire teams rather than individual users. Like the personal assistants, those team systems will have distinct identities and operate within predefined boundaries and controls. Permissions, separate environments and audit trails are cited as the primary controls to manage access and oversight as the technology is rolled out.
