UK-based sovereign infrastructure company Valarian announced on Tuesday that it has raised $50 million in Series A funding.

The company, which previously raised $20 million in seed capital, said the latest funding comes from New Enterprise Associates (NEA), Lightbank, XTX Markets, Sequel, LitVC, and angel investors Gokul Rajaram and Nikesh Arora.

The new investment will fund Valarian’s expansion and enable it to enhance its platform.

Valarian has developed a control layer called ACRA, which sits atop Kubernetes to govern AI models, agents, and other workloads running within an organization’s environment.

Each workload is placed in its own enclave with a dedicated policy stack covering workload identity, user identity, default-deny network segmentation, policy enforcement, short-lived secrets, scoped messaging permissions, and audit logging.
