Valarian has raised $50 million in Series A funding led by New Enterprise Associates, bringing the London-based company’s total raised to $70 million. The round is NEA’s first defence and dual-use investment in Europe. Lightbank, XTX Markets, Sequel and LitVC participated, along with angel investors Gokul Rajaram and Nikesh Arora.

The product is a control layer. Valarian enforces workload-level governance across the environments where critical applications, AI systems and operational workloads run — dictating how those systems communicate, access data and operate. The governance lives at the infrastructure layer rather than in each application, and every deployed capability inherits it automatically.
