British startup exits stealth with $20 million in seed-stage financing led by US investors Scout Ventures and Artis Ventures.

Valarian, a British startup selling an isolation-first infrastructure platform to defense and public-sector customers, has exited stealth with a fresh $7 million strategic round led by US investors Scout Ventures and Artis Ventures.

The company said the new capital lifts its total seed raise to $20 million. Angel investor Gokul Rajaram also joined the round, alongside earlier backers Molten Ventures, IQ Capital and MD One.

Valarian said its flagship platform, called ACRA, segments data and communications into tightly controlled “compartments,” a design the founders say they honed in military and high-finance environments where trust routinely breaks down. 

After piloting ACRA in regulated enterprises, the company is spinning up Valarian Defence, a deployment track aimed at government agencies and national-security programs that need hardened communications and coordination tools.

The company said the funding will be used on government partnerships and product work to slot ACRA into classified and mission-critical networks.

While the market for “control-first” security platforms is crowded with zero-trust vendors, Valarian and its investors are betting that enforced isolation instead of policy-driven segmentation will resonate with defenders handling highly sensitive data.

To date, the company has developed two core product lines: Privileged Communication and External Comms Capture for regulated enterprises, while a Valarian Defence offering extends these capabilities to deployments requiring enforced compartmentalization and secure coordination infrastructure.
