Rilian, a McLean, Virginia-based startup specializing in agentic AI for national security, has secured $17.5 million in funding to advance its mission of integrating AI into defense systems. The company’s flagship product, the Caspian platform, acts as a command layer above existing security infrastructures, enabling the deployment of pre-trained AI agents in highly restricted environments such as air-gapped networks and compliance-sensitive systems.
The funding round underscores growing interest in AI-driven defense solutions, particularly those that prioritize sovereignty and security. Rilian’s platform is designed to operate in environments where traditional AI deployment is hindered by strict data isolation and regulatory requirements. By leveraging pre-trained agents, the company aims to offer scalable, secure AI capabilities without compromising on compliance or operational integrity.
One of Rilian’s co-founders, Nick Pompeo, brings significant industry credibility to the venture, being the son of former U.S. Secretary of State Mike Pompeo. This connection highlights the increasing intersection of AI innovation and national security policy. The startup’s approach to agentic AI—where autonomous agents perform tasks with minimal human intervention—positions it at the forefront of a new wave of defense technology that emphasizes both autonomy and control.
As governments and militaries worldwide seek to modernize their defense strategies, Rilian’s model offers a compelling pathway for integrating AI without compromising sensitive operations. The company’s focus on sovereign AI solutions aligns with broader global trends toward data sovereignty and secure, localized AI systems. With this new funding, Rilian is poised to expand its presence in the defense sector and further refine its platform for mission-critical applications.
