Its platform, LumbraOS, includes three main products:

• Nebula: Runs AI agents and tracks their activities.
• StarChart: Builds a knowledge graph that records information and insights generated through agent workflows.
• Astrolabe: Continuously tests AI agents to check their reliability.

The platform works with models from across the large language model ecosystem. It helps organisations manage what their AI agents do, understand how they reach conclusions and maintain control over sensitive data.

Lumbra aims to make it easier for businesses to use networks of AI agents while maintaining audit trails, security controls and reliable outputs.

Why the Funding Matters

Lumbra will use the funding to expand its operations and strengthen its teams across engineering, product development, go-to-market and deployment.

The company also plans to bring its platform into regulated commercial sectors, building on its experience working with national-security customers.

Who founded Lumbra?

Lumbra was founded in 2025 by Aaron Brown and Michael Hiebert. The company operates from Washington, DC, and New York City.

“The organizations that get agents right will spend less time telling them what to do and more time deciding what they may touch and what their work must prove,” said Aaron Brown, co-founder and CEO of Lumbra. “Thousands of agents working a question together can find an insight while there’s still time to act on it.

Market and Business Growth

Lumbra began working in environments with strict security and operational requirements. It signed its first contract with a US intelligence agency two months after product development began.

Under a later Department of War contract, the company moved from contract award to production on the department's top-secret networks within six months.

The company is now looking to apply its technology and experience to enterprise customers that need to manage AI agents across sensitive workflows.

What Happens Next?

Lumbra plans to grow its engineering, product, go-to-market and deployment teams while expanding into regulated commercial markets.

Its focus will be on helping organisations deploy AI agent networks with the controls, monitoring and audit trails needed to operate reliably in sensitive environments.
