Lumbra, a company developing an operating system for AI agents in sensitive and high-security environments, has raised $25 million in Series A funding.

The funding round was co-led by Point72 Ventures and Ansa, with continued participation from Costanoa.

Lumbra will use most of the new capital to hire engineers and expand its deployment teams. The company plans to bring its AI agent platform into regulated commercial industries, helping businesses build reliable, scalable and secure AI-powered workflows.

“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. Lumbra exists to give a decision-maker an advantage at the moment of decision.”

The company already has AI agents operating on top-secret networks across the Pentagon and the U.S. Intelligence Community. Lumbra signed its first contract with a U.S. intelligence agency just two months after starting product development. It later deployed its technology on the Department of War’s top-secret networks within six months of receiving a contract.

The Pentagon also identified Lumbra as one of two companies supporting its Agent Network project, which is part of the Department of War’s AI Acceleration Strategy.

Lumbra aims to solve a major challenge in enterprise AI adoption: making AI agents reliable, controllable, and easy to monitor. Its technology allows organizations to track what AI agents do, understand how they reach conclusions, and ensure sensitive information remains protected.

The company’s platform, LumbraOS, supports different AI models, including advanced commercial and open-source models. It includes three main products:

• Nebula: Coordinates AI agents, tracks their actions, connects their findings to original sources, and enforces data protection rules.
• StarChart: Creates an organizational knowledge graph where AI agents store information, insights, and conclusions with their sources and security labels.
• Astrolabe: Tests AI agents before deployment and continuously evaluates their performance using customized benchmarks.

Founded in 2025 by former CIA officer Aaron Brown and MIT-trained engineer Michael Hiebert, Lumbra is headquartered in Washington, D.C. and New York. The company has more than 40 employees and is expanding its technology beyond government applications into regulated commercial markets.
