ASI, formerly known as Air Space Intelligence, has secured $325 million in Series C funding. The Boston-based company, which specializes in advanced artificial intelligence, is now valued at $3 billion.
Investors participating in this round include affiliated companies of Citadel Securities, Meritech Capital, Craft Ventures, Energy Impact Partners, and Andreessen Horowitz. ASI develops AI tools for managing complex physical infrastructure, enabling operators to predict and prevent failures.
The company does not focus on text generation; instead, it creates systems that simulate and optimize physical processes. Founder and CEO Philip Backendorf stated that critical infrastructure requires more sophisticated management tools to handle growing complexity, describing ASI as the automatic nervous system for America's vital operations. The new funding will allow the company to scale its technologies across several high-risk sectors.
Many essential systems are experiencing increasing operational pressure. Aviation networks must manage safety risks and overloads, while power grids must ensure reliable service amid rising demand. Military logistics also demands coordination across interconnected assets.
ASI's technology uses continuous forecasting to address these challenges. The systems model potential outcomes hours, days, and weeks ahead, combining deterministic and probabilistic modeling to support planning and operational forecasting. This approach helps operators shift from reactive problem-solving to early risk assessment and analysis of potential responses within complex networks, while also providing multi-dimensional monitoring and optimization.
ASI has secured significant government contracts in transportation and defense. The U.S. Department of Transportation and the Federal Aviation Administration awarded the company an $875 million contract supporting the modernization of the National Airspace System. The company also collaborates with the U.S. Army, U.S. Air Force, and Pacific Command. The Army recently provided ASI with a $99 million contract to support modernized command and control capabilities, including the 'Next Generation Command and Control' program.
Furthermore, ASI supported over 4,000 Air Force operators during Operation Epic Fury. These deployments demonstrate the company's presence in demanding operational environments. However, further expansion will depend on performance, reliability, and successful project execution.
General Partner Clay Fisher of Spark Capital characterized ASI as a company creating a new category of AI infrastructure, pointing to government contracts and commercial adoption as proof of demand. ASI's client base extends beyond government agencies.
Among its commercial clients in civil aviation are Delta Air Lines, Alaska Airlines, and United Airlines, integrating the company's technology into the operations of major airlines. Energy is another key growth area. National Grid partnered with ASI for power grid planning and operation. This utility supplies natural gas and electricity to over 20 million people in the northeastern US. The growing electricity demand presented a significant opportunity for Energy Impact Partners.
The firm's next task will be implementing solutions in sectors with diverse needs and requirements, including aviation, energy, and defense. Scaling deployments will require performance guarantees and close coordination with clients. The $325 million raised will provide ASI with the additional capacity to execute these plans, helping to demonstrate whether predictive AI can deliver long-term value to critical infrastructure.
