ASI, a Boston-based artificial intelligence company developing systems for critical infrastructure and national security, raised $325 million in a Series C funding round at a valuation of $3 billion.
The financing was led by Spark Capital, with participation from affiliates of Citadel Securities, Meritech Capital, Craft Ventures, Energy Impact Partners, and Andreessen Horowitz (a16z).
Founded in 2018 by Phillip Buckendorf, Kris Dorosz, and Lucas Kukielka, ASI, formerly known as Air Space Intelligence, develops AI-powered simulation and decision-support systems for complex physical operations. Buckendorf serves as CEO, Dorosz as Chief Research Officer, and Kukielka as Co-Founder.
The company’s technology uses world models and reasoning systems to simulate operational conditions hours, days, and weeks in advance. Its software helps organisations anticipate disruptions, evaluate possible responses, and optimise operations involving aircraft, transportation networks, energy grids, and military systems.
ASI serves government agencies and commercial organisations across aviation, defense, energy, and logistics. Its customers include the Federal Aviation Administration (FAA), United Airlines, Delta Air Lines, the U.S. Army, the U.S. Air Force, and National Grid.
In October 2026, ASI secured a five-year, $99 million contract with the U.S. Army for command and control systems. This followed a 12-year, $875 million contract awarded by the FAA in June 2026 for software and AI capabilities supporting air traffic management.
The latest financing follows ASI’s $34 million Series B round in December 2023, led by Andreessen Horowitz, with participation from Bloomberg Beta, Renegade Partners, and Spark Capital.
ASI plans to use the new capital to expand deployments across energy, logistics, and tactical military environments. The company also intends to grow its AI research and engineering teams in Boston to support further development of its simulation and operational intelligence technologies.
