ASI, the frontier AI company orchestrating critical infrastructure and national security, today announced a $325 million Series C financing round valuing the company at $3 billion. The financing is led by Spark Capital, with major participation from affiliates of Citadel Securities, Meritech Capital, Craft Ventures, Energy Impact Partners, and Andreessen Horowitz (a16z).

ASI builds AI for America’s critical infrastructure, modeling the future hours, days, and weeks ahead, giving operators the foresight they need where it matters most.
“The future of our national prosperity hinges on giving the people who run our critical systems the power to out-calculate compounding complexity in an increasingly dynamic world,” said Phillip Buckendorf, Founder and CEO of ASI. “While the broader tech ecosystem spent hundreds of billions teaching AI to manipulate words and generate text, ASI is deeply focused on AI systems that can manage and control physical assets — no matter if that’s a plane, a vessel, or the energy grid. This capital ensures ASI scales as America’s engine: the automated nervous system keeping the country running.”
America currently runs on systems operating at or beyond their design limits: failing air traffic control systems, heavily congested electrical grids, and globally contested defense logistics. Today, managing this infrastructure remains deeply manual and reactive, fundamentally constrained by what human operators can track on a single screen in the present moment. ASI changes the operating principles of entire industries by giving operators the full picture and foresight into what happens next. Through continuous forward simulations, multidimensional monitoring, and optimization, ASI models the future hours, days, and weeks ahead while balancing deterministic and probabilistic modeling to ensure reliability and accuracy where it matters most. This shifts critical sectors from reactive triage to predictive, system-wide orchestration before problems arise.
ASI’s AI systems are already deployed across America’s highest-stakes operations:
- National Transportation: The U.S. Department of Transportation and Federal Aviation Administration awarded ASI an $875 million program of record to modernize the National Airspace System. ASI is one of only four technology companies founded since 2000 to win a federal program of record of this magnitude. And no company has accomplished this faster.
- National Security: ASI is deployed across the Department of War with the U.S. Army, U.S. Air Force, and U.S. Pacific Command. ASI is the fastest-growing software platform across the U.S. Air Force, supporting over 4,000 operators during Operation Epic Fury. The U.S. Army recently awarded ASI a $99 million contract to scale its technology across the Army’s modernized command and control efforts, including the Next Generation Command and Control (NGC2) program.
- Critical Commercial Sectors: ASI’s systems actively orchestrate operations for major airlines such as Delta Air Lines, Alaska Airlines, and United Airlines. National Grid, a publicly traded utility that provides natural gas and electricity to more than 20 million people in the Northeast U.S., has partnered with ASI to deploy its technology for electric grid planning and operations.
“ASI represents a generational category creator: an AI company running the physical world and orchestrating its most valuable assets,” said Clay Fisher, General Partner at Spark Capital. “Securing an $875 million federal program of record alongside rapid commercial adoption across airlines and power networks proves that ASI is sovereign infrastructure. ASI is one of just four neoprimes that have signed production contracts of this size with the U.S. government.”
“Some of the most valuable applications of AI will be in complex, real-world systems where thousands of interconnected assets must be continuously modeled and optimized,” said Michael Robinson, Partner at Craft Ventures. “ASI’s work with the FAA and recent $99 million U.S. Army contract are clear examples of the company’s impact on aerospace and defense, but the same underlying technology is already demonstrating its value across energy and logistics, making ASI the decision intelligence platform for these critical industries.”
“Electricity demand is rising at an unprecedented pace, and utilities are tasked with upgrading the grid while maintaining a high level of reliability,” said Sameer Reddy, Managing Partner, Flagship at Energy Impact Partners. “Mission-critical institutions already trust ASI to run some of the country’s most complex operations, and that same technology now helps utilities like National Grid get ahead of disruption, from how they respond to storms to how they plan and invest for what’s next. We see energy as a major growth opportunity for the company.”
“The institutions behind America’s most critical systems trust ASI to show them what is coming next and what to do about it,” said Anthony DeCamillo, Head of Growth Investing at Citadel Securities.
The Series C capital will accelerate deployment across energy, logistics, and tactical edge environments, while expanding ASI’s frontier AI research and engineering teams headquartered in Boston.
About ASI
ASI is the frontier AI company orchestrating critical infrastructure and national security. ASI’s world models and reasoning systems simulate physical operations hours, days, and weeks ahead, so the people running air traffic control, the electric grid, and military operations can catch problems early and act before they spread. ASI’s systems already power many of America’s most important institutions, such as the Department of Transportation, United Airlines, Delta Air Lines, the U.S. Army, the U.S. Air Force, and National Grid. ASI is headquartered in Boston with offices in Washington, DC, Denver, and Europe, and is backed by leading investors, including Andreessen Horowitz and Spark Capital.
