ASI, formerly known as Air Space Intelligence and headquartered in Boston, builds simulation and monitoring software that helps operators forecast disruptions across complex systems including air traffic networks, power grids, and military logistics. The platform is designed to run continuously, modeling how a system might behave under a range of future conditions so operators can anticipate failures before they occur rather than react after the fact. The company targets three core verticals: aviation, energy, and military operations.
Led by Spark Capital, with participation from affiliates of Citadel Securities, Meritech Capital, Craft Ventures, Energy Impact Partners, and Andreessen Horowitz.
The $3 billion valuation on this round places ASI among the most highly valued infrastructure-AI startups of 2026 and signals that venture capital is increasingly flowing toward predictive, always-on AI tools embedded in critical infrastructure rather than general-purpose generative models. ASI intends to use the proceeds to expand deployments across energy, logistics, and tactical-edge environments while growing its Boston engineering team, pointing to a near-term increase in AI software penetration across sectors, including power grids, that directly affect data center operations and grid reliability. The participation of crossover investors alongside traditional venture firms reflects growing institutional appetite for defense- and infrastructure-adjacent AI at scale.
