ASI raises $325M Series C, hits $3B valuation

Its AI manages physical infrastructure like air traffic and power grids, betting government contracts outpace chatbots as AI's next big market.

• ASI, the Boston AI startup formerly known as Air Space Intelligence, raised $325 million in a Series C round led by Spark Capital, valuing the company at $3 billion.
• The company builds simulation and monitoring software that helps operators forecast disruptions hours, days or weeks in advance across complex systems like air traffic, power grids and military operations.
• ASI already holds a 12-year, $875 million FAA contract from June to modernize the National Airspace System and a five-year, $99 million US Army command-and-control contract won this month.
• The new funds will expand ASI's research and engineering teams in Boston and fund deployments in energy, logistics and military environments.
• The round makes ASI the Boston area's most valuable AI startup, surpassing Liquid AI, and adds to a local AI resurgence that includes Suno, Blitzy and new Anthropic and Harvey offices.
• ASI's bet on AI that controls physical assets rather than generating text reflects a widening investor appetite for real-world AI applications beyond large language models.
