AI Startup ASI Raises $325M at $3B Valuation
Boston AI startup ASI raised $325M at a $3B valuation in a Spark Capital-led Series C, building AI that forecasts disruptions across air traffic and power grids.
On Tuesday, Boston-based AI startup ASI said it had raised $325 million in a funding round that values the company at $3 billion. The Series C round was led by Spark Capital, with participation from Citadel Securities, Meritech Capital, Craft Ventures, Energy Impact Partners and Andreessen Horowitz, the company announced. ASI was previously known as Air Space Intelligence Inc., according to Bloomberg.
What ASI does
ASI builds simulation and monitoring software that helps operators forecast disruptions hours, days or weeks ahead. Its AI models are used across air traffic, power grids, logistics and military operations. Founder and CEO Phillip Buckendorf says the company's focus is different from most of the AI industry: "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," he said.
Big government contracts behind the raise
The funding follows two major contract wins. In October, ASI secured a five-year, $99 million US Army contract. In June, it won a 12-year, $875 million Federal Aviation Administration contract covering air traffic management systems. The deals cover military command systems and air traffic management, according to Reuters.
What the money is for
ASI said it will use the new funds to expand deployments in energy, logistics and military environments. The company also plans to grow its research and engineering teams in Boston.
Why it matters
The round shows strong investor appetite for AI software used in real-world applications - not chatbots, but systems that run physical infrastructure. Defense and aerospace AI startups are attracting record interest from both governments and venture funds, and ASI's $3 billion valuation puts it near the top of that wave.
