Who Led and Participated?

The round featured a sprawling syndicate of top-tier investors, signaling broad confidence in Hadrian's industrial approach to defense tech.

• Co-Leads: The round was co-led by five firms: WCM Investment Management, Washington Harbour Partners, Valor Equity Partners, 137 Ventures, and Baillie Gifford .
• Anchor Co-Lead: JPMorgan Chase's Strategic Investment Group anchored the round, investing via the bank's $1.5 trillion, 10-year Security and Resiliency Initiative .
• Other Notable Participants: The investor list also includes Andreessen Horowitz (a16z), Founders Fund, Lux Capital, 1789 Capital (where Donald Trump Jr. is a partner), CapitalG, Altimeter, and funds managed by Apollo and T. Rowe Price .

Total Funding to Date

Hadrian has raised approximately $1.8 billion cumulatively across seed through the Series D round . Key prior rounds include:

• July 2025: $260 million Series C co-led by Founders Fund and Lux Capital .
• January 2026: An expansion round led by T. Rowe Price at a $1.6 billion valuation .

The Business Model: 'Factories-as-a-Service'

Hadrian's core operation is building and operating highly automated factories — a model it calls 'Factories-as-a-Service' (FaaS) . Instead of just selling parts, it sells production capacity.

• What it Makes: The company produces precision metal components for the military vehicles the Pentagon already relies on. This includes parts for submarines, aircraft, ships, and munitions .
• How it Makes Them: Its factories use AI, robotics, and a proprietary scheduling and routing software platform called 'Opus' to manage the entire production process. Hadrian claims this system can produce parts up to 10 times faster and at half the cost of traditional CNC machine shops .
• Who it Sells To: Defense primes and government agencies buy capacity from Hadrian rather than building their own factories. Its customers include Lockheed Martin, RTX, Anduril, and the U.S. Navy .
• What it Does NOT Do: The company explicitly does not build AI-powered weapons, autonomous drones, or battlefield software. It focuses entirely on manufacturing the physical parts for existing programs .

Case in Point: The Navy's $900 Million Bet

Hadrian's most significant validation came in March 2026, when it opened 'Factory 4' in Cherokee, Alabama, a 2.2-million-square-foot advanced manufacturing facility built in partnership with the U.S. Navy .

• The Contract: The Navy placed a $900 million contract on Hadrian to produce components for its top-priority Virginia-class and Columbia-class nuclear submarines .
• A New Model: Navy Secretary John Phelan described the factory as a different model: "Hadrian does not just machine parts. They build integrated production systems: raw material in, test-ready hardware out. A single system doing what used to require dozens of suppliers" .
• Growth Plan: The company plans to use the Series D funds to expand its workforce from 700 to 2,000 employees and build additional factories focused on munitions and autonomous systems .
