Here is everything you need to know about the round, the investors, and what Hadrian actually does.

Investors: A Who's Who of Defense Tech and Wall Street

Hadrian's Series D attracted a sprawling syndicate of investors, mixing traditional growth equity firms, crossover funds, long-only public managers, and strategic banking partners.

Anchor co-lead: JPMorgan Chase's Strategic Investment Group anchored the round through the bank's $1.5 trillion, 10-year Security and Resiliency Initiative .

Co-lead investors: WCM Investment Management, Washington Harbour Partners, Valor Equity Partners, 137 Ventures, and Baillie Gifford co-led the financing .

Other participating investors: Andreessen Horowitz (a16z), Founders Fund, Lux Capital, Altimeter Capital Management, 1789 Capital (where Donald Trump Jr. is a partner), Morgan Stanley Wealth Management, funds managed by Apollo and T. Rowe Price, and CapitalG .

Total Capital Raised to Date

Hadrian has raised approximately $1.7 billion in total equity funding across all rounds, including its $260 million Series C in July 2025 (led by Founders Fund and Lux Capital), a $117 million Series B in December 2023 at roughly a $500 million valuation, and a $90 million Series A in March 2022 . Some sources estimate total funding exceeds $1.9 billion when including certain extensions and debt-like instruments .

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

Hadrian is not trying to build new weapons, drones, or AI-piloted systems. Instead, it builds highly automated, AI-powered manufacturing facilities that mass-produce precision parts for the military vehicles the Pentagon already operates .

Its core proposition is that manufacturing is a software problem. Hadrian operates under a "factories-as-a-service" model: defense primes like Lockheed Martin, RTX, and Anduril — and the Pentagon itself — can buy production capacity without building their own plants .

Opus: The Software Brains

The company's proprietary software platform, Opus, handles scheduling, tool routing, robotics orchestration, and automated quality control across factories. Hadrian says the system can cut lead times from months to days .

Key Focus Areas

• Submarine components: In March 2026, Hadrian opened Factory 4 in Cherokee, Alabama — a 2.2-million-square-foot advanced manufacturing facility built in a public/private partnership with the U.S. Navy. The facility is designed to mass-produce components for Virginia-class attack submarines and Columbia-class ballistic missile submarines . The deal for that facility, combining more than $1.5 billion in private capital with $900 million in Navy funding, was valued at $2.4 billion .
• Aerospace and defense hardware: Hadrian also produces parts for munitions, aviation, autonomous systems, and shipbuilding .

Workforce and Scale

CEO Chris Power told reporters the company plans to grow its workforce from 700 to over 2,000 employees in the next year . Hadrian claims it can train workers with no manufacturing experience to achieve output levels ten times that of traditional factory workers within 30 days . The company operates nearly 3 million square feet across four sites .

Customers

Hadrian's customers include the Pentagon, Lockheed Martin, RTX, and Anduril . The U.S. Navy has directly contracted Hadrian to mass-produce submarine parts under a $900 million contract funded by the reconciliation bill .

Why This Matters

Hadrian's massive raise signals a critical shift in venture capital toward modernizing the physical defense industrial base, rather than just funding software or drone startups. By applying AI, robotics, and software orchestration to the unglamorous but essential work of machining precision parts, Hadrian is betting that the bottleneck in U.S. defense production is not a lack of ideas — it's a lack of factory capacity.
