Two firms highlighted in this summary of venture activity in the market describe their plans for investing in more businesses, while a manufacturing startup takes the next step in its “factories-as-a-service” strategy.
Andreesen Horowitz
This mainstay of venture capital has collected $15 billion in new capital from investors at a figure equal to 18% of all VC dollars allocated in the U.S. in 2025, co-founder Ben Horowitz wrote in a blog post published Friday.
Roughly $1.2 billion of that will go into American Dynamism, a fund dedicated to investments in areas where the U.S. government is either a customer or key stakeholder.
Andreessen Horowitz’s highest-profile defense tech investments have included Anduril, Saronic, Shield AI, SpaceX and Hadrian. More on Hadrian in the next section.
In conjunction with the raise, the firm, commonly called a16z, has also signed on as a technology acceleration partner for Booz Allen Hamilton in the government market. Booz Allen will work with a16z-backed companies on technology development initiatives in areas such as artificial intelligence, autonomy and electronic warfare.
Hadrian
This automation technology startup has completed a new investment round that pushes its touted valuation to roughly $1.6 billion, only six months after completing a $260 million Series C raise.
Hadrian did not disclose the amount of expanded capital it fetched in this round, which was led by T. Rowe Price Associates. The list of participants includes a16z, Altimeter Capital, Construct Capital, D1 Capital Partners, Founders Fund, Lux Capital, StepStone Group and 1789 Capital.
Founded in 2020, Hadrian provides what it calls a “factories-as-a-service” model for other defense companies to scale their manufacturing facilities up and down according to demand. The company is pushing artificial intelligence and robotics as tools for automating many phases of the component manufacturing process.
Hadrian will use the new capital to accelerate factory expansion efforts, scale workforce training programs and continue investing in its technologies.
Valinor Enterprises
This operational holding company focused on defense and government technology has collected $54 million in Series A capital, a figure that brings its total amount of external investment to $85 million.
Valinor is at work in building new product companies in domains such as military construction and infrastructure, munition lifecycle management and maritime support systems. The firm aims to launch those businesses this year and make further acquisitions to further build them out.
Valinor’s current investments include areas such as mobile medical systems, smart optics, charging nodes, data ingestion software and unmanned aerial systems.
The Series A round was led by Friends & Family Capital, the venture capital firm co-founded by former Palantir CFO Colin Anderson and veteran investor John Fogelsong.
General Catalyst, Founders Fund and Red Cell Partners are among the existing investors continuing their involvement. The list of new investors includes Fifth Down Capital, Narya and XYZ Venture Capital.
