Marlinspike Partners, a venture capital firm focused on dual-use technologies, has successfully closed its second fund at $127 million. The oversubscribed Marlinspike Disruptive Technology Fund II surpassed its initial $75 million target. This capital will be deployed into early-stage companies developing technologies critical to national security and the American industrial sector.


A Strategic Response to Global Challenges

The fund's closure arrives at a pivotal moment defined by increasing global instability and rapid technological advancement. The race for leadership in artificial intelligence and robotics is intensifying, reshaping both commercial and defense landscapes. These dynamics underscore the urgent need for strategic investments to secure a prosperous future for the United States.

Marlinspike's core mission is centered on "Rearming and Rebuilding America" for this new era. The firm believes a strong American military and a robust economy are intrinsically linked and mutually reinforcing. Fund II is designed to support this vision by backing companies that enhance both national defense and domestic industrial strength.

A key focus is revitalizing the U.S. industrial base to regain global manufacturing leadership. As AI and robotics transform industrial output, domestic production gains significant strategic value. Marlinspike's investments aim to bolster this shift, thereby enhancing America's security and economic resilience.

Investing in Technological Dominance

Neil Keegan, Co-Founder and CEO, emphasized the firm's belief in maintaining American technological superiority. He stated Fund II deepens their commitment to founders building technologies that address immediate defense needs while scaling into large commercial markets. This high-conviction strategy involves taking decisive action to shape future industrial leadership.

Mislav Tolusic, Managing Partner and CIO, articulated a vision of a world transitioning from human-centric to autonomy-centric operations. He noted that while the internet did not fundamentally alter manufacturing, AI is transforming core industrial processes. This transition is expected to drive significant acceleration in U.S. GDP growth in the coming years.

The implications of this technological shift for national security and economic prosperity are profound. According to Tolusic, nations that master AI-enabled design, manufacturing, and autonomous systems will build faster and compete more effectively. These nations are poised to lead the next industrial era, guiding Marlinspike's investment decisions.

Fund II Profile and Investor Confidence

The oversubscribed $127 million fund will continue Marlinspike's strategy of investing in early-stage companies in the United States and allied nations. The firm targets businesses operating at the intersection of national security and next-generation industrials. Key sectors of interest include artificial intelligence, autonomous systems, and advanced manufacturing.

Marlinspike's portfolio already includes notable companies such as Anduril Industries, Armada, and JetZero. Fund II builds upon this strategy with new investments in firms like Layup Parts and BrightAI. These companies exemplify the firm's focus on the convergence of AI, autonomy, and advanced manufacturing.

The new fund attracted strong support from legacy investors and prominent new institutional partners. Key backers include notable family offices and the Fairfax County Employees' and Police Officers Retirement Systems. Katherine Molnar of the Fairfax system expressed a shared constructive outlook on the opportunities across autonomy and AI.


The successful closing of Marlinspike Disruptive Technology Fund II marks a significant step in the firm's mission to fortify American leadership. By channeling $127 million into dual-use technologies, Marlinspike is investing in the companies shaping the future of defense and industry. This strategic focus positions the firm as a key player in ensuring national security.
