Marlinspike Partners

Marlinspike is a veteran-led, Washington D.C.-based venture capital firm investing in 'dual-use' technologies that solve national security challenges and create innovative commercial applications. The firm believes that superior technology is the best source of security, and that there is both profit and purpose in funding best-in-class aerospace and defense innovations. It focuses on four core industries: Artificial Intelligence & Data Analytics, Autonomy & Robotics, Aerospace, and Cybersecurity. Marlinspike's dual-use mandate requires that portfolio companies address hard national security problems and possess a credible path to large-scale commercial markets. The firm takes a private equity-style, hands-on approach post-investment—helping founders navigate defense procurement, government partnerships, and commercial scaling. It leverages deep connectivity to the Intelligence Community (particularly the CIA via In-Q-Tel), the Department of Defense, and Silicon Valley to source and support companies that will 'rearm and rebuild' the U.S. defense industrial base.
