Summary
Venture capitalist Marc Andreessen has joined the newly reconstituted US Defense Policy Board following an announcement by Secretary of War Pete Hegseth on June 30, 2026. Andreessen, the co-founder and general partner of Andreessen Horowitz (a16z), one of the nation's largest venture capital firms, was among 15 members appointed to the advisory committee that provides independent strategic counsel to Pentagon leadership on defense modernization, strategy, and national security matters.
The Defense Policy Board, originally established in 1985, underwent reconstitution with Ambassador Robert Lighthizer assuming the role of Chair. Lighthizer previously served as U.S. Trade Representative from 2017 through 2021, bringing trade policy expertise to a board now oriented toward defense strategy. Former Senator Norm Coleman was named Vice Chair. The board's formal mandate centers on delivering strategic recommendations to the Secretary of War on critical defense and national security priorities.
Andreessen's appointment marks a significant shift in the composition of Pentagon advisory structures by elevating technology sector leadership into defense policy formulation. Beyond his venture capital role, Andreessen is recognized as the co-creator of Mosaic, one of the first widely adopted web browsers developed in the early 1990s. His firm, a16z, commands substantial influence across the technology ecosystem—the firm raised 18% of all U.S. venture capital dollars deployed in 2025, reflecting its central position in capital allocation across emerging technology sectors and defense-adjacent investments.
The broader Defense Policy Board membership reflects intentional diversity of backgrounds, drawing from policy specialists, military professionals, and private sector leaders. Additional appointees include Michael N. Anton, Rachel A. Bovard, Tom P. Feddo, Mike J. Garcia, Kenneth P. Jones, Blake G. Masters, Daniel P. McCarthy, Michael P. Pillsbury, retired Admiral Chas A. Richard, Francis P. Sempa, Christopher A. Williams, and Theo J. Wold. The inclusion of technology venture capital leadership alongside traditional defense establishment figures suggests a strategic pivot toward integrating private sector innovation frameworks into Pentagon strategic planning.
