Summary
Venture capitalist Marc Andreessen has been appointed to the newly constituted US Defense Policy Board, according to an announcement by US Department of War Secretary Pete Hegseth on June 30, 2026. The appointment places one of Silicon Valley's most influential technology investors in a senior advisory role within the Pentagon's policy apparatus, signaling increased institutional alignment between the venture capital and defense sectors.
The Defense Policy Board comprises 15 members tasked with providing independent strategic advice to senior department leadership on defense strategy, modernization, and national security. Ambassador Robert Lighthizer, who served as US Trade Representative from 2017 to 2021, chairs the board. Former Senator Norm Coleman serves as vice chair. Beyond Andreessen, the newly appointed members 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—a cohort drawn from policy, military, and public service backgrounds.
Andreessen's appointment is notable for positioning a technology venture capitalist in defense policy advising rather than a traditional military or diplomatic figure. As co-founder and general partner at Andreessen Horowitz, one of the largest venture capital firms globally, Andreessen brings institutional technology sector perspective to Pentagon deliberations. His background includes co-creating Mosaic, one of the world's first widely used web browsers during the early 1990s internet expansion, establishing his credentials as a technology pioneer with deep sector networks.
The composition of the Defense Policy Board reflects a broader institutional trend toward incorporating technology sector expertise into federal defense strategy and modernization planning, particularly as cyber capabilities, artificial intelligence, and advanced systems increasingly shape military doctrine and procurement priorities.
