Anne Neuberger, former NSA deputy director for cybersecurity and White House cybersecurity coordinator, has signed on as general partner and head of global affairs at Andreessen Horowitz. She argues that technology now sits at the core of geopolitical power, industrial capacity, and national defense. In the Cold War era, innovations like GPS lived inside defense labs under tight government control. By the 2000s, American commercial tech—Windows/Intel, mobile internet—rode global supply chains and underpinned a stable, US-led order. Today’s US-China rivalry has broken apart that model: digital sovereignty, supply-chain resilience and infrastructure trustworthiness have emerged as security priorities. Neuberger says our allies aren’t just buying US gear; they want joint ventures, co-development and shared manufacturing. She lays out two priorities. First, build a common technology foundation from the Pacific to the Atlantic so allies can integrate American innovations in ways that suit local regulations and military goals. Second, push US-aligned AI and other emerging tech at scale. Open-source Chinese models are spreading worldwide; US vendors and startups in defense, aerospace and cyber need global footprints to thrive amid fractured regulations and political headwinds. She points to a recent a16z delegation in Japan, where they met Prime Minister Takaichi, Economy Minister Akazawa, security officials and tech CEOs. Conversations centered on maritime autonomy, AI tools and cybersecurity systems to support Japan’s economic and defense modernization. Neuberger’s message: securing America means building technology partnerships that bind allies into a shared industrial ecosystem—no more one-way sales.
