From Game Engines to National Lab Simulations

Martin Casado has lived through multiple tech waves—first as a founder, now as a16z’s leading voice on AI and infrastructure. He helped pioneer software-defined networking, then moved from academia to entrepreneurship, and today backs founders building at the frontier of technology as a General Partner at Andreessen Horowitz. In this conversation, Martin shares his unique perspective on the AI boom, his market-first investment philosophy, and why he believes we’re still in the early days of AI’s impact.

We explore:

• Martin’s path from game engines and simulations to investing at Andreessen Horowitz

• Why Martin believes we’re only in “1996” of the AI boom cycle with years to run before any bubble

• Why Martin approaches investing “from markets in” rather than “from companies out”

• Why the AI coding market represents a potential $3 trillion opportunity

• The transformation of Andreessen Horowitz from a small generalist partnership to a specialized 600-person organization

• The concerning dominance of Chinese companies in open source AI models

• Why Martin thinks AGI discussions encourage “lazy thinking” and obscure meaningful conversations

• How World Labs is solving the 3D representation problem that could unlock robotics, VR, and more
