Astronara applies AI to satellite and space data \u2014 a reminder that AI doesn\u2019t stop at software.Snowflake (San Mateo). Snowflake\u2019s data cloud has become central to building and running AI applications.Powering agentic AI at enterprise scaleHow Writer and Premji Invest see the future of agentic AI: full-stack systems, adaptive models, and IT-business collaboration at scale.AI Accelerator InstituteSandesh PatnamVertical AI (where failure is not abstract)The cherry on the cake. This is where you\u2019ll find the headlines driving Wired\u2019s magazine sales. Some of the most demanding AI work happens far from chat interfaces, and it’s about to get very interesting.Waymo (Mountain View). Waymo applies AI to autonomous driving, where reliability matters more than novelty.Figure AI (Sunnyvale). Figure develops general-purpose humanoid robots designed to operate in physical environments.Neuralink (Fremont). Neuralink explores the quite revolutionary world of brain\u2013computer interfaces, blending AI with neuroscience.Anduril Industries (Palo Alto).

It\u2019s no longer about who trains the biggest model. It\u2019s about who can build systems that run reliably, under real constraints, with real consequences.That\u2019s why Silicon Valley still matters, not as the only AI hub, but as one where every layer of the stack collides in practice.Catch AI leaders at Agentic AI Summit Silicon Valley, April 14Catch companies like OpenAI, NVIDIA, and Meta at Agentic AI Summit Silicon Valley.350+ engineers, builders, and tech execs connect to discuss infrastructure, model ops, tooling, and scaling challenges in production.Find out more<\/p>\n","protected":false},"excerpt":{"rendered":"
