Today's guest is David Glick, Senior Vice President of Enterprise Business Services at Walmart. Walmart is one of the world's largest retailers, serving millions of customers through thousands of physical stores and online platforms. David joins Emerj Editorial Director Matthew DeMello to share practical lessons from Walmart's experience building AI at scale. He dives into how Walmart uses small, focused AI "nano agents" to solve specific business problems quickly and effectively, and how a "super agile" development process accelerates collaboration between engineers and domain experts. David also discusses overcoming organizational hurdles to deploy AI solutions rapidly while maintaining security and compliance. David is a featured keynote speaker at the AI Infra Summit, September 9–11, 2025, in Santa Clara. This episode is sponsored by Kisaco Research.
