Episode notes

In this episode, Lucas and Luna dive into the story of Zscaler, the cloud security company that pioneered the zero-trust security model before it became industry standard. They explore how founder Jay Chaudhry bootstrapped the company for the first seven years, turning down venture capital until he had a working product and real customers. The conversation focuses on Zscaler's unique go-to-market strategy: selling to chief information security officers by reframing security as a networking problem, not a feature add-on. Lucas breaks down how Zscaler's 'zero-trust' architecture - which assumes no user or device is inherently trustworthy - flipped the traditional castle-and-moat security model on its head. They also discuss the company's IPO in 2018 and how it reached a market cap of over $30 billion by mid-2026, making it one of the most valuable pure-play cybersecurity firms. The episode closes with a reflection on Chaudhry's contrarian bet and what it means for entrepreneurs building in crowded markets.
