#497 From Startup Grind to Mozilla Labs: Raj Singh on AI, Vibe Coding, and Building What Matters

Raj Singh, VP of Product at Mozilla and a seasoned startup founder, joins The CTO Show with Mehmet to share a candid look into the evolution of building products—from the early days of AI to today’s GenAI-fueled solo founder wave. We dive into what vibe coding means, how big companies like Mozilla are tackling zero-to-one innovation, and why most startups fail—not because of the idea, but because the founders get tired. 🚀 Key Takeaways • Most startups fail in the messy middle, not the beginning or end • AI is shifting us from “doing the work” to “instructing the machine” • Vibe coding is enabling faster product iteration—but it still needs human judgment • Large companies often struggle with zero-to-one because of talent structure, risk aversion, and short conviction windows • Solo founders can thrive—if they manage their energy and support systems ⸻ 🎯 What You’ll Learn • How Raj defines product-market fit in the GenAI era • The new role of engineers and creators in the age of AI • How to build new products inside legacy organizations • When and how to pivot—without burning out • Why AI shouldn’t be the pitch—it should be the enabler 👤 About the Guest Raj is the VP of Product at Mozilla, leading new 0 to 1 product initiatives.
