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