Guillermo Rauch is the founder and CEO of Vercel, creators of v0 (one of the most popular AI app building tools), and the mind behind foundational JavaScript frameworks like Next.js and Socket.io. An open source pioneer and legendary engineer, Guillermo has built tools that power some of the internet’s most innovative products, including Midjourney, Grok, and Notion. His mission is to democratize product creation, expanding the pool of potential builders from 5 million developers to over 100 million people worldwide.

In this episode, you’ll learn:

1. How AI will radically speed up product development—and the three critical skills PMs and engineers should master now to stay ahead

2. Why the future of building apps is shifting toward prompts instead of code, and how that affects traditional product teams

3. Specific ways to improve your design “taste,” plus practical tips to consistently create beautiful, user-loved products

4. How Guillermo built a powerful app in under two hours for $20 (while flying and using plane Wi-Fi) that would normally take weeks and thousands of dollars in engineering time

5. The exact strategies Vercel uses internally to leverage AI tools like v0 and Cursor, enabling their team of 600 to ship faster and better than ever before

6. Guillermo’s actionable advice on increasing your product quality through rapid iteration, real-world user feedback, and creating intentional “exposure hours” for your team
