Shownotes

What can a dragon painted in a single stroke teach us about software?

Guillermo Rauch is the founder and CEO of Vercel. Growing up in Argentina, he taught himself English in order to teach himself programming, then went on to create Socket.io and other foundational technology for the real-time web. Along the way, he developed a cunning designer’s eye that became the competitive advantage for what is now a multi-billion dollar venture.

In this conversation with Soleio, Guillermo explains why he designed Vercel’s first command line in Sketch before writing any code, why layout shift erodes trust, and why his company won’t commit any “random acts of AI.”

Guillermo makes the case for why he’s not just chief executive. He is also chief designer.
