As one of Facebook’s first product designers, Soleio co-invented the Like Button and helped create a new kind of craft, where design wasn’t decoration, but direction. Later, he led design at Dropbox, transforming it into one of Silicon Valley’s most admired creative engines. Today, he invests in and advises design-first companies like Figma, Perplexity, and Delphi, continuing to shape how modern product teams think and build.
In Episode 3 of The Library of Minds, Soleio explores the eternal tension between speed and quality, why momentum matters more than perfection, and how cultures of iteration outlast those of control.
He explains how Facebook’s “move fast” mantra worked (and when it didn’t), how design systems can scale clarity without killing creativity, and what 80% of obsolete features taught him about impermanence and progress.
It’s not a story about polish, it’s a study in movement and momentum.
Step Inside Soleio’s Design Mind
For the first time, you can explore Soleio’s thinking directly through his Digital Mind on Delphi. Ask him how he’d solve your own design dilemmas, in his own voice.
Try asking:
How do I decide when to ship versus when to refine?
What does “system-centric design” actually look like day-to-day?
How can I build a culture of speed without burning people out?
This isn’t just a podcast, it’s an open design lab for the modern era.
