Jonathan GuzmanDesigner at Phloe
I am a product designer in San Francisco, shaping 
Phloe, an iOS study app I co-founded. Previously, 
Quizlet and 
1Flow (YC W22).
I’m interested in understanding what people want, need, and expect, and translating that into flows, micro-interactions, and interfaces.

“Jonathan designed the UI for two apps I built, and both times he elevated the product well beyond what I could have achieved alone. Honestly, he designs in his sleep.”
Chris CorderoiOS Software Engineer at Yahoo“I was impressed by Jonathan’s ability to generate multiple iterations and seek feedback on how to improve them.”
