Jisi Guo

Design Leader

As VP of Design at Phantom, I built and led the design organization across product design, brand creative, design engineering, and user research. I helped scale the company to 15M+ monthly active users and $20B+ in annual swap volume as Phantom evolved from a crypto wallet into a modern consumer finance platform.

Previously at Lyft, I was a Staff Designer and founding member of the Bikes & Scooters team and Self-Driving platform. During my tenure, I received over 15 design patents.

Prior to Lyft, I was a co-founder of Camoji, a simple GIF camera. We were featured by Apple, downloaded over 1M times, and ranked 4th in the Photo & Video category of the App Store. Camoji was acquired by Lyft in June 2015.

I'm originally from Skokie, a suburb north of Chicago and I studied engineering, economics and design at Northwestern University. On most days, you can find me cycling in the Santa Monica Mountains of Los Angeles.
