Kelvin Zhang
I'm a designer and engineer focused on building high-craft consumer products. I enjoy making complex systems feel simple and designing around how people actually think and behave.
Currently, I’m building Gleam, a coach for your soft-skills used by more than 350,000 people with over $1M in annual revenue. We’ve raised $3.4M from investors and operators at companies including OpenAI, Ramp, and Tinder.
Previously, I worked on design and engineering at Notion, Arc, and Instagram.
I also write occasionally.
