Joonseo Chang

Architecturally vast yet ultimately incoherent systems that give only but the illusion of solvency. I strive to translate these complex systems into beautifully natural interactions.


I'm currently building The Student Computer Company with my buddy Jihoon where we craft delightful AI tools.


I was the sole analyst at Han River Partners, working directly under the MP Chris Koh, co-founder of Coupang (NYSE: CPNG).


Most recently, I was running experiments at Mobbin as a growth engineer, expanding its student and startup programs.


I was also a country lead for the Perplexity campus partnerships program, where I spearheaded the ac.kr Project.


Through sheer dumb luck, I was the first Korean to receive research grants from the teams at Neo and the 1517 Fund.


You can probably find me arguing with members of my college debate society, filming something, or annoying friends with the latest dad joke I found.
