The son of Iranian and Korean immigrants who met in a New York medical school, he drove from Boston to Silicon Valley after a 1991 Macworld, built foundational consumer internet companies, then returned east to co-found Spark Capital in 2005 - backing Twitter when it had 11 employees, Tumblr before it sold to Yahoo for $1.1 billion, and Discord before it became the home for every online community.
