Xiaohan Shen

Xiaohan Shen is the co-founder and CEO of Coldreach (YC W23), a San Francisco startup that uses AI to find ready-to-buy leads by watching public buying signals and to personalize cold outbound at scale. A University of Wisconsin-Madison computer science and data science grad, he calls himself an 'outbound nerd' after writing more than 1,000 cold emails by hand at his first startup, EasyJobs, which he and co-founder Hankel Bao grew to 20,000 monthly active users before pivoting into the tooling problem they lived themselves.
