Kevin Tian

Kevin Tian is the co-founder and CEO of Doppel, an AI-native social engineering defense platform that scans the internet for impersonation campaigns and shuts them down automatically. A Georgetown grad who built dispatch systems and flying-car software at Uber and Lyft, he started Doppel in 2022 after spotting social engineering becoming the top source of breaches and cyber-insurance claims. Doppel raised a $70M Series C in November 2025 at a $600M+ valuation, backed by Bessemer, a16z, CrowdStrike CEO George Kurtz, and a bench of WNBA stars.
