Spenser founded Amplitude in 2012 to revolutionize the way companies interact with their mobile users. He and co-founder Curtis Liu completely rebuilt the mobile user analytics stack, creating a behavioral analytics engine that would finally allow companies to easily understand what their users are doing in their applications. Spenser first discovered the need for a better mobile analytics solution while founding Y Combinator startup Sonalight, a voice recognition app, which led to his idea for Amplitude. Prior to Sonalight and Amplitude, Spenser worked as an algorithmic trader for DRW Trading Group and also explored a few smaller startup ideas. He has a B.S. degree in Bioengineering from MIT and is a two-time winner of MIT’s largest programming competition, Battlecode.
