    Y Combinator, Socialcam, and Justin.tv

    Hello, my name is Michael Seibel. I am 36 years old and have lived and worked in the Bay Area for the past 10 years. Currently, I work at Y Combinator as a full-time partner and CEO of the YC accelerator program.


    Previously, I was a co-founder and CEO of Justin.tv from 2007 - 2011 and the co-founder and CEO of Socialcam in 2012. During 2012, Socialcam participated in Y Combinator, raised angel financing from a group of amazing investors, and sold to Autodesk Inc. for $60m (link). Needless to say - it was a busy year. In 2014 Justin.tv became Twitch Interactive and under the leadership of Emmett Shear and Kevin Lin sold to Amazon for $970m.


    Before getting into tech, I spent a year as the finance director for a US Senate campaign and before that I graduated from Yale University with a bachelors degree in political science. Today I spend the large majority of my free time cooking, reading, traveling and going for long drives. I live in San Francisco, CA with my amazing wife Sarah and our son Jonathan.
