Michael Seibel is the Chief Executive Officer of Mountain View, California-based startup incubator Y Combinator.

[19]He was previously a Partner at Y Combinator.

[5] [1]

Early Life

Seibel was born in Brooklyn, New York, where he lived until the age of 9.

His family then moved to East Brunswick, New Jersey, where he graduated from East Brunswick High School in 2000.

He has two younger siblings.

Education & Career

After graduating from high school, Seibel attended Yale University, where he was a member of the Yale Political Union and lived in the Bradford residential college.

[-1]He graduated in 2005 with a bachelor's degree in political science.


From October 2005 to November 2006, Seibel worked as the finance director for former President and CEO of the National Association for the Advancement of Colored People and former United States Congressman Kweisi Mfume's 2006 senate campaign.

Mfume, who sought the U.S.

Senate seat of senator Paul Sarbanes (D-MD), lost the race to U.S.

Congressman Ben Cardin.

While working on Mfume's campaign in October 2006, Seibel also started live video streaming company Justin.tv with his friends Justin Kan, Emmett Shear and Kyle Vogt.

Following the end of Mfume's campaign, Seibel moved to Silicon Valley in order to work full-time on Justin.tv with them.

The company launched in the summer 2007 as an online reality television show that broadcast Kan's life at all hours of the day.

After raising funding and joining the portfolios of investors Tim Draper and Alsop Louie Partners, Justin.tv became profitable in fall 2010 and Seibel, Kan, Shear and Vogt began working on two new projects within the company, smartphone video sharing app Socialcam and live video streaming website Twitch.tv.

These projects were eventually turned into full-fledged companies, with Twitch.tv entering management under Twitch Interactive with Shear as CEO and Socialcam participating in Y Combinator's winter 2012 class with founders Seibel, Ammon Bartram and Guillame Luccisano at the helm.

In July 2012, Socialcam was acquired by Autodesk, Inc. for $60 million.

In August 2014, Twitch.tv was sold to Amazon for $970 million.


Currently, Michael serves as the Chief Executive Officer at Y Combinator.

[6]He is the first African-American partner at Y-Combinator and his primary role is to increase minority representation and diversity for the incubator.


Personal Life

Although Michael has enjoyed success throughout his career in Silicon Valley, he has stated "[What keeps me up at night is] Thinking about what I want to be when I’ve grown up...I don’t think the first line of my obituary has been written yet."


He is a father of two children and lives in Berkeley, California with his family.
