Jeff Seibert (born July 27, 1985) is an American entrepreneur and angel investor. He is best known for co-founding Crashlytics, which in a little over a year was acquired by Twitter for over $100 million in 2013 (later valued at $259.5 million at Twitter's IPO), and co-founding Increo, which was acquired by Box in 2009.[1] [2]

Early life[edit]

Seibert grew up in Baltimore, Maryland. He discovered technology at a young age. He taught himself C in 6th grade and went on to write a range of Macintosh shareware applications. At the age of 13, Jeff released his first application, Histogram, a specialized graphing program for Mac OS. During high school, in 2002, Seibert went on to release EVONE, a graphical editor for the computer game Escape Velocity by Ambrosia Software.[3]


Seibert attended Gilman School in Baltimore, graduating in 2004.

Seibert enrolled as an undergraduate degree student at Stanford University. He majored in Computer Science. At Stanford, Jeff was a Vice President of BASES where he led the Entrepreneurial Thought Leaders series from 2005 to 2008. In 2007, Seibert was selected as a Mayfield Fellow where he studied under Tom Byers and Tina Seelig. Seibert received a B.S. in Computer Science from Stanford University in 2008.[4]


Seibert has been deeply involved in technology since he was young. While at Stanford University, he worked for Apple as a campus representative.

In 2007, Seibert co-founded Increo with Kimber Lockhart. Two years later, in 2009, Box acquired Increo and Jeff led Box's east coast presence.

In 2011, Seibert co-founded Crashlytics with Wayne Chang. In about a year, Twitter acquired Crashlytics for over $100 million (later valued at $259.5 million at Twitter's IPO).[1][2]

In 2014, Seibert led the team that created Fabric, Twitter's mobile developer platform. It launched in October 2014 and as of 2016 is used by over 225,000 developers and installed on over 2 Billion mobile devices.[5]

In September 2015, Twitter announced that it promoted Seibert to oversee Twitter's core product. [6] Nine months later, Seibert returned to his previous role on the Fabric team.[7] On January 18th 2017, Seibert announced Fabric's sale to Google and his plans to step back from his role on the Fabric team.
