Mark Spencer

Founder and Chairman of the Board

Mark Spencer revolutionized digital telephony in 1999, when he created Asterisk—the world's first open source telephony platform. Running a tech support company at the time, and faced with proprietary, expensive telephony solutions, Mark used his knowledge of the open source Linux operating system, computer engineering, and programming to build his own telephony platform. And thus Asterisk was born.

Widely seen as a technology leader, in 2006 Mark was featured in a Forbes Magazine article “Dial ‘D’ for Disruption” and also gives keynote speeches around the world on technology and entrepreneurship.

Mark was Digium's CEO from 1999 to 2007 and currently serves as its Chairman of the Board. An aviation enthusiast, Mark also runs Avilution which makes aviation software for mobile devices.
