David Liu

Founder and CEO

DAVID LIU is the founder and CEO of Deltapath. He drives the company’s vision, strategy, and growth; spearheads its technical strategy; and leads a team of world-class engineers to keep Deltapath at the forefront of the industry.

At 14, David began exploring telecom technology with his home telephone and hi-fi radio. He connected the two to mimic enterprise system features such as music-on-hold, call recording and radio broadcast over the telephone line. As the internet grew in significance, he was determined to bridge traditional telephone technology with the new network. He founded Deltapath in 2001 and developed the first-generation SIP based telephone system. The software lets business communication systems work over the internet, simplifying set up and reducing costs for businesses.

David graduated magna cum laude from Santa Clara University in 2004 with a bachelor of science in commerce. In 1998, he completed a program in computer science at Harvard Extension School. David is a member of Beta Gamma Sigma, an honor society for business students and graduates at the top of their class.
