Terayon Communication Systems, Inc. was a company that vended equipment to broadband service providers for delivering broadband voice, video and data services to residential and business subscribers.

He taught for a while at Tel Aviv University’s computer science faculty, and then joined Helios.

After Helios was sold to Cadence Design Systems, Zaki moved to the US, and urged his brother to join him and set up the company.

During 1999 and 2000 the company acquired seven other companies, including: Imedia, a video processing startup founded by Efi Arazi (founder of Scitex) for $100m; Radwiz for $64m from the Rad Group, Teledata Networks (which was later sold) [3] and Ultracom Communications for $32m in March 2000.

In April 2006, Terayon was delisted from NASDAQ due to outstanding financial reports.
