RAD Group: Breeding Start-Ups and Innovation

The RAD Groups decentralized approach maximizes the advantages inherent in smaller business units - such as flexibility and entrepreneurial spirit - while allowing member companies to share mutually beneficial developments and fostering innovations. - Zohar Zisapel, Founder, Rad Group

History and Profile

The RAD Group was founded by brothers Yehuda and Zohar Zisapel in Tel Aviv, Israel. Both brothers studied electronic engineering at the Technion Israel Institute of Technology and hold MBAs from Tel Aviv University. Yehuda began his career in the 1960s working for Motorola Israel, but in 1973 decided to start his own business importing and distributing computer networking equipment. His company, Bynet, soon became Israels leading systems integrator. In 1981, his brother Zohar joined him to begin work on what was then a revolutionary idea: developing and manufacturing telecom access devices in Israel for export. They started a new company in a corner of the Bynet offices and gave it the name RAD (for Research & Development) Data Communications. RAD is now considered to be the mother of Israels hi-tech industry.

RAD soon gained notoriety for its first products, which were miniaturized modems that reduced space and electric consumption, since they were fed from the electricity in the phone line rather from an external source.

Over the past 30 years, the RAD Group has grown to include many different independent companies that develop, manufacture and market product solutions for the networking and telecommunications industry. Some have gone public on Nasdaq and some were later sold to other telecom leaders. The group typically started a new venture with a business idea from an entrepreneur or a member companys management team. Initial funding is provided by the groups founders, together with venture capital firms. Since its establishment, the group has spawned more than 185 companies, issued eight IPOs and participated in 19 mergers and acquisitions.

RAD Group is currently comprised of 10 companies, five of which are traded on Nasdaq and the remainder privately held. Member companies maintain several dozen international offices and are associated with more than 300 channel partners in 165 countries. The group has won many awards including the Business Red Herring, Internet Telephony Conference "Best in Show", Editor's Choice Awards from several industry magazines, including Network Computing. The RAD Group also sponsors RAD University and Protocols.com, leading sites for network and computer science information and reference materials.
