RAD Founders

In memory of our founders

Captains of industry, leaders, visionaries, mentors, philanthropists, and above all – compassionate souls. The late Zohar and Yehuda Zisapel were all that and much, much more.

Together, the Zisapel brothers founded RAD and The RAD Group in 1981, and continued on to establish many groundbreaking tech ventures in the fields of communications, biotech, AI, cyber, and more. They were also extensively involved in various public philanthropic enterprises. Their multi-faceted, larger than life personalities also extended to the arts – which they embraced wholeheartedly.

They have left a legacy that we are all immensely proud to be a part of. Their spirit will continue to guide us as we press forward in our mission, just as they would have wanted.

Yehuda and Zohar, you were beacons of wisdom with gracious hearts. You will be dearly missed.


Yehuda and Zohar Zisapel

Israel’s High-Tech Growth Engine

Research by the Tel Aviv University discovered that the RAD Group has been responsible for the creation of hundreds of Israeli startups and venture capital funds, earning Zohar and Yehuda the apt title: “The Forefathers of Israeli High Tech” and the first serial entrepreneurs of the State of Israel.
