Jan Koum, co-founder of WhatsApp, has given the largest single gift to an Israeli hospital, donating $200 million to Shaare Zedek Medical Center in Jerusalem through The Koum Family Foundation, the hospital says.
The hospital will be officially renamed as Koum Shaare Zedek Medical Center.
The 24-story building will encompass more than 1.5 million square feet, including new surgical and emergency care facilities.
The donation surpasses the $180 million donation made by Shmuel and Anat Harlap to Rabin Medical Center (Beilinson Hospital) in August 2025 to build the “Tower of Hope.”
“This gift reflects our confidence in a future of medical innovation and research that will benefit patients in Israel and around the world,” Koum said in a statement
Help us report truthfully on social media
As a multimedia journalist, my job is to take the quality, fact-based journalism produced by The Times of Israel newsroom and make it accessible across every platform — from Instagram posts to podcasts to short-form videos.
This is how many, especially young people, consume news these days. But misinformation is rampant on social media. Our team at ToI produces accurate, responsible short-form reporting on Israel and the Jewish world.
If you believe in the importance of factual social media journalism, please consider joining our reader support group, The Times of Israel Community. Your financial support is essential to sustain responsible multimedia reporting.
