WhatsApp founder Jan Koum is donating $200 million to Shaare Zedek Medical Center in what is being described as the largest philanthropic contribution in the history of Israel’s healthcare system, officials from the Jerusalem Hospital told JNS on Thursday.

The donation, made through the Jan Koum Family Foundation, is expected to triple the size of the Jerusalem hospital, which currently has approximately 1,000 beds. Koum, 50, who was born to a Jewish family in Ukraine and immigrated to the United States as a teenager, co-founded WhatsApp in 2009 before selling the messaging platform to Meta for approximately $19 billion in 2014.

The funds will be used to construct a new inpatient tower that will also include housing for medical staff. According to a source in Israel’s healthcare system, planning approvals for the new tower are advancing rapidly through Jerusalem’s municipal planning institutions.
