In Memory of The Murdered

In the early morning on Saturday, October 7th, 2023, terrorist group Hamas infiltrated southern Israel and massacred innocent Israelis, from infants to seniors.

They were mercilessly killed, in unspeakable ways.

StartupHub.ai and the entire technology community pause to honor the murdered. We remember them. We honor their memory and the brightest futures they were supposed to live.

May their families and friends find solace. We grieve with you.

We pray for the release of hostages currently held in Gaza.
