About Tzedakah Multiplier

As Jews, we want to give tzedakah to support our community and the wonderful Jewish charities that help it thrive.

At the same time, we also want to have the greatest impact we can, giving to those most in need regardless of where they come from.

Tzedakah Multiplier allows us to have the best of both worlds, whilst adding more on top of our donations.

"Someone who saves a single life,
it is as if they saved the entire world."

~ Talmud
