The Giving Tower Holiday Challenge, designed by CrowdRise, starts Nov. 24

Twenty-one recipients of the Skoll Award for Social Entrepreneurship will be participating in the Challenge and will have the opportunity to win $250,000 in prizes from the Skoll Foundation, in addition to CrowdRise prizes.

All participating Skoll Awardees are highly effective social entrepreneurs. Check out the participating Awardees and support your favorite cause!

The first bonus challenge will take place on “Giving Tuesday” (Tuesday, December 1^st). The Skoll Foundation will give a prize of $25,000 to the organization that raises the most money on that day.

The Giving Tower Holiday Challenge will end on January 7, 2016, but get in early to leverage your donation dollars for bonus prizes!
