The Michael J. Fox Foundation for Parkinson's Research (MJFF) it has completed and surpassed the $50 million Brin Wojcicki Challenge. Longtime foundation supporters Sergey Brin and Anne Wojcicki have matched more than $53 million in capacity-building gifts received by MJFF from January 1, 2011, to December 31, 2012.

Brin, a co-founder of Google, and Wojcicki, a co-founder of 23andMe, have been the foundation's largest donors for several years running and spearheaded the challenge to spur donors at every level to give, renew or increase giving to MJFF. Because of the enthusiasm and generosity of the foundation's community of donors, challenge-eligible giving exceeded the original goal by about $3 million, which Brin and Wojcicki have agreed to match.

"Anne and Sergey's friendship to our foundation and to Parkinson's patients worldwide is awe-inspiring," said Michael J. Fox. "As if a $50 million match weren't tremendous in its own right, they've gone above and beyond their initial commitment to match the $3 million extra ponied up by our incredible supporters. There's no doubt the challenge has made our community stronger and more vibrant in its passionate pursuit of a cure."

Over the course of two years, the challenge brought thousands of new contributors to MJFF. It also helped the foundation reactivate relationships with thousands of supporters who had given prior to 2010, and motivated over 4,000 to stretch their giving in order to double the impact of their generosity.

With the completion of the challenge, Brin’s and Wojcicki’s personal giving to MJFF totals more than $157.5 million since 2004.
