self-improvement on social networks.

We are also proud to announce Corazón Labs was selected as a first-round grant recipient of fbFund; funded by Accel Partners and The Founders Fund.  fbFund companies are building the next-generation of applications on Facebook.

Challenge makes it simple to double-dog-dare your friends into trying something new, encourage participation  and track everyone's performance.

Maybe you’d like to challenge your friends to ‘run 3x a week’ or ‘first to a hundred pushups’ or just ‘lose that extra 10 pounds’
