Impossible.com
Impossible is an altruism-based social network which invites people to give their services and skills away to help others. The online venture was described by Vanity Fair magazine as a "commerce-free online community". Created by Lily Cole, the site allows users to post something they would like to do or need so that others can grant their wish, creating a culture of giving. As of May 2013, Cole presented the app's beta in conjunction and with the support of Wikipedia co-founder Jimmy Wales at a special event at Cambridge University. The site has since been launched in the UK and US. It is the first Yunus social business in the UK.
