Startups are in a unique position to weave the idea of doing good into the very fabric of their culture. From the beginning days of Twitter, we aligned ourselves with giving back by associating with organizations like Charity:Water, Donors Choose, Room to Read, Product RED, Malaria No More, and others. Before we had a sales team, we had a corporate social innovation team and some of that work is brought to light at Hope 140 and Fledgling.
