Ben Rattray is the founder and Executive Chair of Change.org, the world's largest platform for social change. He started it in 2007 with a borrowed $1,000 after his brother's coming-out reframed how he thought about bystanders and responsibility. What began as a social network for activists became a petition engine that has grown to hundreds of millions of users worldwide, turning ordinary signatures into pressure on corporations and governments. Named to TIME's 100 Most Influential People and Fortune's 40 Under 40, Rattray has spent his career trying to shift the balance of power between individuals and large institutions.
