David Zapolsky said that when he became general counsel of Amazon in 2012, one of his top priorities was to build a pro bono program. It launched two years later, with a focus on using the company’s vast scale and deep legal expertise to improve access to justice for underserved people and communities in the United States and around the world.

This fall, the program reached its 10th anniversary, a milestone that led the Seattle-based company to take stock of its impact. So far, more than 2,200 legal and public policy employees have collectively volunteered more than 65,000 hours of pro bono service, an effort that has reached into 23 countries.
