Jessica Jackley co-founded Kiva and revolutionized micro-lending. Her new memoir Clay, Water, Brick tells the story of the founding of Kiva and her own personal journey from a religious family in Pittsburgh to becoming a successful social entrepreneur. This is a great conversation about personal development, entrepreneurship, starting Kiva--and then figuring out how to handle its explosive growth. 
Also: a podcast milestone! Jessica, and her husband Reza Aslan, have become the first wife and husband team to appear independently on this show. My conversation with Reza is episode 64.
