Future Think: Agile Book Publishing Startup LeanPub

“The first copy of a Leanpub book was sold on April 21, 2010,” says Peter Armstrong, whose company Leanpub launched in 2010. “The book was Eric Ries' Startup Lessons Learned, and the price was $29.99. Not all ebooks need to cost $9.99 or less. Since then, we've paid over $700,000 in royalties to authors. Thousands of authors have signed up, and more than 100 books have earned more than $1,000 each."
