Jason Fried & David Heinemeier Hansson
37 Signals, 2010
Jason Fried and David Heinemeier Hansson founded a company named 37 Signals (nowadays called Basecamp after their flagship product). It's different from other companies. On their site is an eight bullet statement which reflects their vision. In short: it's about simplicity and clarity. Personally, I like especially #5 Customers are our investors.
Together, they wrote Rework about their ideas, their company and their vision on business. Along the book, there's a nice manifesto on ChangeThis.
