The communication of Horizon is partially inspired by some amazing thought leaders in the field of testing ideas, which we would like to reference here:

Alberto Savoia, inventor of the term "pretotyping" and author of the book "The Right It: Why So Many Ideas Fail and How to Make Sure Yours Succeed", which is a must-read for every person attempting to build a product or a company. You can buy his book here (not an affiliate link).
